My router supports 802.11n but my phones connect only in 54Mbps.
In addtion whenever i set my router to transmit only in 802.11n protocol , the phone can not connect to wifi.
it can see the router but it can not connect
The phone's chip always uses the highest possible compatible protocol.
All you can do is switch frequency between 2.4 and 5Ghz band. (I'd leave it on auto)
You may want to check with another non-similar Wireless-N router. In most cases i've seen this issue the Router wasn't actually N but one of the very early draft Versions (read: pre-beta) of the N-standard and thus had too many incompatibilites with the client for both to understand each other.
This would cause the device to go back to G standard.
ok, how do you stop it using "n". on my HTC I could tell it to use "g" to save power. On my S3, wlan traffic sucks the juice from the battery.
When I turn it to 5ghz band it doesn't find at all my router.my Samsung smart tv works fine with 802.11n , same with my ps 3 and my pc .My router is d link DSL 2740B

Mine connects at 72mbps on the default setting, check your router.
I download the application andromizer from the market and to the wifi settings I receive the message that my device does not support 802.11n set
I have XXLF5 stock root ROM

Any suggestion , i use all share a lot and all the HD videos are played with freezes
Guys i have tried many things but still i can not find any sollution .
Please can anybody help????????
my galaxy s connects to 802.11n network to 65Mbps , so i guess it is not my router problem. The strange thing is that the application andromizer says that my device does not support 802.11n set ups.Can somebody download the application and inform what result does he take ?

In addition when i set my router to transmit only to n protocol , my mobile find the network and try to connect but i get a certification error
Please answer the question/statement in the second post:

My phone connects with the router at 75Mbit/s. The router has a reduced late-draft-N protocol with only 2 antennas so it's correctly using the maximum capacity.
If you have the choice, please try e.g. with a N-supporting Fritzbox of the manufacturer AVM or other similar high-end products. Low-end cheap routers tend to have ****ty hardware.
My router is d link DSL 2740B, I think it is a quite good router with 2 antennas, but as I say my other devices connect fine in 802.11n transmition , my Samsung TV , my playstation 3 , even my galaxy s1 connect with 65Mbps.
Here is my router wifi settings, if you have any suggestions

hello,
i would like to know, how fast SGS3 can connect to my cisco e4200 n router that advertise 450mbps throughput ..
i'm trying to get 450mbps connection to my router..
on my router i setup wireless n and wireless bg network..
when i connect to 2.4g network i get 75mbps connection 1m away from router.
the same speed i get when i connect SGS3 to 5ghz network..
what i'm doing wrong?

I would think a major limitation would be because the wifi chip + antenna are SISO not MIMO. It could also be a compatibility issue between wireless chipset in the gt-i9300 and the router
Addition:
There are other special requirements to achieve 450Mbps too...

o.k. so is possible that i have something wrong with my cisco E4200 router..
so SGS3 have only single-stream ?
because my router for 450Mbps have to use all tree-streams..
thank to all for responding...
i will have to send an email to cisco...
now i will flash ddwrt firmware to see if is there any difference

As mentioned by xtechx, this is a chipset limitation. You'll just have to live with it since it only has a single antenna (meaning it supports about half of the maximum transmission speed of your router for Wireless N), as with most mobile wifi chipsets. Though if I remember correctly, the HTC One supports MIMO (full wifi speeds)

Old post but what the heck.
Wireless devices are built to operate at given speeds.
Common Android device connection speeds are 54Mbits/sec(802.11g), 65Mbits/sec, 72Mbits/sec, 150Mbits/sec(5GHz).
As WiFi is half-duplex, you will never see 'real' data throughput at the listed connection speed.
At very best, you'll probably only see ⅔ the connection speed.
The connection speed is often dictated by the number of antennas a device has and generally max'd out at 150Mbit/sec on 2.4GHz frequency due to 20MHz channel allocation limit, where 40MHz channel allocation is not encouraged.
5GHz frequency connection speeds are generally higher as 5GHz is based on 40MHz channel width.
I have a Sony XPERIA M (C1905) with dual band (2.4GHz/5GHz) WiFi.
5GHz has a connection speed of 150Mbits/sec.
Over 5GHz it has a bandwidth throughput of 109Mbits/sec in an optimal environment.
5GHz is a higher frequency than 2.4GHz so it will not have the same signal strength of 2.4GHz at distance.(trade-off)
If you really want to test WiFi throughput on an Android device, you have to use iPerf for Android and then install a Windows/linux version of iPerf on a NAS/PC.
This will provide true maximum bandwidth/throughput available to your Android device in a LAN where your testing servers should not bottleneck the Android device you are testing.
Because of the channel allocation, you have to have a 802.11ac router if your Android device supports 802.11ac to obtain the max. 802.11ac throughput.
Just got this phone today,
I have a Netgear R6300 capable of AC wifi but my phone wont connect to the internet when its on the 5ghz network. It works fine on the 2.5ghz but the other it connects but no internet.
I tried giving it a reserved ip and looking at the settings on my router but nothing is popping out at me?

