The AT&T router provides the wireless system, it is connected to my desktop using an ethernet cable, It works fine. We have wi-fi in the house. We need and use an extender for longer range, the problem I am having is securing the signal coming off the extender with a password. I am unable to find the administrators page to do that. When I initially set up the system a few months ago everything was fine, monday tech arrives and installs a new router , I plug the extender into the wall socket and everything works, I just can't find where to secure the signal with a password.. Following the linksys website and typing in the 192 number it directs me to websites and not the administrators page. They say use safari or whatever to do it but no luck, make any sense?
UPDATE:
After researching some more I found that my bonjour function was not enabled, once I did that i was able to see the extender signal/icon and adjust the settings. It is now password secure . Thanks to all who responded.
