The box works ok without the internetcable. As soon the cable is connected (even after resetting modem and linksys) the problem reoccurs.
I don't have any clue what makes you're linksys jump to diagnostic mode. Did you try you're internetconnection without the router? If this isn't working either (reset you're cablemodem to refresh the MAC address!), you should contact Multikabel about this...
