What all speed are you guys connected at? Apparently it's supposed to be a Wireless-N capable chip in the TF, correct?
I am only achieving a link speed of 72Mbps. But it feels much much slower when transferring large files... or, is it my imagination?
It only has 2.4 ghz N not 5 ghz N. 5 ghz N goes up to 300 mbps, 2.4 tops out at 130 mbps.
Sent from my Transformer TF101 using XDA Premium App
Thanks. Then I am still not achieving that speed (130mbps). I'm only getting 72. Wonder what is up with that.
same here @72. i check to make sure i my router set only to N (i understand having it set to G/N will cause the speed to get capped even lower, but nope, it's pure n)
I don't need a signature.
someone correct me if im wrong, but my understanding is that all devices in your network need to be "N" capable in order to achieve close to maximum speeds. If you have a laptop running on g' then by default your network run on g speeds.
Not sure if this might be the case here
I know my Linksys can transmit two different wireless signals. One signal is on "B/G" mode and the other signal is on pure "N" mode. Still it only connects at 72MBPS
The transformer and Android devices in general seem to be a bit slow in transferring large files. It might be do to smaller packet sized, inefficiencies in the Wifi stack, filesystem, or other factors. I think any reasonable rate of Wifi link speed is going to suffice. I do not detect much of a difference in actually throughput as I move through the house and the Link speed changes.
Yup. 72Mbps here too on a Linksys e2000 running dd-wrt. Same on my HTC Desire.

You'd need to sue an entire industry or two for every tech product ever produced.
I was wandering the same thing...no -n connection...but my laptop connects fine
I think you should get started on looking at lawyers. We will be right behind you.

Interesting that others are getting 72Mbps. I can't get more than 65Mbps, regardless of whether my network is configured for BGN or N only. That's with the tablet as close as two feet from the router, and no other networks visible (low density residential area, so likely not too much interference). Tried standard (20Mhz) and wide (40Mhz) channels, as well. Signal strength shows as excellent, but nothing gets me above 65Mbps.
That said, speed seems fine to me. Range could be better, my laptop will happily pick up wifi for almost double the distance of my Transformer, but inside the house it works pretty reasonably anywhere on either floor.
How is it false advertising? They said Wireless N, it supports wireless N. They never said it supports wireless N @ 300mbps .
EDIT: And before anyone tries to argue, no, Wireless N connection classification just says up to 300mbps supported, not that it has to be 300mbps, it's a frequency not a speed classification.
Max speed is 65 . 6 FEET away from my dlink dir 655
Just having a bit of fun..... breathe... breathe...

Sadley yes, the transformer is only able to achieve 72Mbps wireless N speeds
In a previous thread i started (Here: http://forum.xda-developers.com/showthread.php?t=1068468)
In short Wireless N gets its major speed increase from using multiple channels (MIMO) and the increase in bandwidth between channels 20 Mhz or 40 Mhz
There is no difference in speeds between 2.4Ghz and 5Ghz, 5Ghz is ideal due to the least amount of interference in that RF spectrum but the downside is that 5Ghz does not go as far as 2.4Ghz
Anyways
Here is a chart for reference

