5Ghz 802.11n not working? - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

I know the Galaxy Tab 10.1 is supposed to support 5Ghz 802.11n, but I'm not having any luck getting it to work with either an Airport Express or Linksys E4200
Has anyone else had trouble with this?

My guess is that it doesn't support it. I cannot connect to it either. Maybe a kernel mod can fix it.

Works fine with linksys

Works fine with my Netgear running DD-WRT.
WNDR3000 I think... Maybe 3100? I forget.

Anyone else have any input on this? I still haven't had any success getting it to work.

How do you have the SSID setup?
For 802.11n to function properly, you must use WPA2 with AES or no security (open).
Is that what you are running?
Also, make sure on the 5GHz side that the access point is using 40Mhz channel not 20Mhz.

Hi!
I've just bought Galaxy Tab 10.1.
I have the router Cisco Linksys E4200.
And I cannot connect to 5 GHz with my tablet.
Anyone succeeded to connect to 5 GHz with this router?
Thanks?

In Paris v4 and Pershoot's kernel. Using a Linksys e3000. Never had a problem connecting to either 2.4 or 5ghz.

Stock KME here, no problem connecting to a D-Link DIR-825's wireless N at 5.0 Ghz.
Must be something in your router settings....maybe check what the setting is on mixed data modes and all that stuff.

Hi!
It works now.
We have to set the Channel in the router config to get 5GHz working.
Here is the very interesting suggestion coming from Cisco Wireless Routers forum :
Set the 5 GHz band on the router to a only, 20 MHz and channel 36.
Wow!

wireless n
I think that the native 801n is O/S enabled. When i first got my IO tab it "saw" and connected to all networks a,b,g,n. Now after a boot loop issue and restore back to 3.0.1(from 3.1), I can only detect and connect to the 2.4GHz band of the router(which has separate simultaneous g/n capability)
If anyone has an apk to turn on the n for 3.0.1 i'd be greatful..
Fixed the previous post about the cisco(linksys) router settings worked..

Wifi 5.0Ghz
At my duaghters school she can only see/connect to the 5.0Ghz wifi in the lower bands/channels. I raised this with Samsung and their official response was that 5Ghz was not supported. See below. Its obviously not as absolute as thier statement as we are connect to some 5Ghz wifi routers - has anyone found the same.

[Q] Who got wifi "N" connection with the 101

Like the title says who got a working N connection with the 101. I can only connect at 54. Using a netgear WNDR3700 router and WPA2 AES
Maurice
I'm in the exact same position. My N1 and my eeePC both connect at speeds greater than 54mbps, but the A101 will not go any higher than 54mbps...
I was running a speedtest compare between my Evo and the 70i and noticed a big difference in speed, ~3Mb in favour of the Evo. Also noticed that its only connecting at g and not n. Is there some sort of governing going on?
are we talking connecting to an n router or connecting at n speeds?

Connecting at N speeds.
However, I did set my router to N only mode and I was unable to obtain an IP address.

does you router use 2.4Ghz or 5Ghz for n? what does the archos support?
My router is 2.4-2.5 ghz running DD-WRT. I checked the tech specs on Archos page but I don't see any info on what frequency they are using, just says it supports WiFi b/g/n.

The Archos is 2.4 GHz only. However that doesn't matter, because I have both 2.4 and 5 GHz on my netgear WNDR3700. All my other devices with N are connecting at N speed to it.
I think the problem is the wifi driver from the archos, unless someone can show me that he is connected at N speed with his archos.

i have a wndr3700 wireless router and using speedtest from the market i get
7.60 Mbps Down
3.41 Mbps Up
looks pretty fast N or not
I only have 5 GHZ N AP so I had to hook up a 2.4 GHZ "N" router that I have, but it is not really N, could never get 300Mbps connectoin on my laptop, but i get 54Mbps on the Archos, it seems fast enough to me.
not working
Very slow no N
I have 74 Mbit wireless connection with my 101 and an WRT320N-EU, so N does work in my situation

[Q] 5 Ghz WiFi enabled device?

