SGS2 on 5GHz wifi

I recently got a new Airport Extreme Apple router [MD031LL/A] and wanted to know if the SGS2 can operate on the 5GHz WIFI frequency?
This router has both 2.4 and 5GHz frequencies.
thanks

Yep, mine can connect to my 5GHz wifi no problem.

Yes the SGS2 has a 5GHz Wi-Fi radio, and it worked for me with v2.3.3 of gingerbread, but since flashing any v2.3.4 it has not worked, though the 2.4GHz radio works in both versions.

Awesome!, but how do I set the sgs2 to pick up the 5ghz frequency?
It is turned ON on the airport extreme, but I don't see the SSID name associated with the 5ghz listed on the sgs2.
thanks

you shouldn't have to do anything, should just find it. I do find however the 5GHz band doesn't go through brick walls as well as 2.4GHz! so make sure your in the same room.

Based on your signature, you are using v2.3.4 of gingerbread, which like I said may not work.

Is there a solution to turn on support of 5GHz on SGS2?
Router works fine, notebook recieves 5GHz, sgs2 just don't see SSID. No difference between Auto mode and 5GHz.

As I said, no difference between variants on your screenshot, my sgs2 searches only for 2,4GHz networks. Looks like 5GHz option is locked on devices for some countries

Networking problem, need help please

Help,please.
Meet the problem. Transformer connected to my home wifi network. All devices in network connected to the internet, except Transformer. Manually configured network. I tried different wifi networks. All wifi networks successfully connected, but without internet. It looks like transformer could not route. i could not ping machines in the same network. Is there anybody who has same problem??
Thanks in advance
P.S. Who knows how to make routing table? Transformer connects to wifi, can ping himself but could not ping gateway in the same network.
It happend when i started playing with ROMs. Installed different ROMs with super wipe (Revolver, Revolution HD, Megatron, ICS WW_epaduser9_2_1_24, same problem.

have you tried switching the router off for a few minutes and rebooting it?

O yess, many times. If it is router problem, then all other machines could not connect to internet over wifi. Only Transformer could not, and tested on 3 different wifi networks (with and without DHCP)

probably wont help, but what about Kernel - have you tried different Kernels?

I tried different kernels, (Kernel-ICS-V22.6-OC1700-fb-AOKP_646, kernel_asus_rev01) but what kernel would you suggest?

if those have not worked then i doubt any others will. Rev3 Harmony (asus or universal) depending on which base your going to try - or the latest Guevor, version depending on base again.
Wifi is not my thing but thought id ask the obvious just incase. sorry i cant help more but im sure someone will be along soon :good:

WTF.
Installed Kernel Guevor N22.6 and Revolver 4.0.3 ROM. Same problem. Connected to wifi but no internet.
Even I disassemble Transformer and reconnected batteries. Does not help
Is it possible that hardware problem in wifi? Why in that case wifi connected? Magic.

First try turning air plane mode on then off to see if that works also your network may not like androids long default host name so consider changing that if you have root

What router are you using? make sure your using channels 1-11 (not 12 or 13) and check your on 2.4 GHz not 5 GHz

For the present test im using connectify soft and share my internet over my laptop. And it worked before. I installed busybox and did some commands. It looks like oruting table is correct, def gateway is pinging, interface is up. But could not connect to any site over integrated brower, could not connect to youtube or playmarket or gmail. Attached is screenshot. Maybe i lost something.

:crying:
No one, who can give me any advice??
I reflashed Transformer up to latest ICS WW 9.2.1.27. Did not help. Still connected to wifi, but could not access to internet.

giving your router configuration and brands, could help I think...
in my period of owning a transformer, there are one place at where I live where it can't connect to.. a free wifi at a restaurant.. it just cant't, it detects but it can't connect.. the channel was within 1-11, but still not connectable.. I've tried different roms and kernel, still to no avail.. while my other device can connect to it just fine... maybe there are some router that transformer not compatible with..

Problem is that transformer could connect to wifi network without any problem. It shows that connected to internet, but could not open any site or youtube or gmail.

"keep wifi on during sleep" set to always by default and i don't see anything else.

Have you used the same SSID on your 5GHz as on your 2.4GHz?
If so: they must be different!

My Note 3 Work very well on 5 Ghz, is my wifi at home. Router Belkin.
Look whit Wifi Analyzer, option wifi channels. You see all of the 2,4 Ghz, and if You touch on top left it change to 5 Ghz. You must see Yours.

My N9005 connects to my Asus RT-AC66U, but keeps complaining about an unstable internet connection. My old SIII worked fine. Compatibility issue between N9005 and Asus AP's?

