Cisco VPN not connecting on wifi but works on 3G

[melvinp]

Hi
I am using the in built Cisco IPSec VPN on my macbook pro running yosemite OS.

Since last week, the vpn stopped connecting. My other VPN Forticlient connects and then immediately disconnects. This happens over Wifi.

However if I connect using the 3G of my iphone then both VPN's work perfectly fine. What's worse is that the same VPN's work fine on my other windows 7 laptop both over wifi and 3G.

So I am not sure what could be the problem here. Can someone provide tips on how this can be resolved?

thank you
Melvin

Create a second admin account and test the Cisco and Forticlient VPNs under the test admin account.
If the problem follows the user it's a system problem, if not it's a user problem.

Deleting and re-adding the WIFI interface is usually the first thing I do to test although it is a pain if you have many remembered networks as they will be wiped out.
