I have a strange problem and need help. I have a Linksys wireless
access point (BEFW11S4) connected to a cable modem and in my laptop I
have an older Linksys PCMCIA WPC11 ver 3.0 wireless-b card. Connects
fine and access to internet is smooth. I have no problem connecting to
company network via cisco VPN 4.0.3.

The problem comes in when I try to use my new linksys wireless card
(Wireless-G pcmcia card). Everything works great EXCEPT the VPN won't
connect. I can't get it to work to save my life. I can walk over and
plug a hardwired connection between the laptop and the router and VPN
works fine.

As a test I grabbed a new Linksys Wireless-G (WRT54G) access point to
see if that helped. Using the Wireless-G notebook adapter I have no
problem with all internet access EXCEPT the VPN via wireless won't
connect. I can walk over and plug a hardwired connection between the
laptop and the router and VPN works fine.

What is wrong with the wireless such that it would work fine in all
aspects except allow the VPN? No difference in the configs except I'm
trying to use the newer Wireless-G notebook card.

thanks,
russ

Maybe you have some kinda IP reservation for the WPC11 or port
forwarding enabled?

Have you checked that the 'Deterministic Network Enhancer' service is bound
to your wireless network settings. It is within the properties of the
connection in the same place as the TCP/IP settings would be found.

This service adjusts the MTU of the VPN packets or else they would be too
big and would get dropped.

It is possible that this service was not automatically selected when the new
card was installed.

Regards,

Martin