Wireless N Link speeds are usually organized by the MCS Index number in FCC documents, and in the FCC documents for the Transformer it maxed at MCS7 index which is 72.2 Mbps (20mhz channel width, 1 MIMO stream)
MCS Index Chart
http://en.wikipedia.org/wiki/Wireless_N#Data_rates
FCC Reports: See SAR Report 1 of 4
https://apps.fcc.gov/oetcf/eas/repo...ame=N&application_id=434077&fcc_id='MSQTF101'
We wont know for sure what a firmware update might fix, which i doubt that is a solution for it anyway, i think its a hardware limitation, but just need to confirm the WLAN chip on the transformer
The FCC documents state its a Murata LBEH19UQJC, but in the various files in the transformer it has clues to suspect its a Broadcom chip, we need a full teardown!!
Overall, the transformer could have seen higher speeds if
A: It allowed a 40 Mhz Channel instead of 20 Mhz
B: It included a 2nd antenna
For some routers like my dlink dir-655 you need to configure to wpa2 and aes and auto channel to get 300mb/s connections.
Sitting within a few feet of my router (Linksys E2000, 802.11n), I am geting 9000 Kbps down and 2000 Kbps up. We're on Comcast Blast!(16000/2000).
Speed means battery drain, so most mobile devices support 802.11n and doing a big step forward in speed,but the standard it self allows 600 MBits in 2.4 GHz and 5 GHz. Most mobile devices suppport only low MCS rates that max out in 72.2 MBits. Did you see an 600 MBit capable AP /router lately?
It is great to have 11n but even the ipad supports only one stream and 72 MBit. Even Cisco delivers in their enterprise gear only 300 MBits not 450 like some others. So be happy with the speed it got, i am sure that the CPU would not be able to handle more than that.
GS5 performs really well on Google Gigabit Fiber and Sprint tri-band. I'm getting up to 180Mbps on Google Fiber and around 40Mbps LTE indoors at home, though I'm just a few blocks from a cellsite. The first 3 results are on Google Gigabit Fiber in KC, the second three are Sprint Spark.
BTW, more on Google Fiber here...

I don't understand, isn't google fiber just using your wifi? Do other phones have trouble downloading through your wifi or is the S5 performing differently?

Just showing the max the WiFi on this phone can do. In comparison, a Nexus 7 (2013) can do about 100Mbps, the N7 (2012) and Galaxy S3 and can do about 25-40. I suspect most SnapDragon 801 devices would be over 150Mbps as well, not sure.

Interesting - I've never paid attention to Wifi performance and was not aware performance varied greatly between devices. Thanks for sharing.
Good to know the wifi speeds are that high. This is my fastest speed on band 41 so far
Yeah. I'd crap my pants if I had Google Fiber... Wow.
I wish my phone would actually use band 41. Ive seen Spark speeds a whopping once. The rest of the time I see my awesome 3-4mb down.
Josh dew on youtube got his S5 to mid 800s download speeds using Google fiber.

Which must be BS because WiFi won't do that fast lol.
These phones MAX at 866Mbps IF you have a AC router and happen to be close enough.
That said, WiFi has roughly 40% overhead so the best you could even imagine to ever see on this phone would be around the 500Mbps mark.
FWIW the speedtest app isn't dead accurate in itself.
It often times shows my speed faster vs. what I know my speed can do because I know exactly what my speed wall is and the upload on the phone generally overshoots it lol.
I'd be hard pressed to see you get gig through dual AC 1300Mbps routers even due to overhead.
They would be close but wired still wins.
I think for the OP the first thing would be what kind of router do you have, what band are you connected on and what was the link rate at time of test?
I bet the phone can do more but your wireless is the limit.

Please continue in the thread for dedicated Spark thread http://forum.xda-developers.com/showthread.php?t=2720215
So I ordered 2 Z5's from Amazon (2 different sellers); one green and one white to see which color I'd prefer. Now that I have both, quality is equal (and great!) and I like both colors, so decided to dig deeper.
There are some differences in the 2 devices. They are clearly built for different regions as the white one came in a Spectre 007 package and uses the LTE symbol for LTE and the green one came in a standard Sony package, included a QCH10 charger and shows 4G for LTE speeds. (For reference I know that 4G = LTE). The white one is Rev1 and the green is Rev4.
Here is interesting part. I've setup and configured both phones to be completely identical from brightness to apps to theme, etc. When I run a speed test using the exact same SIM card, I get way different numbers.
Running 2 consecutive tests in each on T-Mobile band 4 with the phone on my desk in the exact same position, the white one (Rev1) gives me 82.38 Down/4.71 Up and 47.55 Down/3.52 Up. The green one (Rev4) gives me 94.83 Down/8.56 Up and 97.10 Down/4.81 Up.
On WiFi, they are consistent.
Running both Antutu and Quadrant on both devices is also interesting. Antutu scores virtually the same on each; the white (Rev1) at 56k and the green (Rev4) at 55k. However, on Quadrant, the white (Rev1) is 29k and the green (Rev4) is 22k.
So what I'm looking for are comments/thoughts from some of you senior folks on the differences to help me decide on which device to keep.
Thanks!!
Since you have gone through all the trouble to set both if them up, I would run a bigger sample size of speed tests, say at least 10. I think you would see things average out and be fairly equal. Only thing is, not sure how your data plan is configured. Running network speed test in bunches chews data.
You actually ordered unboxed and used 2 different devices just because you couldn't pick which color you like before sending back the one you don't want?
I know that you 'can' but...
Sent from my E6653
This post made me rerun Antutu 64-bit today on my black E6653 Rev3 where I got 55,092 only last night, same as OP.
Well, the latest result is 62,511
So, any of you guys notice the phone is faster during the day than at night?
Screenshots of Antutu results, phone uptime is 72 hours so no reboots between runs.

