I have the SM-T713 which is the 8" 2016 version. I have a 25Mbps connection and every other wireless device I own, including 2 older Samsung tablets (a Tab S 10.5 and a 2014 Note 10.1) will consistently pull about 30 Mbps download speeds. My S2 have never even made it to 12 Mbps. Oddly, the upload speed is consistent with the other devices. Anyone else seen this problem? I am running stock Nougat 7.0 and use whatever defaults there are for wifi settings. All speed tests were run in the same location in my house. It's not a huge deal for me but I find it odd that such a nice tablet appears to have a wifi defect.
I also have the 8" SM-T713 running 7.0. I get 70Mbps and more on my 100Mbps connection at home, always comparable to my other devices. Have you tried different channels on your router?
No I have not but other devices using the same channel don't have a problem. I connected to my guest network which is on the 2.4Ghz band and the download was what it should be! I don't understand why that would be but since it works, I'll take it. Thanks!
I just received my T813 yesterday and its speed is slower than my original Tab S 8.4. I have 200 Mhz Comcast system. On 5. Ghz both my Samsung S8 and T700 are Faster.
T700 => 154 Mbps
S8 => 194 Mbps
T813 =>103 Mbps
Same problem with my T713. Maybe I'l try 2.4GHZ
What's reporting the download speed, the router or the end device?
I would only trust the router statistics.
Are the sources the same and reliable?
I'll have to run a speed check on mine, but I will say that my tab S2 is capable of better sustained network operations than my S7 Edge. I stream video from a NAS server to a Chromecast receiver via my Tab S2 flawlessly, which is something my S7 Edge can't do - despite the fact that the S7 has a "faster" network connection.
All of the devices are on a 5G WiFi network.

I just junked a netgear router with misbehaving wireless and nabbed a new one (Linksys WRT120N if you're curious) with N capability last night. I was hoping to get my SGT to connect at N speeds but unfortunately it keeps wanting to connect at G speed (54mbps). I've tried setting the router to N-only mode and the tablet still sees the AP, but it attempts to connect for a moment then goes back to scanning for APs. Yes, I've got great signal strength since I am sitting ~5 feet from the AP (the SGT icon shows full blue icon, my dbm is -34 for those of you that understand what it means).
Is the tablet's N capability disabled? I double checked the specs of my SCH-I800 on Verizon and Samsung's site and both say that the tablet has b/g/n wifi capability.
If you're nosy and want to know why in the world I'd even need N speeds, I have half a dozen computers in my house and some of them (thank you Microsoft) can't see the others for file transfers, so I copy the files over to my tablet from the source, then to the target. Not the best solution but I'd rather not toss up applications on all the computers and I haven't bothered buying equipment for a NAS device yet.
So... any revelations?

Dunno, I've got mine running on N just fine... Some of the lower end linksys routers have issues with N. You might look into dd-wrt and see if your router is compatible..

Pretty sure it only supports the 2.4ghz range of N. I could be wrong, but I doubt they would have included the 5ghz range of N wireless capabilities..

No, it supports 5Ghz range as well, just not all channels as I stated. My router is dual radio, and I have one SSID running at 2.4 and one SSID running at 5, and the Tab is connected to the 5 one.
It noticeably scans the 2.4 range before the 5 range, so first the 2.4 access points appear, and then the 5.
My personal experience was that I was able to achieve much much better download speeds by setting my router (WRT310N) to G mode only.
Before hand, when it was set to mixed I was getting speeds of like 1mbps download tops. Now I get 15+.

Would you mind mentioning 'some' of these channels so I don't have to manually go through all of them one by one to see if it'll work with my SGT?

