WiFi speeds

Is it just me or are WiFi speeds on these tablets very slow? If anyone know Of a fix it would be appreciated.

I've seen other posts where people have found a small gap in the shell resulting in poor contact inside for the wifi leads. Some were able to squeeze the shell tighter to help and some opened the back and tried to carefully adjust the pins to make better contact. At least one person broke a contact pin, so be careful if you try that. My wi-fi connection and speeds are very good.

I can download a 100 Mb file in less than a minute, and web pages take less that 3 second to load.
Though, I have a 30 Mb/s connection from Charter that I can constantly get up to 45 for some reason.

Last night I transferred GBytes of data via ADB (i did a full tablet wipe and a bunch of restores) and couldn't help but notice that sustained data transfer via (wired) ADB is only about 1.4 Mbytes/sec. Sort of pathetic waiting around for a half-hour to transfer a 2.5 GB file.
Anyway, not to jack the OP (which is about WiFi), but I wanted to try and figure out what my best options are for high-speed backup (I have a 32 GB N7!) - including WiFi as an option.
Ran a couple of file transfer trials this morning using a ROM file that was 150,137,068 bytes.
Results first, more detail on each setup follows. (The results are compared in terms of data payload per second; in the cases where protocol overhead is high, the wire-speeds would be higher than calculated)
[1] SMB/CIFS write via WiFi : 518sec => 2.32 Mbits/sec. UGH (best of three trials)
[2] FTP put via WiFi : 109sec => 11.06 Mbits/sec
[3] FTP get via WiFi : 121sec => 9.9 Mbits/sec
[4] adb pull via USB : 78sec => 15.4 Mbits/sec
[5] adb push via USB : 117sec => 10.3 Mbits/sec
[6]* OTG VFAT write via USB: 33sec => 36.4 Mbits/sec
[7]* MTP copy via USB 13sec => 92.4 Mbits/sec
In the WiFi cases:
- Linksys WRT54G (802.11g) router circa 2006 [ 802.11g theoretical bw 54 Mbps ] 6' away -35 dBm signal
- SMB/CIFS "server" Windows Xp SP3 laptop on 100 Mbps Ethernet segment attached to router
- N7 SMB client app ES File Manager
- FTP Server app (Andreas Liebig) on N7
- FTP client app Windows Xp default ftp app for both push and pull
- Windows box on Ethernet, N7 only on WiFi.
In the OTG case:
- 8 GB Sandisk Class 2 microSD card on a card reader attached to OTG cable; single partition, empty card, VFAT formatting.
In the ADB case:
- adb v 1.0.31, Win 7 Pro x64, Quad-Core i5, USB 2.0
Observing the WinXp task manager performance tab during CIFS or FTP transfers, the wired (Ethernet) link would show a high degree of variability, oscillating between 5 Mbps to 15 Mbps instantaneous rates. Hard to say whether this is a router performance issue or something else (11 Mbits/sec approaches 1000 pkts/sec at a MTU of 1500 bytes).
* The numbers for the OTG and MTP transfer tests are possibly questionable as the role of file caching is unknown - the times given here are only the times that the file transfer dialog(s) remain on-screen. (The writes could be completing in the background out of cache with nothing showing on the screen) In particular, note that the OTG copy involved a "Class 2" microSD card - and yet the write speed seemed closer to 4.5 Mbytes/sec, rather than 2 Mbytes/sec
The SMB/CIFS transfer times are quite pathetic; but as with all performance measurements, any participant in the test could be the long pole in the tent. For instance, the issue might be the ES File Manager app. I did not test with a N7 CIFS-capable kernel.
Also, it would also appear that performance of ADB for file transfers are quite poor - well, in comparison to MTP anyway. Too bad MTP doesn't preserve file timestamps (as well as all sorts of other oddities).
Apologies in advance for using file transfer as a network benchmarking method - my connection to the outside world (DSL) peaks at only 3.8 Mbits/second, so I would need to set up some kind of LAN server to benchmark network performance in absence of flash-memory or hard-drive writes.
Anybody have any performance numbers to share for:
- OTG mounts of hard drives or SSD devices with NTFS or ext4 file systems
- CIFS/SMB network mounts with CIFS-capable kernels
- WiFi speed tests when remote server is via FiOS or U-Verse fiber connection?
========================================================================
[Edit] -- Added some network-only test results.
FWIW, I ran a couple of tests using the "netcat" tool to evaluate the same setup without writing files to mass storage devices. It turned out that a terminal emulator app that I have has a busybox with netcat built in, so I booted the WinXp laptop into a Ubuntu Live CD (10.04LTS), and ran netcat TCP write tests in both directions. I also used "iptraf" to look at peak bit rates.
Result? Peak observed speeds were about 16.6 Mbits/second, and sustained-average results were in the 11-12 Mbit/second range. From that I conclude that that the FTP transfer tests were probably network-limited, as testing involving file writes were really no slower than this. Whether that means the "N7 is WiFi limited" or something else is not deducible from the data I collected. In this case, it takes three to tango (N7 - router - laptop).
I do note however that blahman179 said above "100 MB in less than a minute" - 100 MB in 60 seconds is about 14 Mbits/second. Only a little faster than what I observed - right in the same neighborhood.
Note that I had my WiFi router set to G-only. I suppose that the basic bit rate with huge signals in the -30 dBm range means that the radios are indeed transferring packets at a 54 Mbit/sec bit rate - but with a duty factor of less than 30%.

