Dlink Wireless and VPN

[simleep]

I have a Dlink DI 624+ wireless router connected to DSL.When I wire my portable to the router and run VPN (Cisco V 4.0.1) provided by my company , I have no problem. Once I switch to a wirless adapter (DWL 650+) and try and connect, no joy. All I get is IPSEC initialising until it times out. I can however surf the internet with IE with no problem, so there is a connection with the router. I have been looking everywhere for some solution, but nothing posted seems to work. Is there some brain out there who can help me crack this problem?

We run the cisco software for VPN here. Being in our IT department we won't allow users to connect in via VPN while on wireless for security reasons. Try disabling WPA and WEP when going through the cisco connection. Disabling the service "wireless zero configuration" may also help you get that one fixed up.
