The weird thing is that my computer starts ARPing the router and never
stops.... The router only does some IGMP queries and replies, but
never answers the request.

Your computer should gather that 192.168.2.1 is your router's ethernet from the broadcasts it listens to. Thats also a way of learning ARP tables. However its odd that the router doesnt answer a specific ARP request targeted to him.

Now to the tricky questions. Where did you capture this? Maybe the router answered but your computer didnt get the answer because the switch in the middle is messed up or so?



No. Time Source Destination Protocol Info

I checked some logs during normal execution and the router sometimes
answers the ARP requests, but even when it doesn't my computer stops
making ARP requests probably due to the IGMP replies and queries.

I have attach the summed up log in this email.

Thank you for any help.
