Internet Connection Sharing WON'T WORK!!!

[smurof7neves]

It's "connected" on the base computer, my desktop. However, my laptop has that annoying spinning circle thingy for a bit, then shows the bars with the exclamation point.

I have absolutely NO internet access because of this. I don't understand...it worked before in this same setup! Same password, same ad-hoc/computer-to-computer network, same PCI wireless card and antenna.

Step 1. Close all applications that use the network — browsers, e-mail, chat, video, weather, and any other app
that might be automatically updated in the background.
Step 2. Click Start, type device manager in the Search box, then press Enter.
Step 3. Browse to the list of devices and click to expand the Network adapters section.
Step 4. Right-click on the first adapter under Network adapters and click Uninstall. Windows will ask whether you
want to remove the associated device drivers; say no, you want to keep the device driver. Repeat for all network
adapters on your system under Network adapters.
Step 5. Close Device Manager.
Step 6. Reboot.
When you reboot, Windows will think it’s found new networking hardware and will set up fresh connections. By
the end of the reboot, your Network should be back and running in streamlined, trouble-free form.
