Hi, while the router has been working for several months teh ISP is stating the new MAC address is causing the hickup. Setting the router to DHCP worked again. It showed me another IP address.
At fisrt the gave me the old address.

Thanks all.

Hello,

 

can you ping 82.176.143.254 from the router (has been asked before but I am not sure you have answered that positively)...