Check the Advanced Wi-Fi settings. Check Freq Band and make sure it is not set to 2.4 GHz only. Also try turning on "Best Wi-Fi Performance" and see if that helps.
Mine connects to my 5GHz network with no problems at all.
Hope that helps.

What router do you have? Also what kind of connection speed are you getting?
I checked freq and it was on auto, tried just 5ghz, also tried Best wifi but it still cant connect to the internet. I gets a connection with the router according to the phone but my 6300 doesnt show it as a connected device.
no problem here i can connect to my 5Ghz network with my a/n capable Time Capsule router. speeds are 55..27 Mbps download / 35.95 Mbps upload. my One wifi settings are set to Auto (vs. setting to 2.5 or 5 Ghz).
I have a Netgear WNDR4500. Speeds are 40 Mbps down and 28 Mbps up. That is with the router 2 floors above me in my house. My settings are also set to "Auto" as well. I connected immediately when I got home on Thursday after getting the device. I have had no problems at all with WiFi. Sorry I cannot be of more assistance.
I have no problem when connecting to my R6300 in AC mode ...
mine connects just fine
No connection at 5ghz, can only connect at 2ghz
I have d-link dr-825 rev B router with [DD-WRT v24-sp2 (04/01/13) std - build 21153] firmware. It has dual 2ghz and 5ghz radios.
I can only connect at 2ghz and unable to connect at 5ghz.
I have a dell latitude laptop and my old Galaxy SII has no problem connecting.
Howvever Htc-One lists the access point, correctly determines what kind of security is on (like wpa/wpa2 etc) but is unable to connect. I think once I saw a brief flash saying authentication failure on my phone when trying to connect to 5ghz. So I removed all security and made it completely open just to try. Again no connection without any error.
I am thinking of returning it if it is going to be a problem.
---------- Post added at 12:17 PM ---------- Previous post was at 11:40 AM ----------
Ok, I have solved the problem, now it is connecting. I made two changes in the wirless setup. Enable RTS/CTS protection and also enabled short preamble. After these two changes it is connecting as expected.

I'm having the same issue with mine and the same router, can not quiet figure out what is going on.
Just quick update i just did an update on my router and it seems to connect completely fine
For those who have router issues, check for a firmware update! Most routers have a few updates while sitting on the shelf. I used to always update and properly configure routers (with out the software disc) for customers at my old job and we rarely had problems of customers bribing it back. And throw out the disc that comes with the router. The software can cause headaches down the road. All security settings can be done inside the router through any web browser and router IP.

Prefers 2.4
I have a dual band N router, and my One seems to "prefer" connecting to the 2.4 GHz network over the 5 GHz.
It will work fine on the 5GHz, but I have to switch it manually when I walk in the house (so I usually don't).
I guess I could just tell my phone to "forget" the 2.4 network to fix this. On more thinking, maybe it's a coverage thing - it probably finds the 2.4 GHz network first. Lower frequencies penetrate walls better, right?

You could always set it to 5ghz preferred. Mine connects to my netgear 5ghz ac router with no issues. Also if you have the same password for both frequencies it could just be connecting to that first.

I did check when sitting in my driveway - the 2.4 GHz network was still 2 "arcs" there & the 5 GHz was just a dot, so I think it is connecting to the first one it finds & sticking with it. In the Wi-Fi preferences, the "Wi-Fi frequency band" options are only Auto/5 GHz only/2.4 GHz only. No 'preferred' option - I'm running stock though - is there something different in the custom ROMs? I'm not afraid to root/ROM - I just haven't seen a good reason yet.

Use the only 5ghz only. There's a big difference with custom roms and stock att at the moment. There's new firmware etc. 2.4Ghz has more penetration through walls then 5Ghz. That's why you have more bars of one and not the other.

Well I want to be able to use the 2.4 GHz networks when available, so I'll leave it on auto. I guess the speed isn't a huge deal when the wireless connection is so much faster than my internet connection.
And yes, I know that there are lots of differences between stock & custom ROMs (my last phone was a Nexus S & I was always changing ROMs). What I meant to ask was if there was a difference with that specific option.
wifi 2.4GHz connection problems
Welcome
I have silver One for 3 weeks now, but it was 2 weeks in service - they reinstalled software and returned phone. No change.
I can't connect to any 2.4 Ghz network (G/N) ending Authentication Error. Only 5GHz works.
I tried it with Netgreat WNDR4700 (Gargoyle custom software), CISCO access point @ work, also random WiFi open networks in shops/malls, etc. Other devices i know and have at home ( Samsung Note II, htc Sensation, Acer Iconia tab, Dell Latitude laptop) works fine. Just the One cosing problems.
I run stock rom, how can I turn on more verbose logging or see what is happening in the Operation system while connecting? I must prove to Regenersis Poland service that my phone does not work. Otherwise they will say phone works within parameters.
Guys,
I have an Active but its probably the same for the regular S4.
I was just transferring a bunch of music files to my phone wirelessly and I was shocked how slow it was.
I just got under 2MB/s on a 72mbit link with WPA2 AES encryption.
I had full bars connecting to a Asus AC66U router.
I thought AC wifi is capable of almost gigabit speeds.
How do I see if my phone is using N or AC? Is there a way to force an AC connection.
Anyone else have the Asus AC router?
Can you post your speeds.
Thanks
Oli
Are you transferring to the internal memory or an sdcard.
Make sure you are actually connecting to the right access point. By default, the 2.4 and 5 GHz APs will have the same SSID, so just change one so they are different and always connect to the fast one.
On my rt-ac66u the 5GHz upload (file writing to NAS) speed is nearly 3x faster than the 2.4GHz from phone.