Hello,
as I've read on the net, i9100 should be a dualband wifi device. 2.4 Ghz AND 5 Ghz ought to be supported.
I that true? Is someone actually using 5 Ghz-only mode or was that just marketing buzz?
greetings
No, it doesn´t connect to 5GHz WLAN
How could I control it ? I don't have anything related to it in my settings' panel ^^'

You are right! I just tried that, and it works just fine.
Thanks for your answers. But which one is correct?
Did you set your Wifi-AP to IEEE 802.11a which is 5Ghz or to 802.11n, which uses 2.4 AND 5 Ghz?
Please some more details. Right now the possibility for dualband is still just 66%
greetings
My case :
My house Router Setting - 2.4ghz band for Wireless G and 5ghz band for Wireless N... Both worked with my phone. But G on 2.4ghz more stable (most of the time 3bar or more), fot N on 5ghz sometime no network coverage.
My router : DLink Quadband DIR825
Sent from my GT-I9100 using XDA App
I'm using Apple's Time Capsule with both 5 Ghz N and 2.4 Ghz G and N.
As usual 5Ghz is faster but weaker in signal strength.

I tried to set my router to 5GHz mode, and it wouldn´t find the WLAN even if I´m standing next to the Router.
I only tried 802.11n, not 802.11a.
But as others said differently I may give it another try. My Firmware is still KE2, maybe the updated the WLAN-driver later?
I´d actually would like to be able to use 5GHz, as there are quite a few 2,4GHz WLANs next to me, so bandwidth isn´t always the best.
So, whats the case now? Are there several different Hardware/Softwarelayouts on the market or why are there these differences?
Can someone confirm that pure 5GHz wifi works or not, based on trial and error, and post his Firmware-details?
Greetings,
Fenrasa
EDIT:
i googled something VERY interesting:
[Firmware] I9100XXKG1 (Android 2.3.4) (05.07.2011) is supposed to be able to connect to 5GHz Wifis. Can someone try it out and confirm it?
Another poster to the thread wrote, that "KE2 and 7" ought to connect to 5GHz wifi as well.
SOURCE: --cant post link yet, need 8 posts ---
No people some ROM's supporting some NOT !!
Example: Stock Rom -supporting!
and LeoMar75 Rom Revolution
My EU device with KE7 ROM does connect to 5GHz on my WNDR3700 router. IIRC I had to make the SSID visible to make the original connection; once the connection was set up, I then reset the SSID to hidden.
Allright!
Samsung Galaxy S2 i9100 on I9100XXKE7 logged into my 5GHz Wifi. (Buildnummer GINGERBREAD.XWKE7)
Thank you all for your help!
Just a follow up question to this:
It appears the GS2 does have 5ghz support at least to some degree.
Is this 802.11a 5ghz, or 802.11n 5ghz, or both? And on a side-note, what's the fastest speed you've got it to negotiate with wifi? On my Galaxy S, even with 802.11n and 10 feet away from my router, I usually max out at 72 mbps.
It definitely supports 802.11n at 5 GHz, as that's how I connect to my home network. I have no idea how fast the link is -- never bothered to check.
Now that I'm at home, I just connected to my 5 GHz 802.11n, and the link speed reported by the SGS2 is 65 Mbps, the same speed I get connecting at 2.4 GHz. I'm sitting about 2 meters from my access point, and the 5 GHz signal strength is only "good", as opposed to "excellent" for the 2.4 GHz.

Interesting, thanks 3waygeek! Glad to hear 5Ghz appears to work with 802.11n.
*Bump*
Anyone else have any experience/input?
5ghz works here too, speeds seem to be faster( not that they matter on real life conditions) but signal ill always be weaker for 5ghz as it doesn't penetrate walls and such as well as 2.4
Sent from Samsung Galaxy S2 on TELUS.
I am quite confused about the statements here regarding the signal ranges of a....n..
can somebody have a look at "http://en.wikipedia.org/wiki/IEEE_802.11" they give the largest ranges for ...n signals. The only thing I can confirm is that yes, I can connect to all: a... and ...n..
Well it may be useful to gather a collection of working/not working stats together to find the best rom/kernel/modem combos.
NOT working (5GHz network not detected, Time Capsule with separate named 5GHz channel, picked up fine by Macbook Pro):
ROM: VillainROM 2.4.2
Kernel: 2.6.35.11 ninphetamine 2.0.5, and also 2.1.3
Modem: XXKG6
ROM: LeoMar75 2.6 - XXKH3
Kernel: 2.6.35.11 ninphetamine 2.1.3
Modem: XXKH3
well, for those who can't connect to 5Ghz band, try to adjust channel setting on your router may solve the problem.
My S2 only supports 36-48 channels currently, and I can't find any region option in the setting menu.
BTW, yes, the 5Ghz signaling strength is not as good as 2.4Ghz. However, the trasmission rate (or efficiency) is much better than 2.4Ghz due to less interfere.