Might depend on signal from carrier and how stable it is. Many apps and system modules launch during different conditions taking a toll on battery and perfomance for a moment. For example changing connectivity from 3G/4G to WiFi will launch several apps that will then be closed down as RAM is needed for other apps that you have launched (these apps might be in standby but do some work from time to time or just when initially launched). This due to them being set by respective app to start when connectivity changes happen. So bench them in airplane mode and with wifi off. Restart before benching.
Mine shows to be slower than the z4 lol
@EQ2000
We all know benches can vary from run to run. My point about 55K vs 62.5K on my Z5 is that OP shouldn't be using benchmark results to choose between two "identical" phones.

Agreed unless this indicates one phone is throttling due to inadequate application of thermal paste and/or contact between SoC and heatsink.
OP (me) isn't using benchmarks to decide. My questions (and title) were around speed variations between the 2 devices and the benchmarks were just a secondary observation.
I was just curious if it could be possible that Rev1 and Rev4 have different radios.
My apologies if the benchmarks became the root of this discussion.
One more observation today. The green Rev4 has a VoLTE button in the Quick Access drop down and the white Rev1 does not.
Screencap from router shows how slow on my AC network at 5G compared to my other phone (Moto X Pure Edition):
(yes, it's weird that MXPE is labeled 'Lenovo' and actual Lenovo G5+ isn't, but I also confirmed by MAC addresses)

I'd appreciate hearing from any others having a similar issue. But also if you're not and are getting comparable speeds to your other wifi devices. That way I'll know whether to return for a hopefully normal replacement, or if it's more widespread maybe just return and forget it. Thanks.
Edit 1 - phone is still totally stock, btw, XT1687 60GB/4GB RAM no-ads $299 version from Amazon.
Edit 2 - According to specs on Motorola's site it only does 802.11 N and not AC, so 150 Mbps may be all it'll do. The Pure got close to 300 full speed on my previous N network though. I do like everything else about the G5 Plus so far, just expected even mid-range phones would handle AC + dual band by now.
I think moto g5 only support 2.4 Ghz (5 Ghz is optional in 802.11n specs) so theoretical 150 Mbps is max. In reality the moto g5 will probably never break 100 Mbps...

According to GSMArena both G5 and G5 Plus support dual band N, and also Motorola's US site for G5 Plus (G5 not is US).
On 5 GHz mine is getting 150 Mbps tops, and 72 on 2.4 GHz. My Moto XPE got 300/144 as tops on my former N router, so I wonder if others are maybe getting that on their G5 Plus on different equipment, or if 150 is the absolute best it can do. On my AC router the MXPE gets 866 Mbps (I think that's tops) but my Acer laptop only gets 433 (still a great speed), so go figure.
You are right it does support dual channel. So maybe 40 MHz channel bonding isn't enabled by default? This would explain why you speed is half of the mxpe
Same problem here on my Indian variant of G5 plus (4+32GB). Haven't done anything with it yet, completely stock. The first two days were good, could touch 22 mbps (yeah, that's quite a big deal in India ) but now it only goes upto 5 mbps whereas other devices show 22 mbps now also. Help would be appreciated.