That depends on the Internet speed you pay for through your provider. The router can handle 1GB speeds.
Sent from my SPH-L720 using xda premium
It also depends on the speed of the phones processor and write speeds on the memory card whether it be internal or external. I have an AC66R and it connects at ac speeds I'm assuming. I haven't found a way to find out if it uses ac or something else.

Internet speed doesn't factor in since this is internal network transfer .
Storage write speed could be the factor if writing to a class 2 sdcard.
I have an net gear R6300 AC router and I used the es root explorer to copy files and I get about 9MB/s.. fluctuates a bit.

Are you sure they is no one else around you using the same channel?
I would have rather had usb3 than ac. Wireless is just not reliable when it comes to speed.
(Actually what I REALLY want is gigE. I have 8 drops around the house...could make it 16 if I bought a 16 port switch. That sounds be nice.)

I have the Asus AC router as well. Make sure you name your APs differently (e.g. add a 5G suffix to the 5GHz radio) The phone might connect to the 2.4GHz one otherwise. There is a way to force the phone to pick 5GHz APs, but requires an app/rooted phone:

If you have both networks passworded there is no way it can connect from the 5Ghz to the 2.4Ghz band. That's common sense. Do you take us for idiots? Mine always connects to "The G-Spot 5Ghz". The other network is "The G-Spot 2.4Ghz".

Your S4 will need to use the 5Ghz band for faster speed but it won't get anywhere near the claim of 1300Mbps. That only happens when you have at least three antennas to do MIMO for wifi and most likely a compatible wifi chipset. I am not sure how many antennas S4 has but you can use WiFi Analyzer to check the link speed. Link speed doesn't mean your actual real world transfer speed though.

That's what I have when I am connected at home as well. I can safely guess the S4 only has one antenna and 433Mb is the best it can do. For 2.4Ghz one should be able to do 150Mb but I never try. I didn't even try when I can connect to 5Ghz all around the house.
I have an issue with my galaxy S21 that is not automatically switching between my 5GHz & 2.4GHz wifi network when in close range to the router.
I have smart connect active on my router. When enabled, the 2.4GHz and 5GHz networks share the same network name and password(only one SSID will be displayed), and your wireless device will automatically switch connection to the Wi-Fi band that provides the fastest speed.
My device stays connected to the 2.4GHz network, I then have to turn my wifi off and back on again on my phone to connect to the faster 5GHz network when in range. My S21 is the only device on my network that does not do this automatically.
Anyome else experiencing the same or have a fix for this?

I've seen the same behavior. My configuration is the same as yours. I did a little experiment. I switched off the 5GHz range on the router. All clients switched to the 2.4 GHz range. Then I switched the 5GHz range on again. But even after 30 minutes, my 3 dual-channel android devices Galaxy S21, Galaxy Tab S4 and Galaxy S6 were still in the 2.4GHz range. Then I switched the S21 wlan off and on again. The s21 immediately connected to the 5GHz range and the other two devices followed immediately. Very strange. My WLAN router is a Fritz!Box 7590.
Otherwise, I know the behavior of the devices in that the devices only search for a new connection when the current connection is broken.
Sorry for my bad english, I am German.

Otherwise, I know the behavior of the devices in that the devices only search for a new connection when the current connection is broken.
Sorry for my bad english, I am German.

Thank you for your response. Samsung need to acknowledge this and apply a fix.

I have an issue with my galaxy S21 that is not automatically switching between my 5GHz & 2.4GHz wifi network when in close range to the router.
I have smart connect active on my router. When enabled, the 2.4GHz and 5GHz networks share the same network name and password(only one SSID will be displayed), and your wireless device will automatically switch connection to the Wi-Fi band that provides the fastest speed.
My device stays connected to the 2.4GHz network, I then have to turn my wifi off and back on again on my phone to connect to the faster 5GHz network when in range. My S21 is the only device on my network that does not do this automatically.
Anyome else experiencing the same or have a fix for this?

Hi! These are router problems. Set maximum power for 5GHz and average or minimum for 2.4GHz. Prioritize connecting devices to 5 GHz.

Can't be a router problem. Don't have an issue with any other device on the network switching between 2.4 & 5Ghz, only Samsung.

I see that a stronger signal is important for communication than fastest band. Samsung has a weaker Wi-Fi transceiver compared to a laptop for example. In my dual-band router, I made settings as described above.
The Android device alone can select the WiFi frequency range. Try to make the 5 GHz band more "palatable" to the cell phone by temporarily blocking the 2.4 GHz band in the router. Then remove the login data from the mobile phone and from the router. Make a restart from Handy. Then register the device again and release the 2.4 GHz band. Then test the behavior.
Please let us know if it helped.
