I was wrong (and should have tried it before sending it). The command
should have been
route del -net 192.168.1.0 gw 192.168.1.1
and if you get something like "SIOCDELRT: Invalid argument" try
route del -net 192.168.1.0 netmask 255.255.255.0 gw 192.168.1.1
AND be sure to do this as root, not your normal user name.
You said in one of your earlier replies that the routes returned after
rebooting. This is most likely because the routes are setup by the DHCP
client on your PC from the response by your DHCP server (your router). I
have no direct experience with Linksys routers, but their user manual
shows some screens from which you might get some clues to your problems.
Look at the "Static Routing" section in the user manual, for example.
If you continue to have problems, you might post the output from the
commands
netstat -rn
cat /etc/sysconfig/network-scripts/ifcfg-eth0
cat /etc/sysconfig/network-scripts/ifup-routes
Good luck.
