Lewis,
Sounds like it may be routing. Look at your routing table by entering
'route' at the command line of a terminal.
You should see several lines, the last of which is 'default' and should
have an IP address in the gateway column.
This tell the tcp/ip in your system where to go when it wants to connect
to the rest of the world.
If that is working, then perhaps you have a dns issue. In that case
enter this at the command line:
cat /etc/resolve.conf
This will tell you where your system is getting its DNS info. There are
(should be) IP addresses listed here.
If there are, try this command:
traceroute [ip address from the list]
This will tell you if you are able to reach your dns servers.
So -
If you do not have a default gateway in your routing table, then your
modem is not giving out that info. If you know the address of your
router you can manually add the gateway:
[as root] route add default gw [ip address of the router]
If your DNS tables are empty, then, once again, your router is not
feeding you what it should.
Regards,
David
