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.
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
Same ssid on 2.4ghz and 5ghz ..I want to connect to 5ghz ..but there is no band preference and it automatically connects to 2.4ghz.....
ANY SOLUTION???

bands r provided by networks if ur network
provides wifi over 5ghz thn it'll connect only
I'm using college wifi so I have no control over AP....the point is I want to prefer 5ghz band but there is no option for band preference.

..I have NO ACCESS to router ..I can't access the admin page and change the AP settings..I just want to disable the 2.4 GHz band of my smartphone so that it only connect at 5ghz as a client .like those redmi note 4 ...I tried with some apps but they didn't work...I think it's Oreo that's bothering..

hv u tried wifi analyzer app(green icon) from playstore??
this app can take u to admin page .. but to use 5ghz band u need to change AP Settings for ur wifi ip address for this u need username and pass of ur router..
I own the 8" LTE model (SHT-AL09) with stock ROM, unrooted and with locked bootloader. It originally had the EMUI 8 firmware SHT-AL09C636B196 (Oreo 8.0.0.196) but a few days ago I got an OTA and decided to upgrade it to the official EMUI 9 firmware SHT-AL09C636E2R1P2161 (Pie 9.0.1.161) and now 5Ghz WiFi networks don't work anymore.
Before the update, WiFi scan showed dozens of 5Ghz WiFi SSIDs in my area, including my own one, and I could connect to them without issues. Other apps such Wifi Analyzer also showed dozens of 5Ghz WiFi networks.
After the update, I can only see one distant 5Ghz network but not my own one. When I try to manually add my own 5Ghz SSID I got the error message "Unable to find MySSID".
It seems it is a hardware/system issue because Wifi Analyzer has also stopped showing all 5Ghz WiFi networks but one. I've used the mobile Hotspot feature of my other Android devices to rule out my router being the problem, but the issue persist. Needless to say other devices in my household (Android, WebOs, Laptop, ...) have no issues showing or connecting to my 5Ghz WiFi networks.
I can see many people having the same issue months ago when they updated their Honor phones, but so far nothing affecting the Mediapad.
Am I the only one with this issue? Any suggestion regarding what could I try to fix it?
Did you already try to change the channel on your router? Probably the channel you configured is no longer supported. This at least would explain why you can see other networks on 5GHz.

Thanks for the suggestion. I was using automatic channel. I've changed it to manual and tried several channels, but the result is still the same.
this exact issue happen to me (my son's Mediapad M5 Pro). just realized it today. tried resetting the tablet's network setting, connecting manually to the router 5G wifi. all to no avail. my other devices - 2 laptops, 2 mobile phones, 2 android boxes - all are connected to the router's 5G network without issue.

I read in Reddit some people manage to "fix" it by using a different channel in the router, as @AndDiSa suggested. Try setting the Wifi channel to manual an test different ranges of channel. Try first with the lower ones (36, 38, ...,46,48 ). If it doesn't work try with the highest range (149, ..., 155 ). If it still doesn't work, you can configure your router to use another region/country with differnt channels range until you find one that works.
same here, mediapad m5 8 (SHT-AL09), wifi 5ghz not work after upgrade to pie 9.0.1.161, I think this is bug. I'm using another huawei P20Pro and Honor Play, there are no issue about wifi 5ghz and connected to the same router
Please fix it Huawei
No WiFi issues here after I installed the OTA update to 9.0.1.160.
Does it seem to be a problem for the lte versions only? Is anyone with a wifi only tablet experiencing this problem?

I've a wifi only M5 8 - both 2.4 and 5GHz wifi is fine for me on Emui 9.
Same here. I own my M5 8.4 inch LTE version and I updated to Android Pie yesterday. I tried to factory reset for a couple of times and it didn't solve the problem. I think it's a bug of this firmware version hopefully it will be fixed soon.

Try changing the WiFi channel of your router. Lower channels did the trick for me

Yes, i tried that and it can connect to it. But it is very buggy. The connection drops a lot compared to my other devices that connect to the same 5Ghz SID. It is very noticable when playing head-to-head game such as Clash Royale when the bar is about 2 bars. It just drops off and switch to mobile. I have never experience the issue before emui 9 or on other devices.
:| I might have to drop back to 2.4Ghz.
Non LTE, not able to connect to 5GHz.
Suddenly able to connect on channel 40 after changing channels a few times, which is the channel it was on anyway. Weird.
Just to add to this, it connects at 5GHz but soon defaults to 2.4GHz.
Just updated my M5 8"LTE(C432) to Pie and no issues with 5Ghz Wi-Fi band works as usuall. Must mention that after all bigger update I start from 0 so I allways do a factory reset and start from scratch. This can solve many problems
After Upgraded, my Mediapad M5 only can see 5Ghz lower channel wifi (eg. Channel 60),cant detect upper channel ( eg. Channel 157)
hello, I upgraded to Pie this week (mediapad m5 pro LTE), after restarting the tablet 5 mhz networks did not see them, I made a network reset from settings, and rebooted the tablet, now works fine. sorry for my English.

Hello, after a few days that the tablet has worked well, it happens again that 5 mhz networks do not see them. I do a network reset again and it works again ... go pretty messy.
I have a WiFi only M5 10.8 inch device, and all was working fine until the OTA update. 5Ghz does connect to router but reports no Internet. Even though it reports this I can still browse using Chrome and can search for apps in the Play store but can't update or download any apps. I can use the same router on 2.4Ghz and everything is ok, so does look like a firmware issue.
"Great" job. As usual, from working device to buggy one.
How to disable update? I have WiFi only version and there is an option to auto-download update over WiFi, which I unchecked.

I'm using Redmi note 9 pro(indian) variant. MiUi global stable 12.0.5
Recently i bought a xiaomi duel band router and i have separated 5GHz and 2.4GHz band in the router setting.
But my redmi 9 pro is showing only the 2.4 GHz SSD. Though it worked on 5GHz for few hours.
***There's no problem in the router as my laptop and other devices are working fine in 5G band.
***** I have tried changing the region. *****
I tried to manually add the network SSID and password but it didn't work.
Then i have tried to change the channel in router setting. It didn't work either.
Did anyone have faced this problem and know any solution?
This is a bug in android 11, the temporary solution is first open the hotspot and the connect wifi , wifi connected then go to wifi setting and change 'dhcp ip' into 'static ip' and then turnoff hotspot.
