I've got a Dell laptop, and have a problem connecting to wireless networks. For example, my brother lives on his own, and has a wireless internet service. Sometimes when I visit him at his house I will take my laptop with me to take advantage of his wireless service. Anyway, when I try to connect to his LAN, it will say I am connected and it will also say "signal strength: excellent"--yet I am unable to visit web sites, log onto AIM, etc. What could be the problem? Thanks
If it says you're 'connected' and signal strength is 'excellent' then you are connecting to his wireless router at least.
Next thing you should do is open command prompt and see if the router is assigning your notebook an IP address from the router and grab all the ip information?
ipconfig /all <---will display all ip info.
I don't think theres any authentication/encryption/security in place on the router. If their was it would have prompted your for the network key before
it states connected and signal strength as excellent.
Do you have a firewall running on your notebook?
