Very simple. On the back of your router there is a small round reset button. Use a pen and hold that button down for several seconds, unplug everything from the router, plug everything back in wait for it to come up again. Open new browser, type in the 192.168.1.1 put in your password and it comes up directly to linksys. Works for me everytime. For some reason when I have not gone to the 192.168.1.1 page for a long time it never works. I just reset my router and wallaw works like a charm.
Hope this helps. I had a heck of a time with this until linksys showed me how to do it.
