More router issues
Yesterday I switched routers: removed the Vigor, to be sent back to the supplier, and reinstalled the Fritzbox router of the ISP. However, intenet connection kept failing. Any access over wifi failed: though devices could connect to the router, an IP address was never supplied. That means the server could not reach the devices.
Today I found out the reason: the cable is broken, hopefully it is just a bad connector, because changing the cable is impossible.
There is another cable from the router to the network, that connects my TV to the swtich for that signal. For the time being I will use this link to connect the LAN to the router. It is not a big deal to miss TV on top, and replacing the faulty connection is simple, after which I will use it to reconnect my TV