I am facing a slow speed using wifi on the lumia 1520. For sure there is something wrong with the wireless card or the drivers.
1. The internet speed while connected to wireless that i get on the 1520 is half or even more less than what i get on my desktop (connected wirelessly) or on my other phones (both being android). I get a 25Mbps download & upload both on the computer as well as on both the android phones. But on the Lumia it will hardly even cross 10Mbps for download and 16 Mbps for upload.
The issue with the speed is really strange because if i connect the phone to a 2.4 Ghz network i get upto 10 Mbps download and 16 Mbps upload speed.But if i connect the phone to a 5 Ghz N network then the download speed i get is 0.67 Mbps and upload 14 Mbps. Whereas both my androids have a download and upload speed of 25 Mbps no matter whether connected to a 2.4 Ghz or 5 Ghz network.
I have changed different channels on the router and have almost everything including resetting the router as well as resetting the phone but no luck. The phone is OOB lumia black OS.
Any ideas anyone.
What router do you have? My internet speed is 55mb down and 6mb up. I get 56 to 58 down and 6 to 7 up on my phone. I have an Asus AC1900 router. This phone has been one of the better phones I have owned when it comes to WiFi speed.

I have a netgear wndr 3700v2 router . I was able to resolve the 0.67 Mbps speed issue on the 5Ghz N channel by enabling WMM on the 5 GHZ channel however still the speeds are half of what is the internet connection speed.
The surprising part is that after enabling WMM the speeds on the note 2 when connected to the 5 Ghz N channel reach the proper internet speed as on a wired ie:- 39 Mbps but on 1520 they hardly cross 15 Mbps download .On the note 2 or my other android as well as my desktop the download and upload speed is proper on both the channels 2.4 as well as 5 Ghz. This indicates tht the router is fine.
I think i have to contact nokia support to have this checked. I am not sure as to what else to apart from this.
Same issue on a N97, wifi is muuuuuuuuuuuuch slower than 3G. Some messages I got about certificates let me suspect the preinstalled Boingo appli. All worked fine on my previous 5730.
Hi
I have a dual band router, and i prefer to have as many devices on 5ghz, as it performs A LOT better in my apartment.
Of course i know that the chromecast is 2.4ghz only.
I have this issue: When i start something (netflix, youtube, deezer) from a device on the 5ghz network, it starts fine, but when the tablets go to idle mode, very often they stop seeing the chromecast and i lose control of the content playing (although it is still playing). This is not an issue if i run the tablets on 2.4ghz.
Any ideas?
May have set the tablet to to only use 2.4ghz when you are using the CC. Settings are under advance I think under WiFi.
I know with my phones in the house we have to limit it to 2.4 instead of 5ghz or we don't even see the CC since the our router has 2 separate ids for 2.4 & 5

That's weird, I have my 2.4 and 5Ghz networks with different SSIDs and I can see the Chromecast from either from both my tablet and Nexus phone regardless of which frequency they're on.
Really? Hmm with our moto maxx's and both RAZR M (all unlocked and rooted running newest firmware). When we have them in only 5ghz mode we can't see the CC
Are you sure the problem is actually related to using 5 GHz? I've seen the same problem on my 2.4 GHz devices - loss of connection to the Chromecast a few minutes after starting a stream, and difficulty of re-establishing it to control the stream. Maybe something else has changed, or you're just noticing the problem now.

Mines started doing it the last few days as well on 2.4ghz only, only some apps do it, youtube been one.
it's been my experience that CC can only be seen across 5 & 2.4GHz when channel width settings match across bands.
having said that, i've resorted to isolating the 2.4 band for CC traffic only, keeping all other devices (except tablet doing the mirroring) on the 5GHz band. ever since making the change, CC streaming has been relatively flawless.
It's probably a WiFI signal reception issue in general.
Case-in-point, I also have a dual-band router with different SSIDs on 2.4 GHz and 5 GHz APs (you really should use different SSIDs except in special cases).
When my phone has strong medium to signal, I have no problem using Chromecast while connected to 5 GHz. Phone sleeps, wakes, still connected.
However, I just moved my workstation to another room where 5 GHz is weak. 2.4 GHz is still strong (lower frequencies travel better), though.
With my phone on 5 GHz, control of Chromecast was sluggish. Chromecast's playback was fine because it's still getting good 2.4 GHz signal.
My phone went to sleep, and when it woke it "forgot" it was controlling Chromecast - in fact, it could not longer see any Chromecasts.
I switched over to the 2.4 GHz network and Chromecast was visible once more. I rather use 5 GHz on my phone and leave the 2.4 GHz band uncluttered, so I might have to relocate/reorient/reconfigure my router now...
When I'm streaming and tab casting from a laptop, I connect it to 5 and everything runs smoother because the data stream is divided over two frequencies. However I find that the Nexus 5 screen casting feature is not as content to operate if I'm connected to 5 GHz.

