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.
My Xperia Z2 does not connect on 802.11n wifi, this is a bug in the firmware .402 ? I mean, the device finds the network but not connect! When I change to G / B, connect it back!

It happens in .438 based too. It used to connect to network by themselves, but not anymore. It happens with my friends Z1 too. So I think this is something wrong with wifi auto connect

Aussie .402 here and 2x Z2's working fine on 'N' - Auto connecting etc...
Sure its not your router or the channel?

The device does not connect automatically (based on location), and does not connect when I select "connect" the network that I want!

The channel is set to automatic, but I believe the problem is not that! Very strange... So I change to B or G, the smartphone connects smoothly! And there's nothing wrong with the router, since my Smart TV connects normally and Xbox ONE too!

I tried to tell you to turn off location based auto connect, it might solve the problem? I am in school and school is not allowing me to use phone on school time , so I can't try it now....
Also if you have got more than one router (or SSID) try to use only one AP... for example I am using multi router to cover my huge house in and sometime phone is not allowing me to connect to the network that I want, it connects to other AP.
Just in case I share my environment. I purchased Xperia Z2 from Australian Telco Telstra and I flashed RomAur 3.7. Stock Kernel.
My routers are using 2.4ghz and distance between 2routers are 12m. and I mainly use my phone in 1m away from router A(router that I want to use.)

Even disabling Auto Connect the device does not connect to the network "N". In "G" network connects smoothly! The modem / router has frequency of 2.4GHz, has something to do?
I also tried to change channels, but it still fails...

No more idea sorry mate. As soon as I find solution I will share with you. Till then you gotta connect to wifi with bg...... sorry about that.
I'm also having this issue. I have a dual band router with 2.4 and 5ghz simultaneous wifi networks and i doesn't connect properly or at all on the 5ghz network. I thought i was my router's fault.

My router has 2.4Ghz frequency ... it's very strange it do not connect!
Just sharing result. I tested with my 2router disabling location based auto connect, but it didn't connect automatically and not letting me to use the hot spot that I want to use. As it is not happening with my HTC One .
I think this is something wrong with software and we probably just have to wait.(maybe can send report to SOMC)

Dear All,
the phone sees the 2.4 Ghz wifi but not the 5 Ghz wifi anyway to solve this
regards
A lot of times this is router related. I have to set my channel width to either 40 or 20 in order for it to work. Be sure that you do not have it set to Auto or Mixed on your router.
Dear Globalrebel
Thanks for replying, I have already tried with auto & selecting each channels individually but still my phone doesn't see it, on the other hand I can see the 5Ghz wifi on the Iphone & on the note3
Regards
I'm not sure I have any suggestions for troubleshooting but I can see my 5Ghz WiFi at home and at work on my S6. At work I connected to the 5Ghz rather than the 2.4 and have not had any trouble with it.

Maybe you hided the 5Ghz SSID from broadcasting?
Try creating a new Wi-Fi connection on the S6 manually.

No, My SSID is not hidden and tried to add it manually still no success
any app to confirm if this is faut due to faulty hardware in the S6 edge?
Regards
Any possible way for S6 to see wifi 5Ghz channels 36 40 44 48?
regards
Same problem with S7
I have international version of S7 and I can't connect to 5GHz either.
Do you think that flashing a firmware from a different region can fix this.
Has anyone tried doing this?
I'm having trouble with keeping my Redmi Note 2 connected to home Wi-Fi. In the Wi-Fi menu, it often shows "Authentication problem". I am not experiencing this issue with any other Wi-Fi connection. Also, I have double checked to make sure the password is correct, and it definitely is not a password problem as it sometimes works.
I've even tried changing the password of my router, as well as the SSID (router wireless network name) to something else, thinking that it may have been a factor. Both methods did not help.
In addition to this, I am getting very poor reception at home for my data connection speeds. I don't think this is an issue with the phone though, as an iPhone 6S at home also has poor reception. However, I'm trying to figure out how to reset the network settings and I can't find it anywhere in the menus..
Would appreciate any assistance! Thanks.
More info.
What rom?
Which router, running which band?
Are you using n speeds, dual channels, single channel, wpa, wpa2 etc.
First thing I would try is set the router to G only (WPA_PSK). If that doesn't work, change the channel. Asus routers (the cheaper ones - e.g. NM10) can go coo coo bananas and fail to authenticate random devices, while others work just fine.
Try upgrading to the latest stable global xiaomi.eu rom. Get it here. Also, read the instructions how to flash there.

Sorry. Using SMIUI 7 by sebsch1991 (according to Settings -> About, based on 5.11.5).
I haven't fixed the problem yet.. but I realise that the Wi-Fi issue seems to "reset" itself after I restart. So whenever I notice that the Wi-Fi is no longer connecting, I just restart my Redmi Note 2 and it is able to connect again. Seems to occur in 24-hr loops?
I am using a D-Link DIR-865L. I have two bands (2.4GHz and 5.0GHz). Using the highest level of security I think? In my router settings, it shows I am using WPA/WPA2 (auto mode so it adapts to the device I believe). 802.11 mode is mixed (n, g and b).
The network settings issue I haven't found a fixed for yet, but to be honest haven't looked very far.. and I think it may be a telco issue.

When I first started trying out different ROMs, I found a few of them gave me WiFi issues with different networks. Some networks would behave normally, others wouldn't connect at all. I believe SMIUI was one of the ones that gave me trouble with at least one of the networks I use regularly, so I had to go with a different ROM.
I can't guarantee that you're having the same issue, but swapping ROMs is my best advice.
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.
---------- Post added at 10:55 AM ---------- Previous post was at 10:43 AM ----------
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.
