Differences between GT 10.1 Wifi and LTE [updated with benchmarks] - Galaxy Tab 10.1 General

I have both here and wanted to compile a list of differences for those who are curious. I don't have time now to take some pictures, but I'll describe the main differences I've noticed and hopefully update this over the weekend a couple of times if there is any demand.
Results unique to the Wifi version are highlighted in blue.
Results unique to the 4G/LTE version are highlighted in red.
Hardware:
Both have:
Texture and colors are identical (both are 32GB dark gray versions)
identical dimensions to the accuracy of my finger tips measuring
headphone jack slightly right of center on top bezel
data/charging connector centered on bottom bezel
3MP camera at top center of back
2MP camera slightly to the right of top center on front
microphone hole about an inch to the right of the data/charging connector
Wifi model has:
Power on left side of top bezel
Volume rocker to right of power on top bezel
speaker openings about 80% up each side bezel
two things that look like screw hole covers on each side of the data/charging slot
SVMSUNG styled logo just above center on back
CE and fine print bottom center of back
4G/LTE model has:
Power on left bezel approximately where Wifi has left speaker
Volume rocker just below power on left bezel
speaker openings about 75% as long as the Wifi model's and about 1/2 inch higher on each side bezel
micro-sim door about 1/2 inch to right of headphone jack on top bezel
(checkmark)verizon styled logo where Wifi has SVMSUNG logo
4G/LTE logo and fine print bottom center where Wifi has CE text
SVMSUNG styled logo just above 4G/LTE (aka CE fine print) area
System:
Wifi "About":
Model number: GT-P7510
Android version: 3.1
Kernel version: 2.6.36.3, [email protected] #1
Build number: HMJ37.UEKF3 P7510UEKF3
4G/LTE "About":
Model number: SCH-I905
Android version: 3.1
Kernel version: 2.6.36.3, [email protected] #1
Build number: HMJ37.EG01.SCH-I905.EG01
UI:
Wifi offers "Silent Mode, Flight Mode, and Power Off" when you long press the Power button. The 4G/LTE version offers "Silent Mode, Airplane Mode, Restart, and Power Off".
ZoinksS2k mentions: The LTE's power button is almost impossible to find by touch alone. You have to drag your finger past the speaker slot and hope you find it. It is fairly annoying.
4G/LTE web browser has a Mobile/Desktop view mode setting.
4G/LTE web browser has the Labs tab in the browser settings.
Software:
Wifi has a Samsung update procedure, 4G/LTE appears to have an Android update experience there (but I'm not sure I'd know what was stock). Both are accessed via Settings->About->System Updates.
4G/LTE version offers Automatic date/time option in System settings.
Both have the same looking Samsung camera app
4G/LTE came with Google Videos with access to Google Movie store, Wifi does not have access to the app
Wifi came with Samsung Apps store, 4G/LTE does not have it
Both were ready to download my paid apps when I went to the Market after activating them, but neither downloaded all my other apps (the Xoom I was using downloaded every app I had on my phone when I first logged in with it).
Performance:
In the parking lot outside the Verizon store I saw 23694dn/7052up/51ms ping on one try and 22027dn/8246up/49ms ping on a second try. At home I got around 12000dn/6000up/<50ms ping reliably. My home Wifi usually measures 15Mb/5Mb/18ms on both tabs for comparison, though I did get one reading of 20Mb down (on Comcast Blast! which measures 36Mbit down and around 5-6Mb up using my desktop computer).
Benchmarks (some results revised after restarting the tabs with no home-screen widgets):
Startup times (from pressing power to first graphic, first animation, lock screen):
Wifi gets (6.4s, 13.8s, 34.9s), (6.6s, 14.2s, 35.6s), 4G/LTE gets (6.1s, 16.8s, 47.3s), (~6s, 17s, 44.5s)
(Note that around the 33s mark both tabs would blip the haptic feedback sensor - the Wifi version would then show the lock screen within a second or so after that, but the 4G/LTE version would take another 10 seconds or so with the animation being slightly slower and a bit laggy before it would get to the lock screen - this could be the time when it is registering on the 4G network even though it happened whether wifi or mobile data was on or not, but Airplane mode did cut off about 3s from the total time to the lock screen.)
Nenamark1: Wifi gets 31.3fps consistently, 4G/LTE gets ~42fps
Nenamark2: Wifi gets 19.1fps consistently, 4G/LTE gets 19.3fps consistently
Linpack Single Threaded: Wifi gets ~31, 4G/LTE gets ~30
Linpack Multi-threaded: Wifi gets ~30~57, 4G/LTE gets ~56
Vellamo: Wifi gets 952, 967, 4G/LTE gets 957, 955