@OP:
fwiw, I did a little searching. Some XDA N7 users with high speed ISP connections report peak download rates of 20-30 Mbps when connected to networks that can do much better than this using PCs.
That "speedtest.net" app reports peak values recorded over short intervals - I suppose that sustained (average) transfer rates are somewhat worse than this.

Also Comcast and probably others boost your speed for the first part of your download making burst speeds optimistic.

I have 60 megabit, ive not sat and worked it out, but I often get speeds of 5500kb/s on torrents over wifi. Maybe not making use of all my bandwidth, but the downloads come in quick enough for me.

Having trouble with all wifi connections on my nexus 7... When i am on my home wifi I get 5mbps where all other g connected devices pull 25mbps. That's not so much of a problem. When I am tethered to my cellphone via wifi I get 600kbps with the nexus 7, but my cellphone tethered via wifi to my pc is 4mbps. I'm concluding something is wrong with the link speed on my nexus 7 but don't know what to do about it. Any help would be appreciated cause I really need more then 600kbps when not at home, especially when my phone regularly pulls 10mbps in my area.

I agree with the WiFi connection being slow with the n7.IMho I've seen better download speeds with my galaxy tab 2. I've also noticed with certain kernels the WiFi is faster.stock to me is the best and now I'm running the faux kernel and it ain't too bad.

I just tried the speedtest.net app and averaged about 9.4Mbs down and .68 up. Stock rom, rooted JB.

Game streaming is useless over wifi

Lots of stuttering, input lag and low bandwidth warnings using 5GHz band with router only four meters away.
Thought this would be a good way to game on my TV instead of a monitor but it seems to be useless unless you content them using an Ethernet cable.
Would be nice if they highlighted this in more reviews, it seemed to work fairly well with the shield tablet but it's worse on shield tv.

Even over wifi the streaming stutters, I'm regretting buying this.
Apparently a ping of 4 isn't high enough for smooth gaming.

Hello!
I bought some TP-Link AV1200's and it's working nicely over these. I must add I'm living in a newly built house so the cabling will be up to par. Also my PC is on a different loop to my Shield but the throughput is still excellent.

Depends on your router actually. Have you tried connecting to the closer band? instead of 5. Also check your settings because routers now and days saves devices addresses which can slow down the process or you could configure your settings to your shields IP and give that top priority.

Are both the shield and pc on the same wireless network? I think it's worth it to run an Ethernet to the shield (or the computer) so you're not making the router/access point congested. A high quality wireless device with mimo capabilities might perform ok.
My setup has shield connected by Ethernet and my laptop on wifi, no issues here even using 1080p and high settings

I've tried with an Ethernet cable, sometimes it's very smooth but lags randomly which ruins the experience.
The software isn't up-to the job.

I can't even got it play nicely over Ethernet, testing over wifi further is a waste of time at this point.

So it looks that the problem is the router or internet connection. And not the shield. It's just a guess.
Can you test streams with a Laptop or PC via Wlan and Lan? Then you can find out

Thats strange I have had no issue with this good to know through.

