Recalbox 9 WLAN not working?

[ando]

I have some strange behaviour in Recalbox 9 on a Raspi 4.
The WLAN Settings say it is connected.
But the scraper does not return any results and Retroachievements say they could not communicate with Retroachievements.org
Any idea why this could be or how to test if the WLAN works?

@ando To check if the WLAN is connected, connect to the terminal and try these commands:

• ifconfig or ip a will show the configuration of all network adapters including what IP addresses they have

• ping -c 5 1.1.1.1 will test connectivity to the internet

• ping google.com will test that DNS lookups are working properly
