My phone is no longer showing 5GHz WiFi networks.

Hello internet,

My phone is no longer showing 5GHz WiFi networks.

My phone is a Motorola Moto E5 running Android 8.0 Oreo. Even though it was previously able to show 5GHz networks it just stopped showing them, and I have no idea why. And can't see them even if use 3rd party apps; eg. WiFiMan and Wifi Analyzer.

Any ideas?

Welcome to the forums. Have you tried a reboot?

 

[QualifiedNoob346]

Hi there Golfdrlver97,

Yes I have tried rebooting the device. Still no 5GHz networks.

 

[Golfdriver97]

Did this happen after an OS update?

 

[QualifiedNoob346]

No. it didn't happen after an update.

 

[Golfdriver97]

Maybe this is an issue on the router side? Anything different happen there? an update, or maybe a need to reboot the router itself?

 

[QualifiedNoob346]

No, it applies to all 5GHz WiFi networks, not just my home network.

I'll admit, I'm at a loss for what to do. You could try a cache clear in recovery, or even a reset, but there is no guarantee either option will work.

A cache clear in recovery is the least intrusive, and nothing needs to be set up all over again like a reset.

Go to Settings>Wi-fi and go to its Advanced Settings. See if there's a Wi-Fi Frequency Band option to choose between 2.4 GHz, 5 GHz, or Automatic.

 

[QualifiedNoob346]

No. network frequency isn't there

Hmm. What options are there in the Advanced Wi-fi menu? Can you show us a screenshot?

Did you already try the cache partition wipe, as Golfdriver97 suggested? https://support.t-mobile.com/docs/DOC-38029

do you have wifi scanning enabled? it may only be detecting stronger 2.4 Gh networks and not 5Gh since they dont travel as well as 2.4..try disabling it...

Sorry it's been a while, I've been busy lately.
When I tried to wipe the cache partition (following the instructions on the T-Mobile site), I got to the part where you choose the wipe cache option. When I did that it showed the Moto boot screen, then showed this screen with an android, saying no command. I did wipe the casche in the storage settings though, but still no 5GHz WiFi.

I will attach the photos of the WiFi preferences as well.

Kind regards, Noob

The button press sequence for wiping the cache can be a bit tricky. Try the description I gave in this guide for the Nexus 7: http://forums.androidcentral.com/go...e-nexus-7-2012-2013-cache-partition-wipe.html