Thanks for assembling this, you covered everything very well.
I own both flavors. The LTE's power button is almost impossible to find by touch alone. You have to drag your finger past the speaker slot and hope you find it. It is fairly annoying.
Good news is that LTE is the real deal. I saw 17mbit down at my office.
As for battery life, the LTE version had 50% charge out of the box and it ran down to 25% over 2 hours with heavy data access (speedtest.net, automatic app installs from the Market, Exchange email, etc.). If this holds true with normal usage, we are looking at about 5 hours of total life, give or take.

Would either of you guys mind getting some info from either Android System info OR shell cmds?
Android System Info (or whatever you prefer)
----------------------------
System Tab -> CPU Expanded and copy the info listed
Shell cmds

cat /proc/cpuinfo
cat /proc/meminfo
Thanks if you can, no big if you cant...

Any info on rooting the LTE version?

I just added some benchmark data showing some interesting results...
30% gain in 3D performance in 4G/LTE version
Much faster I/O score in Quadrant Advanced - could this be simply due to aging on the memory cells on my older Wifi version?
Linpack did not achieve any higher results on my Wifi version with multi-threading, but the 4G/LTE nearly doubles its score...

This is the only thing holding me back from getting one at this point. Is anyone brave enough to try yet?

Could you run a Vellamo benchmark please? https://market.android.com/details?id=com.quicinc.vellamo&feature=search_result
There is something with the wifi 3.1 update that does not get along with Quadrant, and the scores aren't particularly useful when comparing across roms.
Also the linpack multi-thread test should be in the 60's at least, not 30's...

Just difference in the software.... The wifi tab just came out in June. Compare with a rom or once we get the touchwize update.

Vellamo got a 958 on the Verizon version I have at work (on the mobile radio, not wifi) which looks about the same score as the sample galaxy tab 10.1 in the results table at the end. I'll wait until I get home and can run the app back to back on both tabs to record the scores in the original post.

Just to be clear, I will only be doing testing and noting differences on the stock ROMs for each device.

The only way to be completely fair would be to fully erase all information from both and make sure that the same exact programs are running on each. I am highly skeptical in the 3D and I/O speeds. Doesn't make sense as the graphical and processor components are identical.

The I/O speeds make sense if they changed the file system used or symlinked it. Though I don't know what filesystem either one uses so I guess we'll need to find out.
Updated drivers could explain the difference in the 3D scores.
I played with the Verizon version and it seemed faster than the Wifi one I played with a while back.

Just as a reminder to everyone, Samsung has indeed done this "type" of thing before on their tablets. Take a look at the 3G Galaxy Tab 7 " and the Wifi Only Galaxy Tab 7". Especially pay very close attention to the Imagination Tech PowerVR chip used in both.
I am unware of any major different variations of Tegra2 chips besides memory speeds so I dont know what it could be. It would help to have more detailed output from cpuinfo and meminfo....hint hint hint...

Well I returned my wifi today to be able to get the LTE. I was glad to see the movie rentals (like on the A500), but upset that the netflix apk that works on the wifi does not work on the LTE. It acts just like the Acer, you can browse but you get a video com error. A change to the lib file perhaps....

i have experienced the speed difference (UI) when i was in verizon store while playing with 4g lte tab. Tonight i have flashed the TW Rom by Calkulin and now my wifi tab is faster than before but still not like 4g LTE tab. Excellent comparison by flarbear.

Love to see a rom dump of this new tab

Honestly, I don't think believe they could be any different. Just wait tell we get the updated American version of touchwize.

You're rooted and probably running a different ROM. These tests are done with stock ROMs.

As someone pointed out, you are running a different ROM and I am running stock so it could be apples and oranges.
However, having said that, today my 4G tab is only getting a consistent 38 on the multi-threaded Linpack so it would appear that this may be due to some setup I've done (app running in the background, etc.) that is preventing my CPU from devoting both processors to the benchmark. I'll play around and see if I can get one or both of them to recover (though I'm not willing to do factory resets and go through the extensive setup processes for sake of this experiment - I'll just annotate or remove the figures if I can't figure out what might be causing the problem).