Game streaming requires a 30 - 50 Mbps consistent connection (I believe). When it comes to wireless networking there are a lot of factors that affect your max. speed (connectivity protocol - a/b/g/n/ac ?, distance from router or access point, # of connected devices, interference, etc..,) ...
Actual wireless speeds vary significantly from the above theoretical maximum speeds due to:
distance - distance from the access point, as well as any physical obstructions, such as walls, signal-blocking or reflecting materials affect signal propagation and reduce speed
interference - other wireless networks and devices in the same frequency in the same area affect performance
shared bandwidth - available bandwidth is shared between all users on the same wireless network
Below is a breakdown of actual real-life average speeds you can expect from wireless routers within a reasonable distance, with low interference and small number of simultaneous clients:
802.11b - 2-3 Mbps downstream, up to 5-6 Mbps with some vendor-specific extensions.
802.11g - ~20 Mbps downstream
802.11n - 40-50 Mbps typical, varying greatly depending on configuration, whether it is mixed or N-only network, the number of bonded channels, etc. Specifying a channel, and using 40MHz channels can help achieve 70-80Mbps with some newer routers. Up to 100 Mbps achievable with more expensive commercial equipment with 8x8 arrays, gigabit ports, etc.
802.11ac - 70-100+ Mbps typical, higher speeds possible over short distances without many obstacles, with newer generation 802.11ac routers, and client adapters capable of multiple streams.

Works perfect fot me with asus router downstairs

I've been gaming loads through GeForce NOW, it's connected via ethernet through a pair of cheap homeplugs to the router.
Our ADSL is awful too, only 4Mbps asynchronous (500KB/s download bandwidth, about 50KB/s upload bandwidth).
I'm actually amazed it works so well - the video stream itself occasionally has artefacts or gets a bit pixelated, but it never stutters and never has any lag responding to gamepad inputs.
We're used to occasionally pixelated video when our ADSL fluctuates while watching youtube videos etc. anyway so this isn't a big deal.
It takes a bit of getting used to when gaming, but the overall experience is still fun and I accept that the video quality will get better when we move to a home with fibre.
Does anyone know how GeForce NOW actually manages to achieve such a native response time to gamepad inputs?
I find it truly remarkable that I can press a button on the gamepad and not notice any latency with the reaction on screen.
Surely any action must be sending packets over our crappy ADSL to NVIDIA's servers, routing them to the game's virtual machine, causing an effect in game, then streaming the video back over our crappy ADSL to be rendered on the TV.
I'd expect 100-200 milliseconds of latency at either side of that transaction (even over UDP), which I'd expect to ruin the gaming experience of real time games such as FPS / racing games.

Another thing to note, WiFi is a half-duplex CSMA/CA connection. It can either send or receive at one time, not both, like Ethernet. Collision Sense will "listen" to see if anyone is broadcasting. Collision Avoidance will set a random timeframe, when transmission will retry. While this is happening extremely fast, there's a chance to lag there. If you must use WiFi instead of ethernet, try to dedicate a separate SSID for streaming, and make sure that nobody else connecting to that particular one. Try to set it to uncongested channel as well.

Unless you have one of the newer routers mu-mimo and other new software helps keep wifi onpar with ethernet

Works fine here. Asus Router is several rooms over and using a USB wifi stick in PC.
So its probably something other than the shield.

Didn't realize that. Will look it up.

I can't get this to stream from my laptop. It says that i need a GTX 600 series or better but my laptop has a GTX 770M.

WiFi Speed Dependent on CHarging Status

I have discovered that my US996 Unlocked and rooted device has typical down/up speeds of 90d/55u when the phone is not being charged. When the phone is connected to a charger the typical speeds are 400d/270u. This is very repeatable. The phone is 3 feet from the router. am using speed.net and the ping is 4 to 5 ms for both configurations. If I start the test with no charger and plug the charger in during the test the speed increases dramatically to the higher values. The verizon.net speed test for the router on my gigabit plan was fairly consistent at 948d and 931u. Is there a way to get the higher WiFi throughput while not connected to a charger?

