Trouble accessing Internet

[cjanien]

I have a Dell desktop with wifi. It can see the AP (very strong signal), but it cannot access the internet ("limited conductivity"). I tried cycling power on the modem and AP which helped temporarily. Reboot does nothing. There are 3 other notebooks that have full access to the internet thru wifi to the same AP and cable modem.

The Dell has Vista op sys, and I've run thru all the diagnostics with no real solution. This pc normally uses a wired connection with no problem.

What should I look at to get this going?

Thx

So you must be using a USB Wireless adapter? Have you installed the software for it?

Yes, I have a D-Link DWA-131 Wireless Nano N USB Adaptor. Connection Wizard and Connection Manager are both loaded on the desktop.