My State of the Evo address

For starters i love this phones hardware. Almost all of the hardware specs of this phone are excellent. The 1ghz CPU by qualcom is a very good choice, but not quite a bleeding edge chip. Having a dedicated gpu would have been a better choice for the resolution and processing requirements of the other parts of the phone (gpu's can accelerate alot more than games).
512MB ram is a good choice and certainly enough for most needs. However ram is super duper cheap these days and i'd much rather have 1gb of good system ram than 1gb of extra storage space(which is what the evo gives us). the 4.3 inch screen is certainly sufficient, and in this space i dont think there really are much better panels resolution and aperture wise available.
I have certainly enjoyed playing with the 8MP camera in video and snapshot mode, but it also has its flaws. Being very sensitive to light the framerate (in video mode) can go from whats looks like(because i have no way of actually checking) lower 20's to less than 10 frames per second. Also while the 8MP sensor allows for nifty resolution it does not make for the cleanest image(in both video and snapshot mode). Due to lower quality optics being used and very little logic. I've found that flash also seems not to fire in correct sync with the (non mechanical IE FAKE)shutter of the camera sensor. Causing blurred images even with the flash on, I even attempted to circumvent this problem by manually setting the iso mode in the camera options to no avail. Also i really love the back facing camera and i would love it if i could actually use it for something.
I dont like fring its ugly and buggy, i dont like QIK. I dont know what it is, i just know i wont like it(J/K). It honestly never even occured to me that skype was not available for android yet (dont even mention that verizon peice of garbage). And it looks like we get it either until the end of the year. If even then (for video). I have had some opportunity to try out video on evo. And while some videos look good they are often not the right ratio and leave the screen largely empty. Some videos had obvious framerate & sound sync issues. Even on youtube. Let me go ahead and say i have not even played with HDMI, fm radio, or bluetooth. None of these do i really use, However i do like lots of extras and you cant go wrong with any of those. I tried only a few games out primarily raging thunder 2. I was not impressed by this games performance in the slightest. I would expect a 1ghz phone to be able to outperform atleast a Nintendo DS. I believe this part calls for a facepalm. I believe im supposed to thank HTC and their infinite wisdom for the 30FPS cap on the phone.
As for the 4G. I live in north dallas inbetween several major urban area in small residential housing area. Before signing up for my evo one quick trip to the sprint website and a little bit of address information would have me believe that im lit up like a christmas tree for miles all directions with 4G connectivity. Only after purchasing and bringing the phone home to realize i have no 4g connectivity at all do i back to the sprint website and go back to my coverage map. Yup see there i am all green, oh wait what is that? when i zoom in all the sudden the maps starts looking like swiss cheese. As i zoom all the way down my exact house do i see im not covered at all. Upon further testing i found that many areas that say they have 4G do not infact have 4G at all. After finding a 4G tower less than a mile away from my home. I drive to the tower to test my phones capability. Speedtest avarage download being 4300kbps or 430Kilobytes per second or about 4mbps. And upload averaging almost exactly 1000kbps or 100 Kilobytes per second or 1mbps. Well bellow the stated peak limit of 10mbps for downloads, and 1.8mbps peak of uploads. Mind you im sitting right beside this tower. I get much further from my home wifi. As i start driving, toward my house. I lose coverage in less than half a mile. Upon further consideration of this 4G technology i dont think its ever gonna work(right). I cant imagine them putting up enough towers to blanket a city yet alone suburbs or rural. There just is'nt enough real estate. I want to love this device, however this phone needs alot of love, and up against the onslaught on new phones just over the horizon, it needs it quick. Otherwise this could easily end up a dead end long before it ever reachs maturity. I have only owned my phone for 10 days. I will return it(if major upgrades dont happen soon) and go back to a peice of crap metroPCS phone for another six months while i wait for either this phone to get its act together or jump on one of the new LTE phones from the competition. Also i'd like to ask, what would you guys prefer a new single network connection combining all voice and data functions like the new LTE network verizon/metropcs is designing with possibly less bandwidth or a multiple network IE seperate voice and data connections with possibly more bandiwidth. Please consider all the known implications before replying. Lets keep this critiquing unbiased as possible please. If theres anything major please feel free to let me know.
And all i wanted was video conferencing.

