OS X V10.7 Lion :: Wifi Disabled After 10.7.4 Update
Jun 10, 2012
Wi-fi was working perfectly all they way till I ran the latest update 10.7.4. Â
Now when I do a cold shut down, the wi-fi on the top right hand corner is blank. Cannot do anything to turn it back on. I always try to turn on, but fail. Â
Basically, it comes down to restarting the computer and praying that the wi-fi signal comes back on. Sometimes, I have to do a cold restart and it seems I'm playing a gambling game. Maybe after 3-4 times the wi-fi signal will become normal again. Â
This has been happening for about a month. Yes, I'm just getting around to complaining. I did not do time machine, so I cannot go back before this happend. Either, I do a whole another system install or there is a patch I could get. Â

I have a late 2008 Aluminium Unibody MacBook (5,1) and installed 10.7.3 via software update without problems. But when I turned the machine on next morning, Wi-Fi was disabled and could not be activated via the menu bar control or network pref pane. After a couple of reboots--two, if I remember correctly--the MacBook booted up with Wi-Fi active and connected (I use a Fritz!Box 7390 WLAN router with both 2,4 and 5 GHz networks, connecting via 5 GHz by default).Â
I did then repair disk permissions and re-applied the Combo update. No cure, obviously. Same again this morning - no Wi-Fi on startup first, connection just after a couple of reboots. Wi-Fi hardware (Broadcom BCM43xx 1.0 , firmware 5.100.98.75.19) always shows up in the system profile, it's just that it's disabled first.Â

After I did the 10.7.4 update on my mid-2010 macbook pro core i7 this evening, my wifi adapter/internet is not working, it is grayed out and says "no wifi hardware found". I have re-booted my machine 4-5 times but that did not help.Apparently, if I boot into recovery partition via holding Cmd+R > there my wifi is working and is properly connected. Infact, I am writing this message through that receovery partition safari window connected to wifi just fine.Another weird nothing I noticed is if I boot into the Safari-only Guest User account, there also wifi is working just fine, no problem.However, in both of my user accounts, it is giving me this "no wifi hardware found" error and won't connect to internet. In fact, ethernet wasn't working as well in user accounts.

I just updated my (brand new) iMac to OS 10.7.4 and now I can't download the wi-fi update V1.0 which fixes the issue of not reconnecting to wi-fi network after computer wakes from sleep.

Before the 10.7.4 update the WIFI connection from the iMac 21.5" to the airport extreme router works fine!
Now it's failing several times a day! it looses the wifi connection and you are unable to see any wireless accesspoints or SSID's
Macbook pro, iphone & ipad + PC's still works fine!Â
The only way to get the wireless up and working again is to shutdown and restart the iMac.Â
In the log i can see alot, don't know if this is some clue or error occuring just after the wireless connection is dropped for unknown reasons.Â
"kernel: 2329.723808: ath_chan_set: unable to reset cannel XX (XX00Mhz) flags 0x10080 hal status 17"
"kernel: 2632.354892: ASSERT: Can not reenter VAP State Machine"
"kernel: AirPort: Link Down on en1. Reason 8 (Disassociated because station leaving)."Â
Turning off and on the wireless interface only shows the following in the log, and the wifi will not see any SSID's : "kernel: 71847.200440: switchVap from 1 to 1" Â

Problem: After recent update to Lion 10.7.4, my Wi-Fi signal via Internet Sharing keeps dropping. Have multiple iDevices failing that were working perfectly with 10.7.3 (Nook and iPhone 4). iPhone shows full Wi-Fi signal strength and works for a short time after reset (via Wi-Fi off/on, Internet Sharing off/on). Continues to show full Wi-Fi signal strength but loses connection after 1-2 minutes. And not just internet connection; I can't transfer pics/vids from iPhone to iMac either. Have switched to a channel no one nearby is using (channel 9) to no avail.

