Alright... this is semi-serious, though feel free to point and laugh at me and mock me for my stupidity.

I baught a new ATX case for my PC this weekend. I removed each component and placed it on a polystyrene sheet and reinstalled them into the new case.

After I was done, I switched on the PC and everything worked... except my Wireless Network card. I checked the router and/or connection with the Laptop (built-in wireless) and the connection appeared perfect. After connecting, I could ping 10.0.0.2 and get a response.

When I switch on my PC, Windows notifies me of a "Wireless Network Detected". Indeed, it is the network that I want to connect to. As soon as I click on "connect" and enter the PSK, it says connected, though if I ping 10.0.0.2, it times out. I can't browse the network, internet or even ping anything.

Does ANYONE have a clue of what is wrong here??? I've tried the following, all of which failed:
  • Inserting the Wireless card into another PCI slot
  • Reinstalling drivers
  • Setting a static IP
  • Setting a dynamic IP (DHCP)
  • Reformatting and reinstalling Windows (d'oh)
  • Disabling the LAN adapter
  • Uninstalling the LAN adapter
  • Checked the Firewall settings on my PC (though I'm not sure how to add a new network zone in COMODO)
  • Disabling the Windows Firewall, as well as COMODO firewall

I hope that the wireless card isn't damaged, though it wouldn't make much sense as I can still search and find the network. If I set up a wireless network on my laptop, I find it with the PC, though the same problem: It connects, but I can't do anything. I can't ping it, I can't see any shares, and the laptop can't find the PC on the network.