I drove around till i got 4g signal Then meandered my way around following signal strength til i could see it. Never got full bars for 4g until i had line of sight. It was a big tower too. Still only covered about 1/2 to 3/4 of a mile.

It's been mentioned by Sprint, Most Blog Sites, and Many other People. It has been shown on upload tests through SpeedTest, DSLReports, etc that its capped at 1MB or very close to it.
Please provide a screen shot of 1.7Mb/s upload as I have not seen that either and I have fast 4G where I live.
Here is from the developers site about cap.

Next time I am on Michigan & Randolph, I will run a test. I dont have it in my current log as I blanked my phone last week for whitslack rom.

Atrix Data Speed Vs iPhone 4 / LG Vortex

I know all Atrix users are having problems with slower data connections than using, say the iPhone 4. So I went ahead and did a quick video of, iPhone 4 and Verizon LG Vortex to show the speed difference. Clearly you can see that the Atrix is very slow in uploading, but overall was pretty close in download speeds with the iPhone 4. I have been averaging around 2.2 Mps down and .31 upload. Overall when using the Atrix phone to look up anything in the Market place or web browsing, and or using a app that requires data, it feels much faster overall. Could be that the Dual-Core is helping in this. My next video will be, comparing on the phone browsing and using data apps to compare.
Here is the link to the video: http://www.youtube.com/watch?v=yA72kfo856w

If you are interested in testing the device's ultimate speed, you shouldn't be running the test at the same time right next to each other period. That causes channel interference (if on same carrier) which degrades performance, not to mention you are cutting available air interface resources in half in on the same channel/sector. That is not going to tell you jack **** about how the device performs (as far as above average potential) in comparison to another device on the same network...it only really shows how each device handles data in a crappy signal situation....interestingly ATT was better than VZW.
It has been demonstrated that the Atrix lacks HSUPA and will generally not perform as well as iPhone4 (or other HSUPA enabled device) until this problem is resolved.

I think you misunderstood what he's saying. In the real world, you could be standing next to someone else using an AT&T phone, so that interference isn't unexpected. How the device handles that kind of interference is absolutely relevant information.

In the real world, he probably isn't running a speedtest right when you are.
It's still pointless as if you are trying to compare device speeds on the network, you need to give them ideal conditions....otherwise you aren't comparing the devices really. This is obvious because it isn't showing the Atrix's crippled network interface.

I'm not even sure I understand what you're arguing. Someone next to you is not using a data connection if they're not running a speedtest? Because that's what it sounds like you're saying. The speed of the phone next to you is irrelevant. A phone pulling down 1000Mbps as opposed to 100Mbps won't magically decrease the surrounding signal. In modern devices, channel interference like that isn't really a problem anyway.

Based on that statement, it looks like you really don't understand how WCDMA (or CDMA based) networks work. Channel noise, noise floor, neighboring interference etc. plays a huge part in network performance. So yes, even though signal receive strength may be very good, performance can suffer from channel noise...and I see it all the time in cell overlap areas (I live in one even).
And when you have two devices like that operating right next to each other using the same ARFCN, especially if one is in the upload portion of the test, it's going to create additional noise that the other device is going to have to fight through....then throw on top that both devices are fighting for whatever is left of free resources on the site..which is basically cutting whatever is left in half....if they are on the same sector/channel.

I understand the theory, I've just never seen it affect a device in practice to any noticeable degree. I might get 3.15 down with no other devices nearby, and 3.14 down with several others running at once (GSM and CDMA devices).
Living in an area with several carriers fighting for the airways can impact performance, but again, I've never seen a big enough difference to care. Maybe you've just been in areas with outdated hardware or poor filtering. This is all from personal experience, however, and I live in Chicagoland where there is no shortage of service from any carrier.
I know some have said that having all 3 devices and running the test can affect the performances when running data. I was hoping to try to run a test that could show what would happen if you were out and happen to be close to other smartphones that might be accessing data.
I will post another video showing how the data performance is, by running the speed test one at a time. I did try that today, and I can say that whether I had all three running at the same time or run speed test one at a time, the speeds didn't not change much; maybe only .04 difference. So having all three running the speed test would only affect around .04 to .06 difference in download speed.
I will also do a test to compare the speed to open browser and going to websites.
Also when I was doing the speed test today with my Atrix, I was using it as a mobile hot spot to provide internet to my Samsung Galaxy Tab, and the download speeds on the Atrix was very good. I got around 3.0 Mbps down and .29 Mbps upload; which is very slow compared to my iPhone 4. Hopefully soon this will be fixed.
So in real world situations if others around me are using their phones/data I shouldn't judge how my phone performs based on that? Individual testing is fantastic, but I'm rarely the only person in the room with an AT&T smartphone so it's not practical. Everyday use throughout the day (speedtest app or not) is the only real way to judge data performance in my book.
Besides, the speedtest app can go from 1.2 to 3.4 to .08mbps in 3 consecutive tests. It's all over the place.
For browsing the Atrix should open pages quicker because the processor will help out along with the network speeds.

