MBP GKB  5.4.1/7.4.1 Airport update

I've been using the Time Capsule as my primary network. I extended my network with an Airport extreme (version prior to the latest). It's been working on 5.3.2 and has been solid as a rock. When the update came out, I was excited. I downloaded it and installed it and WOW my internet connection was screaming fast! It lasted just long enough for the back up to start on the Time capsule. The TC started failing backups, my connection to the net turned into the slowest thing since my 56k modem days. I started out by believing that Apple could do no wrong and fussed at my ISP. Well, I started hunting around and it seems others are having issues with this update. I'm noticing connection drops, the email client won't log in, I'm actually trying to connect to my neighbors ISP just to download the older version (it's still on your mac in the library directory, so if you can't find it or can't connect, look there) I back loaded to the 5.3.2/7.3.2 version and what do you know, it works great again. Solid as a rock. A week went by and It was working well. I thought again it might have been the ISP and updated it again (because my Airports were screaming at me 'Update available!') It was super fast for about 3 minutes. I was excited again for 3 minutes .. then it was back in the commode again. I'm now back on 5.3.2/7.3.2 and am happy to stay there until apple fixes this patch. Three words for you my friends ... DON'T DO IT!!!!'
