No Internet on phone/tablet after update

Hello. After update my Router, i cant not use the internet from my phone and tablet.

what can i do, please help.

thanks.

@Heigregruck53

check that the router’s WLAN (Wi-Fi) is activated
disconnect the devices (phone, tablet, etc.) from the WLAN
then reconnect them

if this doesn’t solve the problem, reboot the router

on the other hand, the topic of discussion concerns the updating of Android TV boxes~

and has nothing to do with the router~
