Linksys WRT54G2 V1 Router Blinking But Not Connecting?

I have a Linksys WRT54G2 V1 router that doesn't work. The lights all blink properly, but the internet connection part doesn't seem to be working. When connecting internet line directly to the computer, my internet works, but when connecting it to the router to the computer, it doesn't. I've tried resetting, unplugging for 30 minutes, etc. Putting in 192.168.1.1 brings up nothing on my web browser. Pinging it says connection timed out. My ipad is able to pick up the router signal as it shows the wifi bars on top, but when trying to use the internet, it says that it's not connected to the web.
