Hello,
Does anyone know the theoretical WiFi speed of the SM-T700 in 2.5G and 5G band? Or can someone share his?
Using OOKLA Speedtast, I'm having approx 8-10Mbps under 5Ghz band with mine (similar perf w/ file transfer from a computer on local computer) but I get 40-50Mbps with other connected devices (eg S7E).
I'm not sure if this is due to device capability or ROM issue, so I'd like to know what is to be expected first.
Thanks for your input.
The 802.11AC, which works in the 5GHz bands, gives roughly 100Mbps per stream for a 20MHz wide channel. The Tab S supports two steams and up to 80MHz wide channels, so in theory with the right access point setup, you have theoretical speed of 800-900Mbps. However, in real life wi-fi wastes at least half of its bandwidth on it's own protocols house keeping. So the Tab S should be able to have 200-400Mbps ish link to the router under the optimal conditions. However, the 5GHz band slows down tremendously with the distance or behind the walls. If you're not getting 50Mbps in the speed test, then you're probably far away from the wireless access point, or there is some kind of interference going on. The 2.4GHz band is slower and usually more congested, but it reaches greater distances.
Thanks for the details @Akopps.
From what I observed, the max download speed on my Tab S is averaging 7MBps whereas using my laptop I get at least 20MBps. Same distance from router, located <4m and 2.5m up without obstructions.
So its seems I'm way below theoretical capable speeds but unsure why.

I've been doing a lot of speed tests the last few days and I can't seem to download anything faster than 1mbit/sec.
I realize that would be normal for 3g but the thing is I am not getting more than 1mbit with wifi also.
I've tested my 3g connection with both ip dashboard and gprs monitor and get equal results. IP dashboard seems to be the only decent program for checking my wifi speeds and it reports between 1 and 1.2 mbit/sec.
I know the max hsdpa speed is 1.8mbit and given overhead that translates to about 1.3-1.5 in a perfect environment.
Does this cap also affect the wifi max speeds? I would think wifi would still be 11mbit and 54mbit as the respective b and g standards specify.
Kinda sucks if regardless of wifi or wan the speeds can't top 1-1.2mbit.
I believe it is right. I never had much luck downloading faster in wifi either. Maybe try different ROMS and see if they are any faster...
:bump:
Need more answers.

Strange, but my friend has 50Mbit broadband. I did a Speedtest.net on his computer and got 35Mbps as a result. I did the same speedtest on my phone via wifi and it couldn't get past 10mbps (1MB/s) Which is strange as Wireless G is 54MBps, and there were no other devices connected Wirelessly.
Speedtest does not measure speed of your wifi LAN. 54Mbps is max wifi local speed, not the speed at which internet data is actually transferred. So speedtest.net must not show 54Mbps.

Phones are slower than computers while processing the received internet data. That would have caused it to show less speed. IMO 10Mbps is still pretty good for a mobile device with network of 802.11g class.

Phone's are not slower at processing the data from the internet, that's just stupid. It's a simple measurement of speed. And I wasn't measuring the LAN speed, I wanted to measure the speed the phone got via Wi-Fi when connected to a 50Mbit source. The speed hits a virtual roof at 1MB/s and backs off. As in the speed leaps from 0kbs to 800kbs in seconds and works up to 1024kbs the drops back to around 800kbs and slowly works back to 1000kbs but the test ends before this happens and the speed is registered as around 8Mbit.
Even when uploading using Wi-Fi File Explorer the max rate attainable is 10Mbit (1MB/s) even if the network is Wireless G (54Mbps) or Wireless N (150Mbps). Now this is a running a Sensation ROM (RCMix S v2.0) which has updated the Wi-Fi to Wireless N.
Now, my point is, 10Mbps is a good speed, you're not wrong, but why place a Wireless G card into the phone if it will only ever see Wireless B speeds? It wastes radio frequency by being on the 2.4 GHz range when it won't fully utilise all of that. Just seems daft to me. I'm sure a tablet connected to a 50Mbit source would receive closer than my Desire.
I have some CCNA certifications under my belt, so I'm adept at networking, I just thought either my phone was a problem or it was a design. Like you say, 10Mbit isn't to be sniffed at.
Flashed CM11 last nite and so far it exceeds my expectations except for wifi speeds. I have an ac router and my network speeds are 150mbps down. But on this phone my speed on 2.4ghz tops of at 41mbps (not terrible, a little faster than my old phone) but 5ghz its really struggling. I just tested it at 14 mbps. That's after switching channels on my router before that it came in between 32 and 36. I was expecting it to break 100mbps since my other ac devices consistently clock in at 150 to 165mbps.
Before I start poking around my router settings...anyone else experiencing slower speeds? I didn't try the speed tests on stock fire os so not sure if this issue is restricted to CM or fire phone or if its my network settings. Just looking for others' experiences.
Hello,
I have just switched fiber provider at my place (FTTH) and I am now getting a whopping 1000 Mbps on my connection via gigabit ethernet.
My ISPs internet "box" luckily comes with 4 gigabit ports but only 2.4 Ghz WiFi (...). Which means that what actually reaches my portable devices is somewhere between 20 to 70 mbps, depending on my location in the house.
So, I ordered a Netgear R6220 to connect to my ISPs box, whose WiFi I will disable, hoping to get the most out of my fiber connection.
I see that this router supports simultenous Dual Band (300 + 867) which should exceed my ISPs downstream bitrate. But I wonder whether the 835 on my P2XL will be able to benefit from the simultaneous Dual Band transmission.
According to the specs it should (https://www.qualcomm.com/products/snapdragon-835-mobile-platform):
Wi-Fi
Wi-Fi Standards: 802.11ad, 802.11ac Wave 2, 802.11a/b/g, 802.11n
Wi-Fi Spectral Bands: 2.4 GHz, 5 GHz, 60 GHz
Peak speed: 867 Mbps
Channel Utilization: 20/40/80 MHz
MIMO Configuration: 2x2 (2-stream)
Peak QAM: 256 QAM
Wi-Fi Features: MU-MIMO, Multi-gigabit Wi-Fi, Dual-band simultaneous (DBS), Integrated baseband

