Internet will not connect on PC

Question

I have both a laptop running Vista and a desktop running XP and they used to both work just fine.

I configure something with the firewall, ip setting, or whatever I do and it works on the PC but everytime I restart the computer, it comes back as not able to connect. Sometimes it says limited to no connectivity.

I get a perfect signal on my laptop. This is a wireless router but my PC is not being connected wirelessly. It is plugged in to the computer.

I have done the router and modem turn off and wait thing, and to no avail.

Sounds like something keeps getting reset every time I restart the computer!

All firewalls are off...

Any ideas?

Answer 1

right click on wireless network connection icon on system tray (near clock) and click open network connections.. right click on wireless go to properties, at the bottom, remove the check on "Notify me if this connection has limited or no connectivity"

Answer 2

some anti virus programs prevent some connections, as they have a built in firewall,,,   programs like zone alarm,  can cause the same type of errors, if they are not configured correctly,
