Why am I unable to connect to a broadband network? I am trying to access my friend's broadband via her Wi-Fi router. When I used her password I received the message "connected with limited access." Then searching web I get "server not found" on all sites. There are several possible causes and usually a simple solution. Low signal strength is a common problem so make sure that your laptop is close to the router, preferably within a few metres, and try again, re-booting your PC and entering the password. Once the connection has been established you should be able to do so again when the PC is back in its normal location. If that doesn't work ask your friend to switch off the router and all PCs and devices that connect to it. This should clear and reset any settings that may be causing conflicts. Your PC should also be switched off at this time. She can then switch the router back on, wait for the lights to stop blinking and the Internet light to be permanently on. Her PC should be next, wait for it to reconnect, and then it is your turn. Once again make sure that your PC is close to the router, showing at or near maximum signal strength.
