Can't connect to internet through router??

[Frederickson]

I recently had my router DC'd for awhile, now that i connected it back, any computer connected to the router, the internet doesn't work.

1. When wireless connections are connected it would say "Good" status
2. When a normal cable is connected it would say "limited connectivity" status

I thought it was the cable modem so i connected 1 computer directly to the modem and it worked perfectly, that's why i'm here right now.

On the cable modem lights, everything is the same,

Power, Recieve, Send, Online are all green with no blinks, the onmly blinking light is the PC/Activity, it keeps blinking orange. This happens in both conditions

What kind of connection is it? If its DSL through PPPoE, you'll need to configure your router to connect to your ISP through your modem, using a username & password. If the orange blinking light is on the modem, then the router is not properly communicating with the modem. Your problem most likely lies in the router, and not the computers connecting to it