I think I need it to play Yahoo games. I went to Safari Preferences and checked Enable Java. (Enable JavaScript was already checked.) But when I click on a Yahoo game, the page loads, yet the game doesn’t appear. I thought I could just enable Java when I wanted to play, then disable it when I wasn't. Obviously this isn’t urgent, but if there’s an easy and safe way to play, I’d like to know.

I get a little annoyed when doing CMD+SPACE and seeing the list of lanaguages being switched between.So I did the normal thing I did on SNow Leopard/ Leopaard/ etc, and disabled the switch in Keyboard preferences.Even though they are both switched off, the langauges still come up when I choose cmd+space.

So as the title says when I boot up my iMac, on occasion, it seems to have the "Updating" Status bar, then the mac boots normally, then the sound is disabled. As I said though this dose not happed all the time but when it dose the only way to fix it is by rebooting the iMac once again.

I disabled local snapshots because they were using up 43GB of hard disk space that I needed for other things.I used this command in terminal: sudo tmutil disablelocal..Instead of having the local snapshots be deleted, they are somehow littering my hard drive still.I have searched my drive, but still can't find them. Is there any way I can reclaim this hard disk space?I also tried running a repair in disk utility and re-indexing Macintosh HD.

I just noticed that on my login screen, "Guest" appears even though it is disabled. I have not tried to run it, but when I do click on it I get the message that the computer will reboot into the "Guest" mode. I stopped at that point. This can't be normal.

I just did the firmware update from my late 2011 Macbook Pro 13" (running 10.7.3) which all seemed to go fine, except I can't connect to my wifi any more. There is another 13" macbook pro, a 13" macbook air and 2 android phones which can all still access the wifi. I keep getting a message that my password is invalid (I know it's not). Everything I have tried has been done with the power supply connected.I have:
-rebooted the wifi router
-rebooted the mac
-shut down, waited for 5 minutes and rebooted
-repaired permissions
-deleted the keychain and tried to make a newconnection
-tried reinstalling the EFI firmware update from a .dmg (it won't let me)

installing the 10.7.4 update on my 2011 iMac 27". The symption is that the iMac drop its Wifi connection after a period of time and when that happens the iMac cannot detect any wifi networks in my area (disabling & re-enabling Wifi on the iMac doesn't help). I have to resort to restarting the iMac to revive the wifi interface. Note that my other devices (including my iPhone and my MacBook Air)can connect to my Airport Extreme without any problems.

This morning I performed a 'Software Update' on my Macbook Pro and 6 new items were updated. The Mac then asked me to restart so I did but when it came back on I logged in as normal but it won't connect to my wifi unless I type in the password. I've tried Utilities > keychain manager but all I get is 'Access to this item is restricted' (when I click on show password and login again). My ipad and iphone are still okay and can access the wifi fine.

It took me a lOOONG time but I finally bit the bullet and bought a macbook. So far so good, I will be giving it a memory upgrade in a few weeks but right now I could use some serious help.
The computer won't connect to my Netgear WGR614 wifi router. I called Apple, they said the airport works and I may need a router firmware update. I updated the Netgear router. I have tried using the WEP, the WPA and also tried with the router set to zero security. The macbook still won't connect. Here is the kicker, my old windows based laptop and my wifes newer netbook picked up the new upgrade without issue.
The macbook (I loaded all the macbook updates with hardwire) will go through the network diagnostics and end up being unable solve the problem.

I updated with the latest Lion patch yesterday and since then Entourage has either hung or taken a very long time to update from our 2003 Exchange server (I have MS Office 2011 but as you're probably aware, there are issues integrating with a 2003 Exchange server). how this might be fixed, short of updating both our 2003 Windows Server to Windows Server 2008 x64 and Exchange to 2010 so I (the only Mac user out of 85 staff) can use Outlook 2011?

Started the 10.7.4 install, and it halted. Turned my Mac off, started it back up, and apparently the 10.7.4 update didn't install, but it has caused the Mail function to not work AT ALL - I get a long error report that is auto sent to Apple.Â
I downloaded Lion from the Apple store, but have my Snow Leopard disk. How do I go about re-installing Mail?Â
