When my router + Uverse gateway both restart after a power outage, I can't get to the WAN from the router or from LAN devices. A restart of the router brings the WAN up again.
I tried pinging IP addresses from the router and this fails. The log looks normal as far as I can tell. I tried restarting nmbd, but that didn't bring up the WAN.
I'm thinking that this may be a timing issue, e.g., router and Uverse gateway are starting simultaneously and the gateway gives out an IP address before it's actually up and running. Somehow, this causes a problem on the router.
I would appreciate any suggestions on what causes this or any ideas on how to diagnose further.
