If you delete the network from the Preferred Network List and then rejoin the network after a reboot, does the issue go away ?

Unfortunately, 2nd day gave me the same loss of wifi on start up. Is there a way to restore the previous system before the update?

after speaking with Apple and going through a number of resets for about an hour. Tis was my resolve
I have an an early airbook.
and I am now up and running after an hour with Apple support.
If you just recently downloaded you still have 90 days support
for the OS and they will work with you on it.

The below has solved my Safari hanging when loading web pages and eliminated my finding the wifi on boot up. It has been a month now and waiting a minute always works for connecting to my airport extreme on boot. I was cleaning behind my desk and realized that the ethernet cable was still attached to the back of the iMac even though I had moved the airport upstairs. I disconnected it. I also opened network preferences. The wifi was moved a long time ago to the top for priority, but the inactive ethernet and firewire were still listed. I removed both the ethernet and firewire so the only connection listed is wifi. My computer has now reliabily found the internet for the last 3 weeks without waiting. It appears that having the other two options disrupts the connection process on boot. It also must cause the computer to continue trying to use the connection when using Safari.
