Hi there

I have changed from WEP to WPA/PSK security on my wireless router. Since
   doing that I appear to get very frequent dropouts (from none
previously). Signal strength appears to be lower.

Wireless router is Belkin VOIP 802.11g Gateway

Laptop 1 are using one of two Netgear WG511 PCMCIA cards (version 1 and
version 2 of WG511) and have tried using windows management and netgear

Laptop 2 is using Acer SignalUp wireless networking with Windows management.

Any help appreciated?
