Is it possible to bypass a fritzbox wlan lock on the nintendo switch?
Does the internet of the box (router) go off or is the switch no longer permitted after a certain time?
Yes, unlock it again in the FritzBox.
I don't know, but can't you run it on your cell phone (hotspot)?
Without access to the configuration interface of the Fritz! Box no.
After a while, I can no longer connect
That's right, thank you
Then you have to go to the config of the box (think "fritz.box"), you need the password and you can then set it or delete it from the network, then you can reconnect and there's no longer any lock.
But remember, that doesn't last forever, the hotspot of your mobile phone runs over the mobile data connection, not over Wi-Fi. In other words, once your data volume is used up, there isn't much left.
This is only possible if you have the access data for the Fritz Box user interface. Otherwise you have bad cards.
