"Laptop Does Not Connect to the Internet."
No Wireless Network in Range
The problem may be that the laptop is not in the range of a wireless network. Check to see if another laptop nearby is within range and can connect to the internet. If another laptop cannot connect to the internet, you may need to move closer to a wireless network.
If another laptop nearby can connect to the internet, the problem may be that your laptop's antenna is broken and must be replaced.
Broken Wireless Card
If replacing the antenna does not fix the problem, the wireless card may be broken and must be replaced.
