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.
Info:
iMac (21.5-inch Mid 2011), Mac OS X (10.7.4)
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

After Update 10.7.4 i have problem with WIFI. It´s always off to start it on i must reboot my computer. Why?

iMac (27-inch Mid 2011), Mac OS X (10.7.4)
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
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.

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.

Whether through the App Store or the Apple download page, it starts to download, gets a certain way through, and then just stops. In the App Store, after awhile I get a message that Software Update can't connect to the update server. On the Apple.com download page, it just stops downloading. I don't think it's our internet connection, because the update worked just fine for our other iMac (which is older than the one I'm having trouble with).

I checked on the printer and scanner page that Lion supports my old Epson Perfection 2450 scanner. [URL]. Lion cannot seem to recognize my scanner, I have tried everything. Is there a way to redownload the driver but not through Software Update? There seems to be no update for Epson driver after installing Lion.
View 7 Replies View RelatedThe recent software update has caused a problem. The update for Air Port Utility was corrupted and did not download. I have run software update several times since then and nothing has changed. How do I clear out the corrupted file so update can start over? (MBP Lion 10.7.4)

When I try to download Lion, the download sign in window appears and is populated with someone else's Apple ID. If I change the ID to mine and use my password I get 2 messages:Â "We could not complete your request. There was an error in the App Store. Please try again later. (4)" Click OK and 2nd message: "Unknown Error"Â Â iTunes does not exhibit this, and normal sign in to App Store shows correct ID, only the Download Authentication does this. I have been able to update other Apps just fine, this requires a purchase, and is the only difference.

for the last few days my wi fi cuts out. If I go to the diagnostics it turns back on. It says that my network configurations have changed but then allows me to access it. But the next time I go to use it it has gone again.
View 9 Replies View RelatedI have an iMac running Lion hardwired to an internet connection and want to create a wifi network from this connection I have gone to 'create network' and set up - all seems fine. I have then tried to connect to this network with my iPhone. The phone recognises the network and it looks as though it has connected as it is ticked in the networks, but unfortunately it hasn't as my phone won't connect to the internet.Â

My brand new iMac will not stay connected to wifi. When I try to open Safari it says a wifi connection does not exist. When I diagnose the problem it connects to my wifi before I even get a chance to choose a wifie network to diagnose. This happens every single time.

I'm currently running on Mac OSX 10.7.4. Access to my NAS via wifi is very slow as compared to accessing it via Windows. I've tested with both AFP and CIFS but both are equally problematic.

When downloading small files online they will download through Speed Download. Before I installed Speed Download it would just download through the regular downloading client. How do I change it back to using the regular one as standard? I use firefox btw
View 6 Replies View RelatedSince installing Lion I lose my wireless internet connection frequently - only from the IMAC, not from the IPAD or Dell. I called support and after quite a lengthy "try this" session, I was told that this was a known problem. I can always get it back but sometimes have to unplug the router.

i want to get an imac and put it in my room but there is no place to plug in my modem and router up there so i was wondering if there was a way to wirelessly setup my imac with the internet.

My brand new imac randomly disconnects from the internet. We have a BT hub - wifi. I have googled this issue and see that it is relatively common and it is incredibly frustrating. It is fairly simple to reconnect each time but it is driving me mad having to. It generally happens when the computer is asleep but sometimes in the middle of doing something.

My music library is on my iMac, located in a different room of the house than my home theater system with a decent Denon receiver and good Infinity towers. I have an iPod connector to the Denon which I can use, but the iPod has a limited library of songs, so I would like to somehow access my iMac music library and be able to play it through the home theater system. Hard wiring the components is out of the question due to length of run through several rooms of the house, no basement and cathedral ceilings. I already have my iMac and my Panasonic Blu-Ray player both connected to my wi-fi, and it seems there should be a way to connect both of them using the wi-fi. The blu-ray player is DLNA, but the Mac isn't, so that is out of the question. Is there any other way to get these components to talk to each other over wi-fi?

This problem never happens with my MBP - and it is running a CCC Clone of the same 10.7.x system. But whenever I restart my iMac 20.5" it never automatically connects at startup. I always have to touch the wifi symbol in the menu. After that I don't need to select my home network - it will then find it and connect. But until I do that it doesn't connect. This has happened ever since I've gotten this iMac. Also annoying is that the sound output upon startup always defaults to my Logitech headset regardless of how I left it set in Sound settings.Â
