  If I understand correctly, you can access machines on the local
network, but not the internet, right ? If so, then you might have a DNS
configuration problem. Normally the address of the DNS server(s) is
provided by the DHCP server (the Netgear router in your case) and is
kept in /etc/resolv.conf. Check if the content of /etc/resolv.conf is
the same as on the other machines on your local network.
  Another thing you might want to check is the default route taken by
your network packets. If you added a new interface (the wireless card),
perhaps now the default route is set to the wireless card and not to the
ethernet card. To see the routing table, run "route". The last line
should be something like:
default <address_of_Netgear_router> 0.0.0.0 UG 0 0 0 eth0
   The important thing here is "eth0" - the interface where packets are
sent to. This should be the same as the one given by ifconfig (which
has the IP 192.168.0.4).

Hope this helps,
Mihai
