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

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.

Does anyone know what is the maximum HSDPA speed on th TyTN? 1.5 or 7.2 mbits?
Thanks
1.5mb. That is the max speed for the chip in the tytn.
I thought the protocol of first generation was 1.8Mbps.
Second gen. is 3.6Mbit/s
HSDPA - theoretical vs actual
Yes, the theoretical speeds are 1.8 Mbps, 3.6 Mbps, 7.2 Mbps, 14.4 Mbps download speed for HSDPA. Of course the emphasis here is on "theoretical" assuming ideal environment, no other users, sufficient backhaul capacity, proximity to base station etc. The next generation, HSUPA will support faster upload speeds as well, also in multiples of 1.8 Mbps.
The Hermes supports, again theoretically, 1.8 Mbps download speed based on HSDPA. HTC Kaiser is expected to support HSUPA as well, but not sure at what bandwidth.
Practical speeds I've seen on my Dopod 838 Pro range from 650 - 850 kbps most of the times, with very rare peaks of 1.1 Mbps max. Plentiful in any case ...
Some interesting bits on HSxPA market adoption and trends here http://www.gsacom.com/.
Indeed it comes down to theory. However the point of the question was how fast the Tytn can be.
The point is that is not the chip that dictates the speed but the protocol that "chip" is usibg. You know just to continue the whole chip metaphor.
I myself have never reached anything over 500kbps... ever. But remember that no one is ever going to hit 1.8mbps due to packets and the way info is transferred through the architecture.
Wikipedia has some interesting breakdown of all the technologies.
I've seen 1.2mbps on my laptop through HSDPA here in Brum (whilst using the phone as a wireless modem) - once you let the device settle down, leave it in one place, it gets pretty decent speeds. It's VERY picky about where I have it in my room though, because the house kills all the 3G signal. In town, it's fine, but the handset's CPU just slows everything down anyway.
Most I've ever seen is a peak of 1.28Mbps, I've seen regular near-500kbps upload speeds though! Which is very nice. @ agovinoveritas - sounds like you're not HSDPA-enabled, you're just surfing at regular 3G speeds (576kbps, iirc?)... You tried ringing up your network operator and blagging HSDPA off them?
^^^^^^ Here in Canada, they have only "soft" released it. Basically what that means is that since most people here are not very tech savvy, the providers announces HSDPA to be available but they are still testing it. Just to show you how cheesy that is, they have not even released any HSDPA enabled devices yet. Just a Sierra Aircard, and since the amount of people out of the general population who would use just a Sierra aircard is minuscule you can see where they are going with this....
They get PR points for releasing the technology first even though they do not give anyone any phones to go along with it. For those of use WHO HAVE hsdpa devices, if we call, the CSRs either do not know what the hell they are talking about or they will use the "we do not support your handset" cheat out.
I've peaked just above 800kbit on the Hermes so far. Same as what I get with my Treo 750v + HSDPA hack.
On my Cingular 8525 the fastest I've got is about 800kbps.
1.2mbps here. Thing is my device doesnt show its connected to HSDPA?!?
Both the icon and fieldtest_157 dont show that im connected!? (this is during a download)

In Australia on Telstra you get about 1.2 Mbps - 1.4 Mbps.
Hmm well considering you are paying through the nose for data if you are wish Telstra than I'd say a "lowly" 800kbit is better than 1.4mbit.
$79.95 for 1GB? No thank you. I'm happy with 1GB data + unlimited email + other stuff for $30

It's pointless to fine-grain compare bandwidth test results of an internet connection with a shared interface (in this case the 2G/3G air interface) since the amount of load on the interface is changing constantly. At best you could use your speed test to get in the ballpark (i.e. to confirm you are really on HSDPA) but to say 'my radio dropped my download speed from 800Kb/s to 600Kb/s' is probably erroneous because a difference of 200Kb/s is definitely well within the variation of an air interface. Unless of course you conduct a controlled experiment with both radios with many data points and you can actually draw a distinct correlation.
Edit: By the way a somewhat more accurate bandwidth test is here:
http://i.dslr.net/tinyspeedtest.html
Atleast most of you have the 3g network. Here in my area of CT we only have the Edge network. I wonder what's taking tmobile so long to make it available in my area.
I generally get 400-600kbps on good 3G signal.
You're being measured by kiloBITs per second, not kiloBYTEs

Speed test is wrong
the way the cellular internet works: all data in all networks are sent in packets of information. if you run a longer test then you will get a more accurate reading. mine said 572kb/s

Not wrong, but not accurate.
There is no accurate way of testing, as there is no constant speed.
Somedays you might get a really high measure on speed test, while you might get a low speed that is unheard of on other days.
So I mostly agree with you xDDD

b=bit B=byte, just so you know.
One should also keep in mind that bandwidth tests usually only test the speed of a single connection. As anyone who has used a multi-part download manager knows, you can usually get a higher overall throughput with multiple connections going. This seems especially the case with UMTS networks, where carriers probably throttle down individual connections to try ensuring that each user gets a fair slice of the pie.
I notice that I get the fastest speeds on my 3G when I am downloading usenet files (10 concurrent connections, each connection only downloading a few hundred kb at a time). While I might max my single connection download speed at 400 Kb/sec (50KByte/sec), I can usually get about 1.5MBit/sec when running multiple connections to a fast server. It's not the 3.6MBit/sec advertised, but not bad either.