Hi all
I couldn’t find detail benchmarks of S5 implementation of Broadcom BCM4354 2x2 MIMO 5G WiFi 802.11ac module and in the end decided to take u plunge and purchased Asus ac68u router. Went thru setting up 5G ac wireless network and current results look like this:
S5 connects to 5G ac network with link speed of 866Mbps
File copy from:
Gigabit LAN wired PC to Routers attached USB 2.0 HDD 29MBps (240Mbps) - bottleneck usb 2.0 interface
5G ac WiFI S5 internal storage to Routers attached USB 2.0 HDD 11 MBps (90Mbps)
5G ac WiFI S5 sandisk 128GB microSD card to Routers attached USB 2.0 HDD 11 MBps (90 Mbps)
I have 100/100Mbps broadband internet connection and S5 on speed test performs as follows:
72Mbps DL / 75Mbps UL (same connection via wired PC benchmarks at 94Mbps DL / 95Mbps UL)
I haven’t managed to achieve transfers speeds above 100Mbps from or to S5 in any combination. Can you please share your experience of S5 wifi ac 5G network performance
Related : thread by xenokc about S5 performance on 802.11ac network
Thanks

can you test with no encryption? wep/wpa completely off.

Yes, i have tried that, but there was no change. Router firmware is upgraded to the latest version / wireless test were done in close proximity (1 meter) to the router without any physical obstacles between (clear line of sight)
I'm really on a mission to achieve transfers speed in a range of 350Mbps-400Mbs on local LAN (which should be doable) but i cannot get pas 100Mbps!!
i'll try to test as i know AC should be able to do it.

fffft said:
802.11 ac provides a theoretical maximum stream speed of 433 Mbps or 900 MB/s across eight streams. That is under ideal conditions - maximum signal strength, zero interference, zero processing overhead and zero packet overhead. Many router 802.11ac chipsets only support four streams and due to real life channel contention, you aren't likely to see more than two or three 160 Mhz channels chopping that maximum speed to about 250 MB/s. All of those speeds assume channel bonding and quite a few routers can't bond 80 Mhz channels cutting that speed in half again (125 MB/s). Then you have real world losses due to signal attenuation, antenna inefficiencies and interference.
The S5 was the first smartphone to support two MIMO streams. But two is not three, so lop another third off our speed figure (or lop two thirds off for the iPhone 6 which only supports one stream). You simply won't achieve your goal with the S5 or any other current smartphone. 350 Mbps is the upper end of the maximum speed you might expect to see from a high end MIMO PC card under ideal conditions in the same room.
In real life and through a wall, you should expect considerably slower transfers. And the type of traffic matters too e.g. TCP traffic overhead often reduces speeds three fold over UDP streams in router speed tests.

Thanks for detailed feedback, but then there is no benefit from implementing ac standard or 2 spatial streams suporrted by broadcom chipset when performance is comperable to WiFi n standard? But then again how did those guys here managed to pull of such results:
382MbpsDL
or
436Mbps
whit same hardware setup?
..
what kind of latency differences did you see between the wifi phone and your pc to the same server? i'm assuming speedtest.net or something like that?
This is strange as for my G900I I've been able to run an Internet speedtest at over 11 MBps (88mbps) over wifi on wireless N at my university which I imagine would have multiple connected devices. Wireless AC should be able to at least match the 88 mbps I had achieved.

No, don't do this. You must setup a WPA2 security encription to get maximum rates on WiFi N and AC.
Then, remove storage bottlenecks. Don't use a external HDD connected to a USB2 port. Much less on the same router, since USB performance is much lower on those devices. You will need to use 2 devices on the same LAN. One wired for maximum throughput tests. A ramdisk or a SSD on the host would help too, since HDDS are limited to 120-80Mb/s transfer speeds.
If you are going to use a file copy as measure, make sure you make it into the internal SD card of the phone, since external will be limited to around 8-12mb writes depending on the card quality.
To test networks you would need ramdisk to ramdisk copies, but I don't know how to setup this on android.
This is rather interesting to follow
iPerf is available on android.
Quick measurement gave me ~110-169 Mbits/sec using default values on 40mhz WiFi N 5ghz setup.