Which router are you using btw ?
90 Mbs down seems like single stream N, on 2.4Ghz
400 Mbs down is single stream AC at 5Ghz
Can you check what your link speed says in the wifi props on the phone
the single sim V20 is dual stream so you'd expect a doubling of that speed, should be able to do 800Mbs on AC and 180 Mbs on N at 2.4ghz with a dual stream router which most are these days.
The dual sim V20 is unfortunately single stream so my max speeds are 90 & 400Mbs instead of being twice as much
I don't understand why you get a difference in speed in the first place. Should not matter plugged or not

I'm using the Vz provided G1100 gateway router. Link speed on the phone says 866 Mbps. I'm at a loss too - probably a phone hardware problem. BTW, I'm still on US99610d deodexed ROM with Xposed and other mods that I wouldn't THINK would cause the problem, but....

Bolded bit implies your connection is good. Dual AC which i was expecting.
It's possible LG ramp down speeds to conserve battery. Not an issue with general use only with downloading

Bolded bit? Sorry, but I don't know what bit you are talking about. I remember seeing nothing bolded in anything wifi (settings). My router lists my V20 connection as "802.11ac" and I see nothing indicating any problem. But the phone still has the problem. I'm wondering if there could be an antenna problem and the charger conection acts as an extra antenna? Obviously l'm groping in the dark now.

Speed up phone's WiFi? Speedtest shows slower than actual internet speed

Is the phone's MODEM speed limited to about 50mb/s?
My internet speed is 70mb/s as measured on my computer WiFi connected to my router. The max speed the phone is showing is 48-49mb/s while sitting right next to the computer.
Is there a (build.prop) mod that can speed up the phone's WiFi speed? The phone is rooted.

Your computer could be using a different wifi band than your phone. Computer's speed often differ from the phone. Also both the devices have different types of antenna and operating power levels. I don't think messing with the build.prop would do much.

Let me ask the question differently. Is anyone getting faster than 50mbps on this phone? I am not.
The phone is rooted running 2/1/19 update OEM ROM Potter. Router b/g/n broadcasting at 2.4gHz only. Internet download speed is 90-100mbps on the computer. Phone and computer speeds measured 2 feet away from the router using the same Comcast speedtest app..

Question Nothing phone 1 wifi issue and power saving mode ON by default.

Hi, i have the phone 1 when ever I use a wifi 4 router internet internet speed is significantly low like 800 kbps to 2 Mbps on a 100 MBPS internet.
When I checked with router it says wifi power saving mode is on by phone.
Anyone know how to access engineering mode?
Can i disable wifi power saving some how?

Even I am facing the same issue. my one plus shows 65 to 85 Mbps but nothing phone shows less than 1 Mbps

Changed wifi to 802.11 n mode only and using 40 MHz band right now speed improved to 25-30 Mbps but never found a solution to this my OnePlus 7 next to me constantly hit 85-90 mpbs from same place and connected to same WiFi.
And i don't know what is causing this issue yet.
I seen only with wifi 5 GHz the phone wifi is working fine but if you connect to 2.4ghz speed is very bad.

Same it work for 1 to 2 times in speedtest results shows high speeds but drops to 1-3mbps instantly.
Currently I'm getting 30 Mbps by following above method can you try once and see if 802.11 n only not working try 802.11 G + N it is also working fine for me.

Yeah i am using 2.4(B+G+N) one tweak i did now is set channel width to 20MHz or 40MHz instead of 20/40 and now back to 70 to 90 Mbps now its not dropping ensured by disconnecting also restarting device

I am facing the similar issue.how did u solve ur problem?

I use a wifi6 router so my phone has almost 700 MBps download in same room with the router and between walls I have almost 600 MBps . ISP provider is set on 1GB . Those results are by default settings on my phone .
There is under developper options one particular setting about internet connection reffering to " limit network bandwith download " which is applied to all networks that phone is connecting to . There are some limits like = No limits , 128 kbps , 256 kbps , 1Mbps , 5 MBps and 15 MBps . Choose NO Limits .
Mine No limits is by default .
It is known that bandwith on 2,4 GB band is much lower than 5GB . Also router must know and deal with MiMo wich Nothing Phone is capable . Even more there are plenty of WiFi analyzer apks that help you to choose the best channels and/or band on both 2,4 GB and 5 GB band of router . I must say between 3 new phones I use now , Nothing Phone has the best modem radio chip .
I guess you all faced to some router problems . Phone is fine , except that limit set under developper settings which like I said is set to NO Limits but check it out
