Mac Airport Leopard Problems

So you updated your Mac OS Leopard to the new 10.5.1 and suddenly you are having problems with your WiFi connection. This happened to me, sometimes I am connected and sometimes not, restarting did not solve the problem. I had to do some online search to find out how to solve this problem. I thought I will share my findings:

I think there is a bug in the Airport driver but until Apple fixes it, there is what to do:

1. On your Router change the Wireless Mode to G-Only
2. On your Router change the Wireless Security Mode from WEP to WPA or any advanced security mode higher that WEP.
3. If you have multiple wireless profiles, delete them and keep only one.
   

This should get you going till the next Leopard update.

If this solution doesn't help, then you can try plugging in the power supply. For some reason, this improves the WiFi strength of the Macbook...

If you tried other solutions and they worked, please feel free to share them with us.
