I'm having some problems with Raspberry Pi 4... The wifi works normally when I use 1920 x 1080.
But when I change the resolution from 1920 x 1080 to 1280 x 720, the wifi suddenly disconnected and unable to connect...
At my wpa_supplicant.conf
, the update_config=1
I change it into update_config=0
nothing happens...
I tried to back to 1920 x 1080 to do the following task :
sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get dist-upgrade -y
sudo apt-get install rpi-update -y
sudo rpi-update
sudo apt-get purge rpi-update -y
sudo apt autoremove -y
and the wifi still works normally. But when I back to 1280 x 720 become disconnected and unable to connect to any wifi...
I Even try using: sudo systemctl enable networking
still no luck...
my current eeprom VL805 : up-to-date and version 137ab
But when I tried to return the resolution to 1920 x 1080 it works just fine...
But when I change the resolution to 1280 x 720 back to wifi disconnected...
Seems that there are wifi issues on Raspberry Pi 4 for wifi when changing resolution beside 1920 x 1080...
Any idea how to fix it?
PS : I use original raspberry micro hdmi cable and original raspberry charger.
