RE: Cisco VPN 4.8.01.410 and Vista RC1 Power Management

Dan,
Thank you so much for posting this. I was having this problem and it was
driving me crazy! Any time Vista came back from sleep or hibernate, the
wireless connection would be totally unrecoverable, IE7 would no longer
start, the control panel would open but be empty and network settings were
mostly unavailable. I found that the LAN connection would still work if
connected with a Cat V cable.

In addition, shut down would also freeze intermittently requiring the
awkward Windows did not shut down properly restart - Starting normally always
worked.

I didn't even guess that the Cisco VPN client (4.8.01.0410) was the problem.
I was thinking it was the wireless driver - though I have the most current
driver. I am so lucky that I found your post. Uninstalling the Cisco VPN
client did fix the problem. Reinstalling it confirms the problem.

I found the following solution: I removed Cisco VPN client 4.8.01.0410 and
installed Cisco VPN client 4.8.01.0590. So far, no problems.

If anyone needs help finding the VPN client I am using, reply to this post.

Here are a few key words that may help others who search the newsgroups to
find this solution: Cisco VPN client, Vista freeze, shut down, sleep,
hibernate, wireless fails, control panel freezes, NIC