Did you find a solution? I have the same pproblem.This plus the unstable connection problem is making me miss my note 1

Found this link http://forum.xda-developers.com/showthread.php?t=1675547 on 5ghz connection issues on Note 1 in Hong Kong. It describes channel limitation based on region. The file in my etc folder has ccode=GB which I assume is Great Britain. However, it allows the channels that my wifi router EA4500 is using on the 5ghz channel. So no luck on recognizing the 5 ghz network still.
I downloaed wifi analyzer and looked at my network. By default my router and I assume all the ones in my neighborhood use channel 1 on 2.4ghz. I just switched to channel 12 and there hasn't been any issue for the past hour i.e. no unstable connection warning from the phone. Just downloaded a 40MB file without any glitches at good speed. Will report back if the problem comes back.
Edit: Spoke too soon. Unstable connection warning back in a couple of hours. The interesting thing is that both my old Note 1 (N7000) and my wife's S4 can see and connect to the 5ghz SSID just fine and of course have no unstable connection notifications which seem to be an 'enhancement' in the note 3! Sigh Haven't even rooted the N9005 because of the knox flag or I would have played a bit with the wlan configs in the etc folder. Guess will have to wait for Samsung to come around to admitting a problem and then fixing it.

I've been having the same issue with my RT-AC66U.
Sent from my SM-P600 using XDA Premium HD app

I also have a RT-AC66U... and I'm connected fine with my Note 3.
go into your wifi settings and make sure that the third checkbox is not checked.
Name in french of this box is "Basculement réseau auto"...
With this setting enabled, my wifi is unstable even if the signal power is full.
Also make sure that you have the latest firmware on your router.

Try channel 48. Dont use those channels 160+, may not be supported.
I'm using an AC66U.

Thanks, I had same problem with my Note 3 not finding 5ghz and switching the 5ghz channel to 48 did the trick.

Droid Turbo 2 WiFi problems

Is anyone having an issue where WiFi disconnects on its own and seems to disconnect the phone from Verizon's network as well.

I haven't had that problem. I only had a problem with the advanced calling feature turned on during a call.

I did where the phone showed still connected but router showed disconnected. It is not a phone issue, it was an issue with my Linksys N router

What was the issue with the router causing this? Did you fix it?
Thanks!

It seems to be a problem on both the Turbo and the Moto x pure, many people in the Motorola forums say they purchased a new router and it seemed to work. I personally won't be buying a new router just for this phone. Hopefully it will be fixed with the marshmallow update

Well I disconnected my Linksys Router and used the Comcast modem and setup WiFi with it and works great now

extremely frustrated with turbo 2 wifi
I'm having the same problem, and it's true on at least 3 different routers so far. I surely won't be replacing every router I ever need to connect to. As a frequent international traveler this is a HUGE problem for me and will result in my getting a different phone before my next international trip if it is not resolved quickly.

Are they all linksys

No. Haven't tested on any Linksys. All were Netgear routers, 2 with N (running DDWRT) and one with AC (factory firmware) protocol.

Don't know then. Mine has worked fine on a netgear R7000 on stock and dd-wrt.

Question: Are others who are having this problem on open networks because I share am open network with other people who live at my residence and I don't have this problem when I am visiting my friend who has a secured WiFi connection.

Which channel are you using at 5ghz?
I had the problem with my huawei and now with my op5 with channels higher 100.
Try a lower channel - like me at the moment 36. Perfect for all my devices.

still having same issue . Currently i am using Xiaomi router 3 .

Mhh, you can try: Settings -> Backup & Reset and selecting the Network Settings reset option. This will lead to your OnePlus 5 forgetting all Wi-Fi and paired Bluetooth devices.
After resetting the network settings, reboot your 5 and then try again. If this not fix your problems I don't know.

i dnt know whats wrong tried a lot but doesn't working

I got this probleme on my samsung s tablet with France region software. Il look like the 144 and up wifi channels are only in us and some international devices ignore them. So I put a lower wifi channel 56 i think and it worked.

If you're using Magisk. You could check out (my) Magisk mod https://forum.xda-developers.com/apps/magisk/magisk-oneplus-5ghz-mod-t3656016 it changes the wifi region to 'EU'. I can see and connect to channel 149 for example with this mod.

OnePlus seems to have buggy 5G wifi support, this configuration works on mt OnePlus 5T: Band: 36 (5.180 GHz), Width: 80 Mhz, SideBand: Lower

My problem with 5Ghz wifi is slightly different. While it shows very nice download speed (260-300Mb), the upload is barely reaching 1Mb (while me standing 1 meter away from the router). It's not impossible to upload a photo to cloud or have a call over Viber for example. I tried this and it didn't work:
Resetting all networks settings and rebooting the device
Doing factory reset. I actually rooted my phone without a full backup lately.
My observation: phone shows very nice speed on 5Ghz WiFi without the SIM or when SIM data is switched off. Looks like OP5 modem messes the WiFi connection somehow when mobile data (4G) steps in.
My router is Xiaomi 4A Gigabit edition, by the way.
Did anyone face the same?

it work for me when change channel to 36 (36-48 worked fine)
