I need help with my linksys wireless router. One day it works, next it doesn't. It shows I am connected and all the IP adress and network is active, but cannot get online-not even to the router IP address. It says cable unplugged, but there is not. I have tried reset, unplugging the router and computer. It does not seem to be the computer, since I have gotten online with it elsewhere. My ISP will not help and says I will have to get a new router. It was working, then it;s not.
