Unable to Resolve Hostnames after Quitting out of Cisco AnyConnect

Dell Laptop, running Windows 7 SP 1

Cisco AnyConnect 3.1.02026

AT&T DSL with 2Wire Modem, directly connected

Hi,

My problem is not with Cisco AnyConnect.  Rather, it's when I quit out  of the AnyConnect Client, I can no longer resolve any hostnames, and I either  have to reboot Windows or power cycle my modem, or both.  This does not  happen every time, but quite frequently (perhaps, once out of five  times).  Has anyone else experienced this problem?

Viewing the events put out by acvpnagent during the time of the incident, I see the following (for what they're worth):
