Three weeks ago I installed KAV 6.0.3.837
Since that time I cannot connect to the internet automatically.
I have a wireless Cisco Linksys connection.
As soon as I disable Kaspersky I am able to connect after some time.
I do have to switch sometime between the Linksys wireless internet connection and the Windows XP wireless connection.

What do I have to do to get automatically internet acces when I startup the PC.

Please give me advise to solve this issue.

its seems a anti-hacker problem. did you try to set the level of this component to Training Mode ?
or change wireless zone to Internet.
look here for more details:
