Slow connection when using Cisco VPN on a broadcom card

Hi Guys,

Another interesting one for you guys.....

When I/We use CISCOVPN to connect to some of our clients, the VPN connection is very slow
When using a Broadcom card

However if I connect to the same client using a machine with a different make of network card - all is ok!

I have tried changing MTU rates etc but to avail
I have the latest Broadcom driver and chipset + bios

Multiple units affected - but only with the Broadcom cards

If I use another type of VPN - Firebox to connect to the same client using the Broadcom card - all is ok

Is there a patch or an updated CiscoVPN client that resolves this issue?
CiscoVPN software version is 5.0.00.0340

This is a workaround until a fix is issued but seems to work. In the device properties of the Broadcom NIC, disable "VLAN Priority Support"

(in XP for example: Right-click My Computer > select Properties option > click Hardware tab > select Device Manager button > expand Network Adapters entry > right-click Broadcom xxxx Wireless NIC > select Properties option > click Advanced tab and find the VLAN Priority Support option and disable it)

I had a really strange problem somewhat similar to this once and it turned out to be a problem with the NIC driver.  At the time I was using the latest version of the NIC driver, but a few months later a new driver was released that completely fixed the problem.

This is a known issue. Cisco VPN clients are poor design. Use NCP http://www.ncp-e.com. Much more professional, faster and more reliable.

Cisco VPN client is fine, the issue is the broadcom card.  I have had more problems with broadcom network cards than any other.  And it is always weird problems like this one.

Whatever you say. The NCP client has zero problem with this hardware. And the Cisco client is full of flaws and very unstable as most people know.
