If it is a HH 2.0 the problem could be one of these:
1) If your PC has an 802.11n WiFi Adapter then, as has be saids already, refresh the drivers for it.
2) Alternatively download a free program called inSSIDer. Use this to find out what WiFi Channels are in use locally and then set the HH to use one that isn't in use and is at least two channels away from any that are.
3) If the failure is occurring when you enter the encryption key, (again assuming HH 2.) ensure that PC's WiFi adapter supports WPA.
