Check to make sure you got the IP address and subnet mask correctly set.

Can you ping the gateway?

Firstly check out Elohim's suggestion (possibly try a different address incase its already in use somewhere), then i would move to the following

I would also check cable and switch port. It may be worth trying a laptop and plugging it directly into that interface with a cross over lead to se if thats ok. Also, check the duplex/speed on the interface and switches to make sure there are no mismatches.

Otherwise it may be a physical hardware fault.

Cheers

thanks for reply

hi,

Now i configure manually both side 10MBs it is working fine,
when i changed to 100 mbs it is not working
what could be the problem

pls give me aanyone knows

thanks

Make sure you have the same port speed and duplex mode set at both ends of the link, on the router and on the PC you have connected to it. If it still only works with both ends at 10 half then you have a physical problem; perhaps one of the network cards is faulty, maybe one of them isn't a fast ethernet card at all, or maybe your cable is faulty
