5 Ghz WiFi does not work anymore? - Atrix 4G Q&A, Help & Troubleshooting

Hi,
I am no longer to scan any WiFi network in the 5Ghz band. I tried a few reboots. But still does not work. On the contrary, I can scan and connect to 2.4 Ghz channel without any issue.
I am running Epinter's CM 10 with Nov 17 build.
Any ideas??
Regards,
Anupam

[Q] Connecting to 5Ghz wifi

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?

Wifi Problems

Hello...Having updgraded to a 50 K connection , I noticed a problem with the Wifi of my OnePlus X. Numerous times a day, it drops from 40 to 48 k download rate to just 3 to 5 k. When I go to airplane mode, all is back to normal. I have a 2,4/5 GHz network running, and all other devices, wether they are on 2,4 or 5 GHz run perfectly smooth.
Any suggestions?
Try with this: FXR wifi fix and rescue
Tried FXR wifi fix...didnt fix my Problem. Thx for the tip though.
But it seems I fixed the problem for now. Tinkered around with Wifi channel settings and finally got the consistence in speed I was looking for.

5Ghz WiFi not working after updating to EMUI 9 (Pie)

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.

5GHz wifi not working on Redmi note 9 pro (indian)

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.
