I got the linksys router problem which no problem

i got the linksys router problem which no problem at all when i connected to sg broad band . currently use it to connect to malaysia streamys broad band and problem occured. when i connect the router to modem and my computer, all the light on mode and router appear to be good. But my computer shows able to connect the router but not the internet. if my computer connect to the modem straight everything is fine and able to connect to internet. from my understanding there is no need for the router driver to install for the router to work. so far my computer is without route driver. when i enter 192.168.1.1 on browser to enter router setup page, everthing seem to be fine and at factory settings.