Same, I have 3x3 5ghz and 2.4ghz on my router and my speeds almost mirror your's..150 on A and 78 on 2.4ghz N. My Galaxy S5 connects at 866 on the same network.
My home internet is 200 Mbit and I can only get about 98 on the Moto G5+, it's a disappointment but I like the phone otherwise enough to look over it...but it's almost enough to spend that $35 restock fee Best Buy charges.
My S5 seems snappier at doing Internet related activities due to it being capable of pulling down the full 200Mbit. The battery life of the G5+ is insanely good likely in part due to this.
I just picked up a Samsung Tab A and noticed it only gets ~200 - 250 Mbps down when the rest of my devices are getting my advertised speed of 400 Mbps. They all have the same wifi standards so I'm not sure why I'm not getting my full bandwidth on this tablet. All the tests were done on the 5Ghz SSID and right next to the router.
Devices I've tested on:
Desktop 1 (Hardwired and wireless)
Desktop 2 (Wireless)
MacBook Pro 2017
iPhone X
iPad 2
Testing sites:
speedtest.net
fast.com
They're all showing 400+ Mbps except the tablet.

Is this a defective tablet or normal? I'm not particularly complaining about the speeds I'm getting now but I just want to make sure that this isn't a defect.
I saw another user complaint about it to.
He had speed problems with 5Ghz and with 2.4Ghz it was better
~200 - 250 Mbps is a good value, my T510 gets only ~150 Mbps download and (which is interesting) ~280 Mbps upload - tested with speedtest.net app on 5Ghz WiFi. On 2,4Ghz WiFi is the situation a bit worse ~50/50Mbps only. And my wired internet speed is 500/500 Mbps.

I'm not particularly complaining about the speed I'm getting but more curious if this was something wrong with the tablet. All the devices including the Tab A are 802.11 n which should mean they are capable of 600 Mbps on 5 Ghz band. All the other devices did it without issue yet the Tab A wasn't able to.
I picked up a replacement TaB A and it gets the same speeds. I uploaded a video of it as well.
It seems like you all are discussing the wi-fi performance without listing one important spec, how many transmit or receive streams does the Tab A (2019) support? Samsung doesn't list anywhere in its literature how many wi-fi steams it supports, but given it's a low-end device, I am willing to bet something that it only has 1x1 steam. The iPhone X comes with 2x2 steams and the MacBook Pro comes with the unprecedented 3x3. The rest of performance equation depends on how well the internal antennas are designed and other factors. And we all know, after the Tab S5e Wifi problems, that even Samsung can't sometimes design antenna for proper operation (the Huawei Mediapad M5 also had wifi problems because of using the same antenna for wifi and BT).
A 1x1 802.11ac device can link up with the router up to 400Mbps, but in real life this number is MUCH lower even when in the same room with the router (you can check this number in the wifi settings by tapping the SSID). And then, a whole lot of that bandwidth lost because wi-fi wastes a lot of it on its own transmission record-keeping. As a result, it's entirely fine to see 150Mbps in a bandwidth test even though you're linked to a router at say 250Mbps.

The Tab A (2019), and others listed above should have 802.11ac, not n. 600Mbps was a theoretical peak for 802.11n with a 40Mhz channel width ONLY with a 4 streams, and such devices never materialized. A typical 802.11n device had one stream, or two, so the cap was at 150 or 300 respectively. The cap for link speed of 802.11ac devices with two streams is 800ish.

I actually had no idea about the number of antennas. Everything I've read and what you've said have pointed to the Tab A having a 1x1 stream and I can live with that. Just had my head scratching for few days.
Thank you it's much appreciated.
Hi All, I have the same problem with t510. Thank all for the infos and clearing this topic.
Sadly my wifi speed is around 66 mbps and and I getting half of that on my tablet is plain s*it. Just tried nvidia now on my tablet and that was when I realised this problem. Got 540p with like 10fps.. Shame on samsung to go so cheap on the wifi chip.. :\
My Samsung Galaxy Tab A 10.1 (2019) SM-T510 simply refused to work properly on 5Ghz wifi, no matter what I did.
My solution was to go into my router device's admin page, and create two seperately named network SSIDs for the different frequencies:
- My 2.4Ghz Wifi network
- My 5Ghz Wifi network
I set the tablet to only use "My 2.4Ghz Wifi network", and no issues since.
