I have successfully used the Cisco VPN Client V 4.0.2 (D) via my laptop's wired nic through a LinkSys WRT54G for over a year. I recently purchased an Intel PRO/Wireless 2200GB mini-PCI card for the same laptop. I can access the internet, but when I try to start the VPN client, it hangs on "Initializing the IPSec link..." and finally gives me an error window that reads: "The necessary VPN sub-system is not available. You can not connect to the remote VPN server."
I have not had any luck getting help from LinkSys, HP/Compaq (my laptop and wireless adapter vendor), or my company's network support (they say they can't support every combination of personal router and wireless adapter).
So my questions are these: Should this work? Are there additional router settings for wireless VPN support that aren't needed for wired support? Should I punt and get a different wireless adapter...or a different wireless router?
