[Q] 802.1n 5Gz - Galaxy Tab 2 Q&A, Help & Troubleshooting

Just picked up the tab last night and it is nice. I have 5 other android devices, and two laptops that operate on my Linksys E3200 on 802.11n at 5Ghz. The Galaxy Tab 2 7" does not see the access point. If I stand up a 2.4Ghz router the tab picks it up. The problem is 2.4 in our neck of the woods is plagued with interference. I called Samsung and they think it should support 5Ghz. Can anyone confirm that it does?

I tried a 5ghz open connection and my tab did not see it.

If a device's wifi spec is listed as 802.11 abgn, then it supports dual 2.4/5GHz. If spec says 802.11 bgn, then it's 2.4GHz only.
GT 2 series doesn't have dual-band wifi. AFAIK, no 2nd-gen wifi Android tablet to date supports dual-band.

Thanks for the response. It is listed as b/g/n not a/b/g/n. I have a xoom that supports this, and it looks like the xoom 2 supports it as well. Perhaps cause these are more budget minded tablets?

Does not see my 5GHz either, just the 2.4, 7" Tab2 here.

P5100 a/b/g/n - Can't see my home 5Ghz network

The specs indicate that the Galaxy Tab 2 10.1 has a/b/g/n capability.
Why is it that mine doesn't see my home N (5Ghz) network? (the router is broadcasting the SSID and I can connect with other devices)
Anyone else experience this? or know the reasoning?
Thanks.
Why don't you try to change that wifi router?

802.11 N can use 2.4 Ghz and 5 Ghz (depend on hardware spec), and usually 5 Ghz spectrum are used in some high end / outdoor router. Almost all smartphone and handheld device use standard 2.4 Ghz, so you can set your router to use 2.4 Ghz and "n" network.

Ah.. I see. This must be it. My network is certainly set to 5Ghz. It's interesting to note that my older Atrix can see the 5Ghz network, but the Tab 2 cannot.

its because 5ghz was thought to be the next band standard but it didnt catch on as intended

[Q] Does the galaxy note 10.1 have 5ghz wifi?

Hi, most reviews I've read online says it has 5ghz wifi, but I can't connect to my router via 5ghz wifi. The online manual downloaded from samsung Canada's website also says there is 5ghz (on pg. 101). My note 10.1 can't even see 5ghz wifi ssid. I know that my 5ghz wifi is working good because both my Acer laptop and LG O4X can connect to the 5ghz wifi. Is 5ghz wifi only available on certain models? I have GT-N8010 32gb wifi only model from Canada.
Yes all models have 5ghz not tested it though may be some issues with the settings
FWIW, I can see my 5GHz 802.11n router at home, but sometimes the detection is sporadic.
I can't see 5ghz wifi at all on my note 10.1. I even tried setting it up manually and it just says not in range. Is there some setting on my note 10.1 to turn on 5ghz wifi or is it broken?
5ghz is a relatively new technology I do not see there being any specific setting for that like I said never used but to there are couple of things you can try switch only 5ghz band on ur router and try setting it up close to the router and the band has one draw back and that is the range of signals.
Can you connect any other device on 5ghz and have to tried to connect it to another router with 5ghz bandwidth
5 GHZ Wifi
I am using 5GHz Wifi on my Note 10.1.....
i have an ac66r and have no problems connecting. the range sucks though. it also doesnt give me the extra speed boost i see on my laptop. the laptop only has n150.
My router is working fine. I'm able to connect to 5 ghz wifi with my laptop and my LG Optimus 4x. The signal is strong on both. I tried putting my note 10.1 without any case beside the router and still no 5 ghz wifi. I can connect to 2.4 ghz wifi fine. Any ideas on how to fix it?

Try changing the channel the router is using. Have you flashed firmware from a different region? Because some countries use different wifi channels than others.
I'm on stock rom, not rooted and haven't flashed with any other rom. It looks like that my 5ghz wifi is on channel 149. What 5ghz wifi channels can the note 10.1 use?
According to http://en.m.wikipedia.org/wiki/List_of_WLAN_channels that channels should be fine. Must be some other problem then.

