Updated to 10.7.3. Wifi drops constantly.

Updated this morning. Then it would not hold a wifi connection for more than 5 seconds at a time. Had to use Lion Recovery to install a Time Machine backup to 10.7.2. That took over two hours. After that wifi was semi-ok. Lion has always had a problem with wifi. I am very disappointed with how Apple has handled the Lion rollout. So many problems. I would suggest anyone having problems with wifi think twice before installing this update.

iMac, Mac OS X (10.7.2)

Well, we will need more information in order to try and help you. If you feel so inclined, I would do/answer the following:


1. What is the make of your Mac (year, etc. Use System Info report to see this).

2. What kind of Wireless Router are you using?

3. Have you tried using the combo updater? You can get it here: http://support.apple.com/kb/DL1484


If you download and update via the combo updater and you still have connection issues, can you verify the driver info by running a system info report and post the WiFi section info into this thread? Here is what mine looks like on my iMac running 10.7.3:

Mine is an IMAC 21.5 inch, mid 2011. I'm in Berlin Germany running a Speedport 723 router. I have not tried running the combo updater. What is the difference between that one and the normal update? I can try running that tormorrow morning my time and if it doesn't work I can always go back to the 10.7.2 using the time machine backup.
