Wifi extender was working fine for two years. After the exterior ethernet cable was severed during a storm and reconnected it has not been able to reconnect to the router. I've tried all possible steps to connect the extender to my att router. Several factory resets and reboots for both the extender and router. I've added the mac address to the ip's mac exception list. It will not connect to the interenet. The steps in the forum haven't helped. Any suggestions or tips would be appreciated. I am streched already on my knowledge level around systems and servers. I feel like taking the extender outside with a hammer at this point.
