Does this laptop have the capability of using wireless?
Click Start, and then click Control Panel. Click Performance and Maintenance, and then click System. On the Hardware tab, click Device Manager
Do you see anything with a yellow exclamation mark?
I am still here -- This is the first time that I have heard back from you in the last 25 minutes.
In the Device Manager, what is listed under Network adapters?
I think we have found the problem. The only network driver listed is not a wireless card which means that you will need to plug in your desktop computer directly into your router/modem in order for it to work properly.
Alternatively, you could buy a wireless USB adapter in order to use wireless on your desktop. They can be bought at Best Buy for around $30-$50 or almost any electronic store.
No problem! I am glad I could point you in the right direction so you can get the desktop working again.