[Q] HTC One won't connect to internet using 5ghz wifi

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?
Anyone have any ideas?

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.
Just got a black ATT HTC ONE, everything is great, but no connection to 5ghz network here either.
I have a Netgear WNDR3700 and just updated to the DD-WRT build 21676, and still no go...

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?

Correct. The 2.4 GHz network should travel further. Its all about that sweet sweet 5 GHz speed though! Mine connects to my Asus RT-AC66U router just fine.

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.

Could anybody please try? Turn off your router's 2 GHz and use 5 only.

My tablet is connected to 5 gigahertz exclusively and has never dropped the connection. You may want to take a look at your router's wifi settings.
I have a brand new Galaxy Tab S3 SM-T820 Wifi version, and I have two wireless routers in my home. One is a RavPower ND007, the other a DLink DIR-813. Both are dual band routers. On both, I have the 2.4 GHz network and 5 GHz networks names differently. Every other device in my home - including a number of Samsung devices - connects to all four networks with no problem.
However, my Galaxy Tab S3 does not. When connecting to the Rav, it shows "Connected, No Internet", and can't communicate at all. It won't even connect to the DIR-813 at all.
It connects flawlessly to the 2.4GHz networks on both routers.
Both of the routers, and the Tab, all have the latest available firmwares/updates.
So it's definitely the Tab S3, and definitely a 5GHz problem.
Not sure how to report this to Samsung, but I'm going to try...
defenitley YES, 5G problem...

Last Sunday I forgot to turn off Wifi 5G on my router and used my Tab S3.... Reconnect each 2 seconds... Super Quality, Thanks a lot to Samsung..
And just to clarify - 5G works with the same router and my Phone S8 perfectly, so it is NOT a rouoter issue...
I've been using 5G exclusively as our SSID is 5G specific and never had an issue with WiFi. Solid connection 100% of the time. Netgear Nighthawk X8 here.

Will try to install the latest update this weekend, without any modifications. If 5G still does not work, I will send the Tab to samsungs repair-center, as it still will be covered by warranty.
Either it is a problem with modem-driver or Hardware..
But nevertheless, this is the very first device showing up this problem with 5G.
If Samsung is not capable to solve, this will be my last product purchased from this brand...
I did send my Tab to Samsung repair center in Germany. Will receive it today, but I already know that they did not find any problem, all fine..
Well - but they did not give me a detailed test-report yet... So I dont know what and how they tested..
Will return the Tab to my local dealer for replacement..
I'd like to test with a different SM-T825...
Reading this I haven't seen that you've tried updating your router's firmware. If you haven't try that too. I'm not sure if when you say "install latest update" if that's the router or the tab.

Just by chance I found out, that 5G works if no SIM inserted. And IF SIM is inserted, it MUST be active. In flightmode and then activate WIFI does NOT work..
This is very suspicious... I hope that SOON we will find a working lineage for the galaxy tab S3...
Galaxy Tab S3 SM-T820 Wifi version and dual band 5ghz
Hmm, I just updated my modem as per better speeds from Comcast, but I also need a new router that would take advantage of the bandwidth and the 802.11ac dual band standard so that I can get to the 5ghz band.
I own a Galaxy Tab S3 SM-T820 WiFi and before I get a new router, I want to know if the WiFi adapter in the Tablet would pick up on the 5ghz band with a new router. Is there any type of updates or drivers or am I okay?
Thank you,
Jon
I'm on 5Ghz all the time. No issues.
Great news !!
I asked the question after I learned about the variety with routers and especially since I found out that my laptop's WiFi adapter only supports b,n,g and that I would need to buy a USB WiFI adapter for my laptop or somehow change the adapter chip inside my laptop to take advantage of the 802.11ac dual protocol.
Thank you, Jon
I have the t825 version, unfortunately I have problems with the 5 Ghz connection.

Hi, I have the T835 and I have the same problem. It disconnects 5 ghz, problem since I bought it.
Sorry, I'm wrong with thread

Galaxy S21 Wifi switching issue between 2.4GHz & 5Ghz wifi channels

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.

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

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.
Edit: Make sure to use the original MAC address of the mobile phone when log in.
