Lion:WiFi not autoconnecting after sleep mode

Upgraded to Lion yesterday, now when Mac is recovered from sleep mode the WiFi preferred network is not automatically connected. Never was an issue with Snow Leopard. I added my connection as a preferred connection in the Networks/Advanced page but it stil doesn't reliably work. I must select the network from the list and connect.

Yes, ALMOST the same issue here! I am running a WIRED connection from my desktop to the AE. I run 10.7 on a MacPro 1,1 (2.0GHz), although that shouldn't mean anything.


The strange thing is that when I run the Network Assistant/Diagnostic, I get ALL green lights. However, my Airport Extreme (Dual-Band) does not display in my Airport Utility list -- something obviously is not computing, as that does not make any logical sense whatsoever. Those behaviors should be mutually exclusive.


I hope I'm not threadjacking, but this is the only post I found that approximates my issue. I will start a new thread if this is too far off-base.

i've been having this problem for over a week n it drove me crazy, but i found the solution! Click on the wifi signal sign, then on "open network preferences", once u're in the network preferences, click on the drop down list in "location", and then on "edit locations" .. and simply delete the old location u were using, it might be "automatic" and just create a new one .. that'll reset ur wifi preferences and it should work like new from there on 🙂

Late 2010 Macbook. Same problem since upgrading to Lion. After reopening the lid, it will scan for a network and then claim no conections available. This has been true at work, home, parents home, friends home-- all preferred networks where I frequently connect. I changed the location as some had suggested, from automatic to creating a location profile. The problem repeats itself to the point of irritation. To no avail. I intend to call Apple Care and will post my results here. Yuck! What a loss of productivity!

Macbook Pro Unibody. After upgrading to Lion, my problem concerning WIFI was that I had no more autoconnection to my home netwoork.


To fix the problem was simply to delete the plist file corresponding to aiport i.e


/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist


1/ disable airport

2/ delete the plist file

3/ enable airport and select your favorite network again


nb: I had several other problems with Lion they allhad been fixed deleting the related plist files...
