You can ping your router -> IP works

If you can ping some outside machine _by numeric address_ then the
default gateway is correct. Try your DNS server.

If you can ping some outside machine _by name_ then DNS works.

Does #2 fail? What is your default gateway (as given by /sbin/route -n)?
Mine says

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.3.0 0.0.0.0 255.255.255.0 U 0 0 0 vmnet8
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.1.31 0.0.0.0 UG 0 0 0 eth0

I think the gateway is indicated by a "G" in the "Flags" column. Not sure
what happens if you have >1 gateways. Maybe then the kernel bases its
routing decision on the route's metric, packet's destination and
destination OR mask.
