I have already installed the wi-fi software on my laptop but the problem is
that I cannot connect to the Internet or the Internet explorer cannot
open the webpage of the particular website. What's wrong please reply
its urgent
did you use ping? try it with ip (for example ping 213.180.130.200) not
with domain (ping www.onet.pl). when you have reply with ip option and
don't have reply with domain that means that you have problem with dns.
Make sure Internet Connection sharing is enabled on the server so the
client laptop to use it for internet access. search for connection sharing
here and you'll find more answers. Your signal is fine and finding the
network, but it is probably not allowed to connect or share the internet
connection on the main computer / server.
