Hey. Apologize for not speaking German. I have a problem for few hours already.

Router Speedport Smart 3 - only two lights ON - Status and WLAN. And there is no internet.

I restarted the router and reset it,but no result.

The diagnosis app on telekom.de is crashing. It says that the router is offline and the cables look to be ok. I have checked the cables - they are ok. When starting to restart the line during the diagnosis, the all process crashed few times due to error 503 (if i am not mistaken). Please help!
