Vista - Local Network Fix

I posted a couple of days ago about my network access dropping from local & internet, to local, to no connection, after recently upgrading to vista.
I tried every solution othe people have posted on the net but my problem still persisted.
So last night I reinstalled vista and created a restore point after the 1st start-up. I was able to use the internet without interruption for over 5 hrs. Then this morning windows installed updates. After the updates were installed my problem started again. I went ahead and restored my computer to the 1st restore point, and now it is working fine.
My fix to this problem is to not install any updates. I know that it is not the proper fix, but for anyone as frustrated with vista as i am, this is a way to maintain your internet connection.
I am a newcomer to vista, but I found out that this problem has been happening to other for years. I can't understand why microsoft wont fix this problem.
If this post helps anyone else with the same problem, please reply with your story.

the problem with not updating vista is it leaves your operating system wide open to attack , thats exactly how conficker spread. An unpatched OS can make your firwall and AV next to useless

why dont you set your updates so they are not automatic , then pick the updates to install , install them one at a time run your pc for a while each time until you find the offending update
