10.7.3 no wifi connection after wakeup

Since 10.7.3 update, I have to manually reconnect to my WiFi network at every Wakeup from sleep.

It WILL try to connect by itself, but it will quit trying after 6-8 seconds.

The WiFi icon in the menu bar will then remain gray until I click on it and manually choose my WiFi network.

It DOES reconnect automatically upon Restart, though.

My WiFi network comes from a third generation Time Capsule, with the most recent updates applied.

Had no such problem yesterday in 10.7.2.

iMac, Mac OS X (10.7.2), Mac OS X Lion 10.7.3

I had the same problems after updated the lion 10.7.3 update early in February. Then I went back to 10.7.2 and all was fine.

Now that there is a WiFi-fix for 10.7.3 out, are the problems still there?

Same here. Would be nice to see any workaround for this.

I installed the update a few days ago and it worked...BUT only after doing the following:

1. open network preferences

2. hit the advanced button

3. under preferred networks

a. eliminate invalid networks (I had a few....like Apple Store)

b. select: remember network this computer has joined

c. save changes

I've been trying to find the solution to this for many hours and I found something that works for me on my 2009 21.5" iMac. We have a 2008 Macbook in the house also which is not having issues so I decided to check the settings against each other. In the network preference I unchecked the Ask to join new networks field. Viola! Working for me now with no issues.

This is spot on. I tried it and it worked! Thank you so much.

I solved changing MTU in preferences->network->wifi->advanced->hardware from automatic value 1500 to manual 1453.

bye