Big wifi limitation on sg ii !

Hi there
I found a BIG limitation in the SG II Wifi.
The problem is that: the Wifi class on the SG II is N but each time you try to put it online, getting a signal from your router, your MAX wifi speed connection will be ALWAYS at 65mb/s
(off course my router support WiFi N and i perform a check also on other routers from friends of mine having, finally, the same result)
Now i'm running the custom rom from LitePro (K8 kernel based) and this problem still there.
I presume it is only a software limitation and not an hardware limitation.
Can someone find a solution? Is it maybe necessary to modify the apks that make the Wifi work like we did with the camera sound?

Interesting. How are you calculating the connection speed?
@wifi-settings, click on the connected network and the shown mbit's will never be over 65... And in the app: overlook fing (nice network tool) will say the same.
Why would you need 600 Mbps on a mobile phone?
I have an dual N band router too but seriously on my phone I don't see the point of more them 20 mbps...

Why not?
If i pay a phone 600 euros and who made it tell me that the Wifi is N so i WANT a WiFi N because my money are real money, not charms
I a lot more concerned with battery life and wifi range on my G2 then how fast it goes
I noticed when I use G instead of N the range seems be increase.

Unfortunatly i think that the battery problem is a tecnology problem: you have what you can have from this kind of tecnology, we can just make it a bit better but to have a reasonable time of charge we need a new kind of battery tecnology, compared to what the actual phone SLCD and Amoled screens ask to work .
Make sure you are on a channel without other APs.
To the OP, find an Android mobile phone that connects at a higher data speed than 65-72 Mbps and then come back with another dramatic thread.
Can you guys please do some research before making these dramatic threads?
Have u guys seen any difference in real life use ?
Forget about the numbers .
I always do video chats and works great.

This is the expected speed of 802.11n on a small device.
QAM-64 modulation delivers at most 65-72Mbit/s on devices without MIMO. A cell phone will not have MIMO capability for cost and size reasons (requires several antennas).
No vendor provides MIMO wifi chips for cell-phone usage, so even if you tried you would get rotten battery life and a huge cell phone as the MIMO chipsets are designed for having mains power or laptop batteries, and the antennas need physical separation.
This assumes 20 MHz channel. 11n does allow for a 40MHz channel, but you will never get this in practice on the 2.4GHz band as the standard requires devices to look for interferers in the band and back off to 20MHz channel for a long time if they see any. Given how crowded the 2.4GHz band is you will always see interferers hence you will always be forced to use 20MHz channels.
Search for 802.11n-2009 on wikipedia. (I'd post the link but the forum will not allow it)
Nevermind wifi speed. I used to get good signal sat in bed with my sgs 1. With this one I get 1 bar or no connection at all. Sometimes if i turn the phone I get enough for it to resume a download.
Fair enough 1 bar gives suffient speed but it drops completely
I've tried playing with channels, changing n/g to just g etc but the signal is just weak. Nothing changed with my router, my old phone got 2/3 bar signal, my wife's HTC desire gets 2. The laptop full bars.
I'm hoping this will be fixed in a firmware update some time.
Shame cus otherwise I love this phone. (Although bit miffed with Yamaha instead of wolfsen sound, hope they release version with wolfsen. Or sgs3 )

Well in theory you should get better range with n chipset (though some are reporting the opposite!)
So you pay more money to get N and with it better range and slightly better throughput than G ?

