FP3 Android 10 WiFi 5Ghz unavailable

This brings me to this question: Is there an option in adb to select the Wifi band? I did some research but was not able to find anything.
If somebody knows about this, I would be happy if you could share your experience!

Hey, I’ve just updated to the latest FP3 Android stock firmware and afterwards the Wi-Fi Band Option was gone from the Advanced Wi-Fi preferences + I’ve had 2.4GHz selected before the update so this option was still acitve completely disabling 5GHz for me.

After multiple reboots and back and forth I figured a way to restore the Wi-Fi Band menu option.

  1. Push power button until the power/restart/screenshot menu appears
  2. Push (and keep pushing) the “Power-Off” Option until a dialog for “Safe Reboot” appears
  3. reboot into safe mode
  4. go into wi-fi preferences, advanced => WiFi Band should show up again
  5. Select 2.5ghz, then “Automatic”, then reboot
  6. verify that Wi-Fi Band option is now available again

Warning about Safe-Mode: This will reset your home screen widgets, potentially do a screenshot so you can configure your widgets again afterwards.

Update:

When you are in Safe-Mode, @Simon1 workaround also included:

  • Set back/reset the network settings (system=>advanced=>reset options=>reset WiFi, Bluetooth and mobile settings)
  • (dont know if necessarry) restore default settings in the developer options (last setting in the dev opt list) and disable the developer options afterwards.

Yeah, that works! Great workaround - thank you :slight_smile:

Update:
There’s a big BUT! After normal restarting I noticed that my audio player app widget was no longer on my homescreen. Soon afterwards I received a call from a number I recognized but the contact name didn’t show. After the call I checked my contacts app and nearly all my contact details were missing. Fortunately I manually synch them with my email account as soon as there’s an update to one of my contact’s details, so I was able to restore the lost information. Be aware of this!

Cool!

1st I thought it doesnt work for me!

But after the following two steps it worked:

  • Set back/reset the network settings (system=>advanced=>reset options=>reset WiFi, Bluetooth and mobile settings)
  • (dont know if necessarry) restore default settings in the developer options (last setting in the dev opt list) and disable the developer options afterwards.

@sydpol
The network reset should be added to your howto! THX a lot for your research!

@hypnotoad
Disappearing of some widgets after saveboot is normal.
I sync my contacts with the DAVx5 app to my own private nextcloud server and nothing was lost or had to be restored after the saveboot. I recommend this setup to everyone!

@Simon1 Did you do these steps in Safe-Mode as well?

@hypnotoad Here is the official Google documentation on Safe-Mode. Yes the Widgets are getting reset, the contacts problem shouldn’t appear and might have to do with some caching mechanism.

I was quite upset with the Wi-Fi issue appearing last night, glad I spent the time to register here and leave a comment. Have a nice New Year’s Eve everybody.

Thanks for the additional information! I wasn’t too concerned regarding the widget, but the contacts issue could have been rather frustrating :thinking:

Yes, the steps were made in savemode. And afterwards I had to restart in savemode again to get the select WiFi option.

Wish you a great new years eve, too!

Thanks! Reset Wifi in Safe-Mode worked for me.

I am baffled that I just found your solution some months after you posted it… It is working great, thank you very much!

Of course the widgets have to be done new, but that is not a problem.

I am doing the same; using DAVx5 with my own private server running nextcloud. But in my case after the saveboot: Contacts, calendars and tasks was empty without any content. Not a big deal, of course. Doing a new sync and everything was available again.
