My Modem = Motorolla Surfboard Sb6180...30mbps cable connection.
Everything seems to work properly if I eliminate the router and use direct connection.
When I don't, after a few minutes, my connection drops (though I see no change to the lights on the router (DIR655), but 2 of the lights from my modem disappear) and I have to plug off my modem and then back in again.
What is the problem? Not sure what other info you guys need, should I post a screenshot of my router setup page?