Same with me. Witn iPhone 4 I had 2 bars and good connection, with SGS2 I am forced to switch off wifi and using 3G instead, because no more than one bar of signal and I can't open any web page. I just ordered Netgear WN3000 repeater and I hope it will help me to increase the signal, but I will have more antennas in my bedroom to frying my small brain

Very mediocre WiFi Performance?

Hey everyone,
I currently have a Note 4 and an iPhone 6 and I use a Netgear Nighthawk AC1900 router at home for WiFi.
When in my room, my Note 4 only reaches the speeds shown in the attached picture while my iPhone reaches the maximum speed possible on my connection, which is 90.
They are both on a 5Ghz network. The exact same of course. How can it be there is such a dramatic difference? I'm really thinking of returning it if there isn't a solution. I really love this phone though so I hope it won't be necessary.
EDIT: I'm reviving my own thread, since I found out something important. After restarting my Note, the speed test easily reaches the same maximum as my iPhone 6. After a while however, it drops back to 30-ish or lower.
It can't possibly be that this is a good thing, right?
do you connect your device at the same time ?
I don't know if it's still the problem with todays device, but my past experience (like 1 or 2 years ago), apple device (ipad and macbook in my friends and my experience) use wifi in some way so other device have worse wifi speed
But that just our experience in my college wifi network.
Yes they were both connected at the same time. Disconnecting my iPhone and MacBook didn't help either unfortunately.

Apple iPhone 6 comes with single band wireless AC adapter with duel-channel bonding 2Tx.
Galaxy Note 4 comes with dual band wireless AC adapter with tri-channel bonding 2Tx.
-->Single band wireless adapters have better peak performance because they are only connected to one antenna and all routers prioritize single PHY channel first. On the other hand, dual band wireless adapters have better consistent performance with higher max speeds because they are connected to two PHY channels, but have to sort out the distortions coming from two antennas. Some distortions can cancel out the signal that the device actually receives.
its the speedtest app which is messed up. i have a 25mbps connection and the desktop correctly shows 25mbps but the app shows 36mbps. try putting a 1 gigabyte file on an internal server and copy it to the iphone and note with dukto. you should get 144mbps or whatever your wifi speed is. 1 gigabyte at 144mbps should be around 1 minute to transfer.

So if I understand correctly, what you're saying is that in the long run, let's say when streaming or playing an online game, the Note 4 can more easily maintain a stable and fast connection, even though speedtest shows a fairly mediocre result due to it being like a 10 ten second test?

Yes that is absolutely correct! Single band adapters are made for peak performances and dual band adapters are for long-term consistency.

That sounds like a good thing. However if the speed is severely fluctuating every speedtest, I will contact Samsung Software Engineers to look into the issue.

I have just contacted Samsung Netherlands and the guy I had on the phone insisted at first that it was my internet provider and the modem. After I told him I used a high-end router, not the WIFI modem my ISP provides, he kept on saying it was the router. Even after I thoroughly explained that all other devices worked fine in the same room, he kept on saying it was the router. All-in-all, completely useless, I would say. Are there any other things you can think off? Or any other XDA members to help out please!?
Try with 2.4 GHz.
5 GHz WiFi is extremely poor when travelling through walls.
Note 4 has a very small and insignificant antenna thus speeds drop tremendously when there's a wall in between WiFi router and phone.
I believe iPhone uses the whole metal strips on top and bottom as antenna
I have an Asus AC66U. On my Note 4, when connected with 5 GHz, and I am in line of sight with the router, I am able to receive a good speed ~ 200 Mbps. When in my own room, there's a wall, I can only get 12 mbps to 30 mbps.
However, my desktop uses an Asus PCE-AC66 wifi card. I am able to achieve max speeds of ~200 Mbps with speedtest. (It has 3 huge antennas).
Edit: My Desktop is in the same room where I fail to get any good 5 GHz speed on Note 4.
In the end, I just use 2.4 GHz...

Great, thanks. Can't wait to hear what they have to say.
until you do an actual test (i.e. transfer a file across from the network and time it) youre not going to get any useful responses.
like i said - the speedtest app is not useful as a test. its buggy and broken. its not your router. its the app youre using.

WiFi slow performance, is this fixable ??