I don't know if this has anything to do with it but I have mine set for GSM atuo prl
Slightly faster data speeds and I run them all........the.............freaking.............time.
Not a world of difference from the N1 and it may only be a placebo effect but I'll put it this way: You certainly won't lose speed when you upgrade to this phone. First speed test went north of 3Mbps and that area consistently got me 2.4-2.6Mbps with the N1.
First time I ran speedtest app I got 565kbps down and 1258kbps up...looked reversed to me.
Ran it again just now and got 979 down 582 up.
It's seems to be pretty random on the test, but real-usage on the browser is fast enough to have me very satisfied.

Hmm.. I am getting anywhere from 2 to 2.4 Mb/s Down and 1.7 Mb/s Up (Raleigh/Cary NC).
The Vibrant doesnt support HSPA+ so the max you could get is 7.2mbps. Not sure if the N1 is HSPA+ compatible though.

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.

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.
Like an increasing number of others I've 'cut the cord' and only use my mobile for internet access. I use USB tethering to share the data with my other devices through a router. I've done a few benchmarks to determine the USB tethering bandwidth and latency between my recently bought Oneplus 8 and it's tethered device. For testing purposes I connected it directly to my laptop and booted into Windows and Ubuntu. A few issues cropped up that I thought worth highlighting to determine what the underlying causes are, to see if there's anything that can be done to resolve them and to get results from others from there devices. Relatively high latencies were observed as were connectivity issues during high bandwidth throughput. Results as below
Latency (average of 100 pings, other devices added for comparison)

The latency results shows that
The Oneplus 8 has around 3-5 times higher latency than the older and significantly lower specced Samsung XCover3 and Moto G6 Play.
The windows latency timings are around twice that of the Unbuntu timings for the Oneplus, the OS type had a minimal effect on the XCover 3 and no influence on the G6
USB3 adds another 0.5ms to the round trip times in both directions over USB2 for windows but has no influence when used under Ubuntu
The response times from the mobile devices are generally slower than the response times from the laptop
Given the push for 5G for higher bandwidth and lower latencies (when SA 5G NR is implemented at least) it's a step backward to have increased latency times on the user equipment. This will add to the overall latency. I'm interested in seeing what latency times other people are getting over USB tethering not just for the Oneplus 8 but for other makes and models too.
Bandwidth (measured using iperf3 server on the laptop and client on the Oneplus via USB3 average of 10 seconds)

The iperf tests caused stability issues on the Oneplus 8 whilst using USB3. The USB interface would often crash and reset (confirmed via crash log in logcat). No stability issues were identified using USB2 or WiFi. USB2 bandwidth was maxed out so figures not included in the results. Max Wifi speeds were around 550Mbit/s using 5Ghz WiFi 5. I don't have another Wifi 6 device to test with.
The bandwidth results shows that
There's stability issues using USB3 when pushing bandwidth to the limit
Both download and uploads were faster in Ubuntu
Windows needed two parallel streams to attain top speed whereas in Ubuntu one was sufficient
In usage terms max download speeds (from the Oneplus to the laptop) averaged at 652Mbit/s and and upload speed max averaged out at 947Mbit/s. I don't know if this is a hardware or driver/software limit.
With 5G already hitting over 1Gbit/s the tethering bandwidth over USB3 is now the limiting factor. There's plenty of bandwidth available on the underlying USB3 protocol so its up to manufacturers to push the envelope. It's worth mentioning that Oneplus are still one of only a small selection of manufacturers that have implemented USB3 so this is worth commending. Most are still releasing phones restricted to USB2 speeds. I don't have another mobile with USB3 to test with for comparison. As with the latency findings I'm interested in seeing what results others are getting for USB3 tethering for both the Oneplus 8 and other devices.
App used for testing on the mobiles was Hurricane Electrics 'he.net Network Tools'
Well I jus got my OnePlus 8 thru Vzw 2days ago an must say deff impressed with speeds. Only walked out my front door an on ookla & Xfinity tests clocked over 100mb d.l. & round 8-10upload on only 4g.. I'd upload screen's but can't rem how too. Can't wait to see OnePlus 8 Vzw on 5g
