  1. Thanks for your article.. it works perfectly..

  2. The steps above did not work for me, although they worked for many others as seen on other websites.

    What worked for me is going to Network and Sharing Center, right clicking on Cisco AnyConnect Client, go to Properties. There, I unchecked the IPv6 connection, and on IPv4 I went to Properties and changed from static to dynamic IP.

    Good luck

  3. Thanks Alex, happy that you got it working.