Thumbs up. Finding someone that uses IPERF for measuring proper network performance is golden. It irritates the heck out of me to find video's of people using ookla to measure their network speed, or like the OP, measuring against USB2. That's like measuring the speed of your new 600MB/s SSD installed on a SATA 1 controller and wondering why you are not seeing a significant improvement.
iperf is a little more complex than ookla though, and thats usually why. same reason most of us dont compile our own custom roms
really, there isn't much need to get over 100mbs on wifi for 90% of the public.

Just picked up the s5 because no store will sell me the note 4 retail price.
Linksys WRT1900ac stock firmware, 5Ghz a/c connected @ 300Mbit
From the phone to wired linux box @ 1000Mbit
187 Mbit up 207 Mbit down but of course it fluctuates. I don't use wifi for anything that requires that much bandwidth anyway, but I do get my full internet speed of 175/30 using the phone.
This post is rather old, but some of us may still be interested.
I was looking for an alternative to usb cable to transfer files fast between a pc and galaxy S5..
I've used a wifi-300 stick connected to usb port on PC: TL-wn821N, and configured my S5 as a mobile access point.
An ftp server is running on the phone and an ftp client on PC. i am accessing the AP via AirmoreAP hotspot, with wpa encryption.
I am watching the download rate via crystal internet meter for windows.
And this is the result: 64mbps/56 mbps (DL/UL) UL reading a microsd card on phone and writing to sata2 internal disk on pc.
I am wondering if I can reach much faster speed with a wifi-ac stick.
After recently upgrading my family's phone's, we all now have 5 Ghz Wi-Fi capable devices, so I got a dual band AC 5 Ghz Asus router.
My broadband is rated at 20mbps down...ok, so testing with ookla speed test I'm getting the same transfer rates on either of the Wi-Fi bands (2.4 Ghz or 5Ghz)
I thought I read somewhere 5 Ghz is what you want, and should select that one....but now I'm understanding it has much less range but more bandwidth, but if I'm maxing out my 20m connection at 2.4 Ghz, what is the advantage of 5 Ghz?
(I hope this makes sense to someone who can reply)
5ghz is better if you are struggling with 2.4. Depends on how many mouths you are feeding. If you speed test near 20mb then don't worry about it cause ur not drawing a lot.
BAD ASS NOTE 4
2 things
1. Set them up as 2 separate networks with different names as passwords. Thus prevents devices from auto switching
2. As a general principal 5.0 ghz I'd better for streaming media and gaming, but does not go through walls well. 2.5 ghz is what gives your router is range. So anything that is streaming (eg. Xbox, chromecast, pc) you want on 5 ghz and close to your router, anything else you want on 2.5 ghz so it will work at longer range without losing signal.
Sent from my SM-N910T using XDA Free mobile app
802.11n on 2.4GHz can connect at a minimum of 72Mbps and a maximum of 600Mbps. Unless you spent a boatload on a router and live in the middle of nowhere and operate no bluetooth devices you're unlikely to get 600Mbps on 2.4GHz as it relies on having four antennae and a 40MHz block available. 5.0GHz is much less congested so you'll always get the full 40MHz channel and the speed is limited by the number of antennae on your router.
The Note 4 supports 802.11ac, which skews it more heavily in favor of the 5GHz band. 802.11ac can use up to 160MHz channels which can achieve a data rate of 1300Mbps on the 5GHz band.
Now, all of that is completely theoretical. I can tell you that my T-Mobile Cellspot allowed me to hit ~80Mbps on 2.4 and ~130Mbps on 5 when I had a 130Mbps connection. I switched to Verizon and took 50Mbps due to cost, and the router they provide will only hit 50Mbps on the 5GHz band. On 2.4GHz I see closer to 25Mbps unfortunately.
Basically, I would set it up at 5GHz and walk to the extreme end of your house. See if you can still speedtest at your full line speed. If you can, stick to 5GHz. If you lose signal, drop to 2.4GHz.
Thanks for the answers guys.
