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.

Hi! I've replaced a router to Asus RT-N56U and my Photon can't see neither standard, nor 5GHz wi-fi networks. I have googled that the router may use higher channels of Wi Fi (12-13) while some devices only scan for channels 1-11. After I tried changing the channel from Auto to no. 5 - the network became visible right away.
I'm on stock 2.3.4 ROM currently. Is there any fix for WiFi module (drivers?) on MoPho so it scans channels 12 and 13?
Thanks in advance!
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
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.
Hi fellow xda members. I recently purchased the Samsung S9 Plus SM-G965F variant and in Wifi it cannot see the 5Ghz network that i have created. It will only detect the 2.4Ghz networks. I have installed the wifi-analyzer app as well but that also doesnt see it whereas my iphone can see it and connect to the 5ghz network without any issues. Ive been googling and searching this forum but couldnt find anyone having the same problem as me. I am not that experienced in android so dont know what could be the solution. Here are a few more details that might help
Baseband version: G965FXXU2BRG8
Build Number: R16NW.G965FXXU2BRGA
never mind....problem was with the router not broadcasting ssid on a greater channel range. Fixed it. Thread can be closed

I'm also havingthe same issue.it's definitely not a problem with the router..my every device can detect 5ghz wifi while s9 plus can't. ? ..
What to plz help..
Go to your wifi router settings and change the 5Ghz channel. Set it to one that is not too crowded (use the wifi analyser app) and that all your devices can connect. In my case the channel 157 solved my problem. I live in Canada and channel regulations can be different depending on each country laws.
Solved It

just put ur mobile on airplane mode than try to search for wifi, my note 10 plus can detect 5ghz wifi in this method.
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.
