[Pi 4] - Issue with the integrated wifi after 12hours

[Flow]

Hello,

I've my new Pi4 since this week. I've successed to connect my pi to my wifi to do my server.

but it appears that after 12h, the integrated wifi go down and i have to reboot the Pi.

I've found some forum post from the past with the similar issue but without real solution (i.e. https://raspberrypi.stackexchange.com/q ... t-12-hours)

Is there a configuration file to change to keep my wifi alive ?

Thank you.

Did you run and apply rpi-update at anytime? If not You must then report if issue still exist.

Hi,

thx for the reply.

Unfortunatly, the rpi-update is not found either via command line, either via the apt get install command

I'm under ubuntu-server 19.10 raspi version.

I've updated the wifi firmware via : https://wiki.ubuntu.com/ARM/RaspberryPi ... 5#Packages

I've rebooted my PI4.

we'll see !
Thanks.

Run and apply rpi-update from Raspbian and reboot to apply the update. Then switch back to your Ubuntu SD card.
