I tried Cox support and they are very good at confirming that my hardware in windows is good, but they don't speak Linux.. I tried to look at the configuration values but couldn't see anything suspicious. If a config value is wrong I would expect that i wouldn't get Gmail.

Check the MTU.  The default is 1500 bytes, but some providers use a
smaller value (e.g., on a DSL connection running PPPoE, the MTU is
1492 bytes).  If the interface MTU is set to a value smaller than 1500
(left over from a DSL configuration?), packets from the cable modem
are probably being lost.
