Hello, I'd like to ask if there is a way to make Xperia P use 5GHz WiFi networks. I've tried setting my router to 5GHz band but sadly after doing that the network wasn't even visible for my phone. I've heard that Sony disabled it for the phones although the WiFi chip supports it, so maybe there is a way to enable it. I'm on custoMIUI rom with Phantom kernel now but I've tested others, stock based too, with no luck. Thanks in advance.

I previously disabled 5Ghz frequency from Settings - WIFI - Advanced as previously I only had a b/g WIFI
Now I have bought Asus dual band a/b/g/n router+access point but my phone cannot see the 5Ghz network. It can see and connect to 2.4Ghz
I tried to enable 5Ghz but that option is not showing in WIFI advanced settings anymore!!
I have already reset and flashed new samsung firmware but that option is still not there..
1. Is there anyway to check if my phone is using 5Ghz?
2. Is there any secret code to enabled wireless frequency?
Any help would be highly appreciated.

Bump. I just got a brand new sgs3 (was a sgnote user), for some reason my sgs3 can't see my home 5ghz. I tried to Google and search about this issue but came up empty. My now sold sgnote and my others gadgets laptops etc. don't have any problem with this. Currently I'm on stock DLI8 and did flashed other stock Firmware and no juice. 2.4ghz working great but I need 5ghz as I live in congested 2.4 neighborhood. Hoping some kind soul could enlighten me about this issue.
WIFI cannot see 5Ghz access point [FIXED]
For those owners whose device can't see wifi 5ghz frequency, your device is not broken which I thought mine was.
The remedy is simple, set your wifi country to EU, JP, or others same as your routers bands, as samsung default was set to US ( my router E4200 is APAC region ).
Use RootExplorer and SQLite editor ( these apps from the same dev ) and go to "/data/data/com.android.providers.settings/databases/settings.db" in "secure" table, look for "wifi_country_code=XX" change XX to JP as in my case. Reboot your wifi. Et voila ! There it is my 5GHZ SSID !! :good:

Hi, my i9300 can see the SSID of WiFi 5GHz and is able to connect to it successfully. But it cannot auto-connect to the SSID of WiFi5GHz when the WiFi is disable and then enable. or i9300 device is rebooted, or come back to the room with WiFi 5GHz. This issue doesn't happen on WiFi 2.4GHz.
Did you encounter this issue?

Great, my auto-connection problem is resolved after changing the wifi_country_code to JP, but when I reboot the device, the value of the wifi_country_code has been restored to the orginal value. How to finallized it?
Thank you very much, My phone suddenly stoped detecting all wifi routers, it couldnt detect anything, and when i changed the country to Japan, it could detect again.
Hello Together, I'm running the Xperia Ray on SE Stock Rom 4.0.4 with Sirkay's kernel 8.22 and realised a problem with the WIFI connection.
To expand the range of the network I installed a Fritz!Box 7390 (newest firmware) (base station) and connected a further 7270 Box in WDS mode with the same SSID and the same password.
Unfortunately the Ray doesn't switch automatically between both access points. It only switchs by disabling and enabling the WLAN in the menu.
Hansip87 wrote in his tutorial the WIFI Tweaks (Burstmode . . .) unfortunately they aren't available anymore in tiwlan.ini only the option for 2,4 and/or 5Ghz band.
Does anyone know how to force the ray to switch the access point if a stronger network is available? I tried the app WIFI jumper, but it doesn't work. Therefore I tought, the problem is caused by the settings of the ray.
Maybe someone can give me an adivice.
After upgrading to ICS 6.1.1.B.1.10 on my wife's new XPU had no issues except for the WIFI bug.
It refused to connect. So after a bit of trial and error here is the workaround I found and I am sharing just in case anyone else has the same issue.
1. Login to your WIFI router and change security to WEP with a shared key.
2. Set a key which is exactly 5 characters. a-z 0-9
3. Connect to wifi from your phone.
VIOLA!!! works. Its a major bug and sony should get this resolved soon.
But until then here is my simple workaround.
Switch router to b/g mode only (not n).
Use WPA2-PSK
--> Safer
Might as well not bother with security if you're using WEP.
Never had a single problem with my Xperia U and wifi on any firmware, using WPA2 and a 18 digit pass code.
I have never had wifi issues either, and my girl has an Xperia U too and same as me, perfect wi-fi.
Try to restart router if you can
My GF has the same problem, after the update to ICS (on the Xperia U) every time she tries to connect to WIFI it works for a few seconds and then it stops.
But that's not all, after that, nothing connects to the WIFI anymore, all active connections stop, the router sends data to LAN (wire) only,
I can't connect any device to the WIFI, I tried with my Galaxy S, Xperia S, even the laptop.
I have to restart the Router to have WiFi again.
Does anyone know a solution, except the dumb one to turn my router to b/g?
I have another router (old one WRT54GL) and it's not even working on this one. No connection, despite the fact that it's a b/g router.
Use Flashtool and put the .54 or c firmware on

Yeah, I flashed the C FW, works great so far.
My Xperia Tablet Z Wifi seems to be having issues connecting to only HIDDEN 5GHz band Wifi access points. If I unhide the SSID's, the Tablet Z will connect to them. Has anyone run into this issue? Is there a workaround? I have the Xperia Z LTE phone, and it connects to both 2.4GHz and 5GHz hidden SSID's just fine. The tablet is an SGP311 w/ JB 4.1.2. I'm pretty sure it isn't a router problem if my Z phone and other 5GHz devices don't have any issues connecting to the 5GHz hidden SSID. Any help and/or insight appreciated, thanks!
there is a way to connect to hidden networks. Tap + to add networks, enter network name (ssid) and password and it should connect to it even if it is hidden and is not shown in networks list.
Hi,
I have been using the C5 Ultra Duel E5533 for the last couple of days and run into this issue:
Although I have read that this device supports the 5Ghz WiFi Band (Sony official Whitepaper) I am not able to discover the 5Ghz WiFi network I have set at home.
This is even more bizarre , as on the first time I setup the WiFi network the 5Ghz network was visible in the network discovery list - I could even connect to this 5Ghz network. Suddenly, after connecting to another 2.4Ghz WiFi network, the 5Ghz one just disappeared and I can never see it again in my networks list ?!
Tried resetting the WiFi router but still I cannot see/discover the 5Ghz network.
I am running the original E5533 firmware as my region didn't yet receive the latest update.
It does support 5ghz. Can it detect any other 5ghz routers? Like your neighbour's? Or if u have other devices that can work on 5ghz. It could be the channels that your router is using that's causing the problem.
Did factory reset - it's OK now