But since the Peak speed is listed as 867 mbps, I'm not sure...
Anyone was ever able to max out the P2XLs WiFi speed?
Thanks!
This is mine today, I have seen higher from my wifi but this is right now.
This is the best speed i got using the 2XL
1Gbit line using a Asus RT-AX88U router.

Wow, this is impressive! I didn't think our Pixels could reach that level of performance!
I guess that the bottleneck for me will still be on the router, then, since I'm not getting anything quite like yours (smaller budget).
I'm getting from Amazon an R6220 and a couple of Tp Links (archer c7 - 1750 and archer c1200), the best one gets to stay! ?
You should be able to reach decent speeds with any of those routers the only reason I bought this one is so i don't need to buy another rooter any time soon.

There you can find fast access point for low price with high quality, I use only these
Is this max network speed for a70?
This is screenshoot form wifi settings.
On other phones i get 130mbps.
mine says 65. Ultra slow downloads. Heard some people talkin about using the 5 Ghz band of certain equipped routers or n band. It is just so slow downloading from my wlan I figured it must have something greater wrong with it. Like hackers again...who knows.
This is what mine says
On mine is 72mbps network speed and cant get over 49mbps download speeed on speedtest.net
433Mpbs on 802.11AC for me
I get a picture 130 mbps on my oreo device but both pie devices say 65 mBps.
My 1000/100/10 switch connects ethernet to various devices which easily shuttle the expected 80-130 actual MB/s around of large filetypes.
I don't have any sort of 5 Ghz router just the crappy device that the company sent out. And on that the MAC filter keeps getting disabled which increases my paranoia. Till 2 weeks ago I used the same crappy standard gateway/router for 6 years and frankly it was equal or better experience. At least that one started up reasonably fast. And its MAC filter was always on. But that could just indicate that the neighborhood brats had an easy backdoor to that one and didn't have to brute force off the MAC filter.
In my opinion the MAC filter getting disabled (now a few different times it has happened) indicatives a much much larger problem
I have been intending to get my own personal router for a while but there are too many options so I haven't had the scope to choose one yet.
Other phone in network displays 117mbps and is a Pie.
On same network 2.4ghz on s8,s7 i get 130mbps and on a70 72mbps max.
Just tried 5ghz on same network and got 150mbps it is a little faster.
But on 2.4ghz 72mbps is max.
hi guys
i have also same problem . cannot connect more than 72mbps , with 5ghz 150mbps max . something wrong but i could not find what is the problem .
you guys found any solution ?
mine has 72mb on 2.4 and 433mb on 5g...

i think all a70 phones are like that
I just tested and got 158Mbs with a 5Ghz wifi connection, although only around 60Mps on 2.4Ghz.

I'll check mine later and see if I can figure out what's happening
Right next to the router I can see 96mbps in 2.4Ghz
Must be something wrong. I got 433mbps.
Nothing is wrong.
The Snapdragon 675 supports 2x2 chains on WiFi, but the A70 only has a 1x1 antenna so it connects at half the speed.
Link speeds on the A70 are as follows:
2.4 GHz = 72 Mbps
2.4 GHz (with 256 QAM) = 96 Mbps
5 GHz = 433 Mbps
On all devices with 2x2 on WiFi, the speeds above will be doubled on those.
These are in ideal network conditions with great signal strength and low interference. These numbers could reduce if you are far from the router.
This is not abnormal. A lot of mid-range devices only have 1x1 for WiFi.
