Linksys WI-FI router WRT54G

[captainshailendra]

I had been using Linksys wi-fi router WRT54G for my home network. Suddenly I have found that now I can not access internet if I am using router but I can access all other computers in my network. If modem is connected directly to computer, I can access the internet.
Is there any problem with my router? How to check if the router is working fine. I have tried resetting the router but no result.