Hi Xda,
Got this new ASUS Zenfone 3 Zoom ZE553KL phone and wondering if I am able to change the wifi driver or system configuration because its locked down to only 802.11g often my phone gets only 54mpbs !! While my other phone 150mbps on my 2.4g router. Also the phone does not support 5ghz or dual band so it only can go up to 72mbps in the best case which it is not even capable of 5 out of the 10 times I use it.
This really sucks because I see a notable connectivity slow down compared to my older phones !! When downloading or watching a YouTube video.. Ridiculous that Asus did cut corners on the wifi connectivity back to a standard that was introduced between 2003 and 2009 !!!
The Snapdragon specifications website shows it should support 802.11ac 5g.
In my old Lenovo phone sits the same SoC, and it does have proper wifi connectivity.
Did ASUS cheat, is it really a snapdragon or a Mediatek processor? Mac address vendor of the wifi hardware shows Asus rebranding.
Can I even root this puppy?
Snapdragon specs say:
Wi-Fi Standards: 802.11ac Wave 2, 802.11a/b/g, 802.11n
Wi-Fi Spectral Bands: 2.4 GHz, 5 GHz
Peak speed: 433 Mbps
Channel Utilization: 20/40/80 MHz
MIMO Configuration: 1x1 (1-stream)
Peak QAM: 256 QAM
Wi-Fi Features: MU-MIMO, Integrated baseband
Even my 90 euro budget phone from back in 2014 went to up 150mbps..
I also have a bad feeling that there are a lot of cut corners on the wifi hotspot as well that I will have to use weekly for work.
If there's no proper way of fixing this. No more Asus phones for me. I already have a bad feeling that I need to VOID my warranty for it to be able to change anything like usually..
Other issues about the phone:
Bottom screen has two light halo effects in the screen (QC error !!!!)
And like always some problems (bugs) and removed features (latest firmware as of today)
1(bug). Set screen brightness to low, open camera app, close camera app, now the screen brightness will not always go completely down to what it was..
2. Show navigation bar feature missing. Change volume sound cannot be disabled.. Volume increasement half the steps of my Lenovo and previous phones. Blue screeen filter can't be modified, the default setting is useless because you can hardly see the difference.
Pros:
Regular software updates
Good camera
Amoled screen (but if you are unlucky you get a screen with halo in the bottom)
5000mah battery !
Other than that it seems to be a good phone for this amount of money.
You seems to be very confused. I've absolutely no problems with the wifi. It easily reaches 8-9MB/s on my 2.4GHz network and since I don't really care for the inferior 5GHz one that I do have but never use due to much weaker signal.
It's not the best phone in the world, but for the 140 bucks I paid for it, certainly it's a nice one.
I think you've set your expectations too high really.I see you've got a P2, I've had it for a while too and to be honest The Z3Z is better in so many ways, especially Camera, Speaker, Build, Price etc.
I'm afraid that you'll have to deal with the slow speed on wi-fi. I have a 100 mbps connection at home, and all phones i've tested get 95-105 speeds on speed tests, but the Zoom S is stuck at 54mbps. Unless you're willing to develop for this phone and see if there's something barring it from going faster software-wise, it is what it is.

You're right. It indeed is a good phone and the camera is better(speaker wise, I would prefer the Lenovo P2 but that's a personal opinion I guess), but I was disappointed about the WiFi, but yeah I'll just live with it. Seems they just didn't care about 5g for some reason. In my region 5G works a lot better then 2.4 even on longer range because of a lot of interference on the 2.4 spectrum. But yeah whatever, it works. The speed is indeed not terrible. Have done some more testing also with a WiFi hotspot I made and used in the hotel last time (worked flawlessly). I was in Germany and had a solid 4G connection, I guess the testing was in some way affected because of a poor cell reception or something (testing was done at home), or the DSL line at home had a slowdown at that time also not uncommon to happen..

I just deal with it, it is no big deal. Have been using the phone now for quite some time and it is fine. The only thing that sucks is that often in places where I go 2.4g spectrum is filled up with bull**** and it slows down or loses connection strength, this is why I would prefer 5g also, but alright. It is not going to happen..
Hey, I also had problems with slow WiFi. Almost to the unusable levels.
I've found out that switching Bluetooth OFF. Fixes the problem. Internet works back at full speed provided by ISP, and WiFi at routers' max.
I'm not sure if it's another firmware bug, or issue with MiBand/Bluetooth speakers.
I hope this trick will work for you
