Vista - Losing Internet connection when resuming from sleep-mode

My machine never had this problem until around the time I installed SP1,
which I initially suspected was the problem. I also upgraded the firmware on
my Linksys wireless G router, which could also have been the culprit. But
after reading many threads someone mentioned they had an issue with McAfee,
which has caused other problems for me in the past. So I uninstalled McAfee
and reinstalled it again and voila, the problem went away. There are several
reasons that can cause you to loose connectivity after returning from sleep
but I would definitely recommend if you're running McAfee to uninstall and
reinstall it again to ensure that this is not the cause of the problem.

UPDATE - So after reinstalling McAfee and having no problem for the past few
days, the next time my computer came back from sleep after I posted the note
below, no internet - how ironic! However I noticed that Outlook downloaded
my new emails so there was a connection but I couldn't connect to any web
pages and Skype couldn't connect so I suspected it may be the firwall. I
disabled the McAfee firewell and voila, I could connect again. I then
re-enabled the firewall again and all was fine. So for some reason, every so
often McAfee firewall will block you when returning from sleep. At least
I've found a way to reconnect to the Internet without having to reboot the
computer all the time. As a side note, Windows never found a problem with
the network when I used the 'Diagnose and Repair' option, because there
wasn't a problem with the network, the problem was with the firewall.

So I called McAfee and they got me to do the following, I haven't yet tested
the changes long enough to know whether it will fix the problem but thought I
would post this info anyway. I'll make another post in a week to let
everyone know whether or not this worked.

Step 1: Click on windows start.
Step 2: Click on Run.
Step 3: Type %temp%.
Step 4: Click Ok.
Step 5: Delete all the files and folders. Please leave the files that
cannot be deleted; delete the rest.

Step 1: Click on windows start.
Step 2: Click on Run.
Step 3: Type prefetch.
Step 4: Click Ok.
Step 5: Delete all the files and folders.

Step 1: Open your Internet Explorer.
Step 2: Click on 'Tools' and select 'Internet Options'.
Step 3: Click on 'Delete cookies' and then click 'Ok'.
Step 4: Click on Delete Files.

Now click on "advanced" tab on the top and click "reset" on the bottom, this
will reset IE.