I live in the USA and have a GT-N8013. The 5GHz wi-fi worked day 1, right out the box. I didn't have to do any special setup. Yesterday I upgraded to JB and it's still working fine.
My router's 5GHz access point is set to use WPA2-PSK [AES] with channel 153. I changed to that channel based on a recommendation from the Wi-fi Analyzer app. It wasn't necessary to change the default channel used by my router in order for the Note to see the AP or connect.
Maybe your Note is defective?
Is there a test to determine if it's a hardware issue? My 2.4 ghz wifi works fine. Are the 2.4 and 5 ghz wifi on separate wifi cards?

It actually predates 2.4GHz WiFi.
i use channels 44 + 48. decided on these when my GS2 failed to find the higher channels.
so it is probably limited like the phones to use the more common ranges.

Find some one with another 5ghz wifi network and if your note see it then the problem is your router. If it doesn't see it either then try a factory reset. Ultimately return for warranty.

Ya 802.11a was 5ghz.
5Ghz
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.

As long as i know, only the 8013 model can use 5 gz... as i read in Htcmania, a site from Spain.
"Modelo GT-N8013, es solo WIFI pero opera en dos bandas las de 2´4 Ghz (España, China...) y las de 5 Ghz (paises de países Arabe´s, de EE.UU...)"
Translate: model gt 8013 only wifi but operates in two ranges: 2.4 gz ( Spain, China, etc) and 5 gz ( for arabs countries Usa, etc.)
My Note 10.1 has actually done better on my 5Ghz network. On the 2.4Ghz network I was getting weird disconnects, inability to route traffic even though it showed connected, etc. Now that I'm on the 5Ghz side, I have not had a single problem in about 3-4 weeks.

[Q] Anyone using Wi-FI 802.n @ 40mhz ?

I was attempting a file transfer between my NAS and Phone today, but realised that despite the Nexus 5 supposedly supporting 20/40mhz bands on wireless N, I was instead negotiating with my AP at only 72mbps.
I have a Asus RT-N16 router running Tomato USB and my other devices can connect at 300mbps fine, but there is something about my Nexus that won't. Even though I think its suppose too.
Now this is separate to 802.11AC, my router doesn't support this and AFAIK it may work fine compared to 802.11n.
So my question is, has anyone else managed to get 300mbps N link speeds on their device when using a 802.11n network spec @ 40mhz?
Seems for some reason my device is telling the AP that it supports single band 20mhz only and is defaulting to this low connection link.
I have tried different WiFi tweaks, switching too and from mobile data modes after some research on here and none of it helps, still stuck at 72mbps.

My D2VZW is connected to my 802.11ac only 5GHz band. Does the S3 support 802.11ac?

I just recently bought a used Netgear r6300v2 router, and I put DD-WRT on it. I have my 5GHz band set up so that it is 802.11ac only. My S3 still sees it and connects to it though. It is only at a link speed of 150Mbps though, but I'm surprised it's even able to connect. So my question is, "Does the Galaxy S3 support the 802.11ac protocol, or is something else going on?" I'm using the latest CM12.1 nightly.
EDIT: Never mind, I just checked my router config again. Turns out that I forgot to put my 5GHz band back to AC only after updating to the latest DD-WRT build. Could have swore I did though.

5Ghz Wifi not detecting

Hi I got realme 5 pro 8gb variant 2 days ago as per specs it supports dual-band wifi 5ghz but it is not detecting my 5ghz wifi from the router. can someone please help me with this?
I tried to change the channel but in vain. That 5ghz wifi is shown on my laptop but not on phone.
Almost the same happens with my Realme Q. When I share hotspot on 2.4 GHz every device detects it and is able to connect. When I share 5 GHz mobile devices won't see it neither does my old Desktop PC that has wifi adapter.

Yeah its really sad for me because i got a new 5Ghz Router then i thought my internet will be stable as there are many 2.4Ghz wifi devices in my neighborhood so i decided to move to dual-band to get rid of disconnections and unstable speed

I think the issue has something to do with antenna of the device and which bands does it support. Perhaps? I'm sure they use different bands in china and different lte/4g/wifi technologies there than someplace else, other countries in the world.
Hello All,
I have Realme X2 Pro. I can connect to my 5GHz home wifi. But I am not able to create a 5GHz hotspot from the phone ....very frustrating.
I got a realme 5 pro 8gb and it its detecting my 5ghz wifi
Check and try change your Channel WIFI 5G and Setting Region...some region can accesss Limit Channel WIFI...I have same Problem but now Detect after Change my Channel WIFI 5G.
my R5Pro have the same problem, but when i change settings channel at my dlink router, the problem is solved. I change to chanel 149.
