How to Fix Error - After Cisco AnyConnect VPN Client connected access to Internet sites becomes unavailable.?

After Cisco AnyConnect VPN Client connected access to Internet sites becomes unavailable.

I have Asus laptop with Windows 7 64-bit Home Edition which
I want to use for work from home.
My company provided me
with special website from which I'm able to successfully
establish Cisco AnyConnect VPN connection.
But each after this VPN connection has been set, I loose Internet connection, so I cannot open any website on my Firefox, Internet Explorer, my Thunderbird e-mail box also becomes unavailable.
And the only way to get normal Internet connection back is to
reboot my laptop.
I asked for the help support guy who is responsible for VPN connection in my company.
He checked my  proxy configurations both manual and automatic, and some other
things from VPN side, but found nothing wrong.
So he thinks there is something inside Windows 7 which blocks network access, but he is not Windows 7 expert.
Please advise.
