Just to close this out - it's my gateway. I have AT&T internet service that looks like this: street -> cable -> gateway -> Amplifi router -> users the gateway includes a wireless router and a 4 port gigabit hub. I normally plug directly into the gateway so I don't share bandwidth with the kids in the house. When I cannot connect, I re-boot the gateway and it works for a while, but sooner or later it goes insane. But, if I connect to the amplifi router, it works 100%. Enough time lost...
