Wireless USB adapter getting

We have a Linksys wireless-N Broadband router (model WRT160N) and Wireless-N USB Network Adapters with Dual-Band (model WUSB600N). We used them before with a satellite connection and have recently switched to using a high speed internet connection with a fiber optic line. We have two desktops, a laptop and ipod touches that were all working with the router. One of our desktops can no longer connect. I have tried many things but can't get it to work again. I have unplugged and replugged in the router. I have reconnected the adapter. It says it is successful in connecting but then it doesn't work.

One thing that continues to come up when I have the adapter plugged in is this pop up message.
"The software that you are installing for this hardware PCTools Driver(no idea what this is) has not passed Windows Logo testing to verify its compatabliity with Windows XP" It gives a choice to "continue anyway" or "stop installation" I push continue anyway but the message pops up again every few minutes.

When I open the Linksys window, it says that it is connected to the wireless network but doesn't show any signal strength or link quality. On the connect section, it shows the network and that it has a strong signal.

When I open the Network Connections window under General it says "acquiring network address". It continues to say this the whole time I have the adapter in. Under Support it says "Invalid IP Address" and lists the IP address as

I have switched adapters with the other computer. Both work in that computer and neither work in the computer in question.

I would get rid of PCTools altogether. Uninstall it and that will almost def. resolve you NIC issues provided you have the proper and most current drivers installed for those NICs.

3 Questions come to mind:
1) Are you using the same Operating System for ALL PC's in your network?
2) Have you attempted to re-install the most updated drivers for your Wireless NIC's?
3) Have you attempted to disable PCTools? And or if you absolutely need it, have you imported the proper rule list? This will sometimes wreak havoc on your network since you already have a firewall in your router... Let us know.

All PCs are XP. I have reinstalled the drivers on the NIC. I have no Idea what PC Tools is or if I need it, could you tell what it is?

Also in device manager I have yellow ! next to two PC Tools Drivers, should I disable?
