hey guys pls help me out.

i am jagdish from mumbai and i have hathway cable based inter connection
512 blastextra(7 GB).

i have win xp and hathway guys had set my lan card settings like this

IP : 116.72.29.113
Gateway : 116.72.16.5
Subnet : 255.255.252.0

it works absolutely fine when i have direct connection to PC.

i bought a wireless router (linksys wrt54g) to share internet
connection with my Laptops

when i try to set same settings in my router.
i get a error message which stops me from even saving
the settings to router

"IP address and gateway are not at same subnet mask"

which is true while ip has subnet as 29 the gate way has it as 15.

when i make the subnets of both ip add and gateway as 29 or 15 the
settings get saved but the internet does not work which is obvious
as i have changed the settings given by hathway.

Any techies around pls help me how shud
i set the given settings in this linksys router.

i also tried with automatic DHCP but internet does not works
regards
lalait
