OnePlus One OTA-11 Wifi issue

[th0mas]

Hello UT community,

I am a new owner of a used OnePlus One.
I have installed Ubuntu touch successfully.

Thanks to UBports for keeping this project alive.

I have a Wifi issue. The connection is low and keeps disconnecting and reconnecting.
Here is a dmesg log

I don't know if I need to flash a special modem file as in the Android ecosystem. I have tried several without success.

I don't have a SIM card inserted yet.

Thanks for your help.

Regards,

Thomas

Thanks for the help.
I have tried that, it is a little bit better but not very good.

I have also tried to install the latest LineageOS and the WIFI works flawlessly. So it is not a hardware issue.
Enabling only 2.4GHz Wifi does not help.
