I recently purchased a Lenovo T510 which has an Intel WIFI Link 1000 BGN card under Windows 7 (x64). Everything works fine with it until I try to use the VPN software over a wireless connection (everything is fine hardwired). A VPN connection is made to my server and all the logs look good except no traffic will pass to or from and I cannot ping the servers.
I have tried using different Intel Centrino drivers from most current to a set that was dated around march of '09. I've heard of people having similiar problems but they were mostly based on Windows Vista and a different card so i wasn't able to follow the "fix" to the letter. The problem in those machines was something to do with the Cisco install disabling the DNE on the adapter. I didn't have that particular problem.
I asked my server provider if I could use software other than Cisco just to see if it is an exact driver incompatibility between INTEL and CISCO but they informed me that I had no chice there, I could only use the Cisco VPN.
Any help would be teriffic and greatly appreciated. I am going to open a thread at Intel and Lenovo and link them back here.
Thanks again for any assistance
VPN version: 5.0.07.0290
Intel Centrino Driver: damn near every one of em since 3-09 to current.
It is indeed a Linksys wireless router. Why do you ask?
I should point out that I have another new Windows 7 (x64) laptop in the house which works fine in all modes of transfer with the Cisco VPN software. Of course that computer has a Dell Wireless 1520-N NIC instead of the Intel WIFI link 1000 (which I suspect to be the problem)
