I purchased a IMAC on Feb 1 and have had problems with it being able to connect to wireless after waking up from sleep. I had downloaded 10.7.3 and have since talked to Apple Care. I was elevated to another technical rep who spent a couple hours on the phone with me. He had me download something to my computer and he then sent it to Apple Engineers. He told me it would be a couple days before they got back to me.

He called the other day and tried two more things which didn't work. About every 2 out of 3 times my iMac won't reconnect after waking from sleep and I have to reconnect it manually. It's not hard to do that, but I certainly shouldn't have to. I was told by the rep. that Apple is aware of the problem for some people and that it is a software issue not a hardware issue. He told me I would have to unfortunately wait for a future update to hopefully fix the problem.

I have until Tuesday to return the IMAC. I am very seriously considering doing that because it seems many people have issues with this also. I originally had switched form an IMAC to a PC because my previous IMAC would drop it's connection in Snow Leopard. I was aware I was taking a chance in coming back to a Mac, but I really missed the usability, especially since I have an IPhone and will be getting a iPad 3. I also recently have purchased a Macbook Air 13 inch with 256 sad and really like that. It does take it a few seconds to reconnect after waking from sleep, but finds the connection every time.

I'm just curious if there is anyone who doesn't have this problem on IMAC's as I am considering returning this one and purchasing a new IMAC and seeing if I avoid the problem with a different one since the rep. told me it's not all of them just some. I don't want to try another one if this seems to be a really widespread problem though. Thanks
 
When people post on Apple related message boards, they usually do so, to report a problem and get help with it, thus one can get the impression, that almost every Mac has a problem.
But what do the people without problems do? Do they come to message boards and report on their working machines? They probably don't. Why should they?

Anyway, what I want to say with this, you will always see much more problem related reports than everything else. It's just like the news, they don't report, when an aircraft has successfully landed or a war hasn't broken out or the trains were on time or the workers we working. They only report problems.
Therefore you can't measure an existing problem objectively by the number of problem reports, as you don't have access to the other side, the side without problems.

Also know, that this site has a bit less than 700,000 members, that there are approximately 80 million Macs out there (probably more), and that of those 700,000 members 33 % have never posted once, which leaves 462,000 members. That is almost 0.6 % of all the Macs out there, lets round it up to 1 % of Mac users, which is an okay average. (not really a mathematically correct statistic, just an approximation)

Nonetheless, Apple computers, like many other electronic devices, are mass produced in high numbers. Statistics show, that there is no chance of a 100 % perfect manufacturing run anywhere. There will always be problems.

Try returning your Mac and get a replacement, maybe even test it in the store, if possible, to save you the trouble of maybe returning another problematic machine.

Unfortunately, the WiFi issue is "real" — as in — it affects virtually every 27" 2011 iMac. The same WiFi card works perfectly with Snow Leopard but drops connection in Lion. The problem is the buggy Lion driver (numerous reports show that downgrading the drivers will fix the issue). The reason why many people do not have any issues is because the connection problems only occur in combination with particular routers/configurations etc. If you are using an Apple WiFi router, you should be fine. But if you (like me) are using the WRT54G, than the chance that you will encounter the problem is very high. Unfortunately, Apple would not acknowledge the problem. I hoped that 10.7.3. would fix it but the connection still dropped after few hours (it lasted longer then usual though ^^).
 
Hi, have had the same issue on a IMac bought last week, spoke to apple care also but that didn't help. I tracked the problem down to latest software up date as before I updated all was fine. I restored from time machine an have had no problems.
I have s few days left also to return & only reason I will will be if I hear about refresh. All in all it's a great machine considering apple use to use old chips not so long ago(C2D) but the quad is just excellent when doing intensive video work. Hope this helps. If you can restore to before the update, you will see you won't have this issue.
 
My 27" late 2011 i7 also has a wireless problem with dropping out and not always connecting on wakeup.
My router is a BT home hub 3 and I have decided to switch to channel 10 instead of auto, this has helped a bit.
I have done updates but I will leave them because it isn't bothering me to much at the moment.
 
I'm having the same problem with my 5 month old 27". I didn't have the problem at first, but it seemed to start happining after about a month.
 
yup... same here with the problem of "no wireless on wakeup".... This problem did not start until I updated to 10.7.3... Im furious.. For those of you having the problem, try waking the computer with the power button.. this re-connects the wirless just like it should when you hit the mouse to wake.. AppleCare has been nice, but no help in fixing the issue.. Apple engineers have to figure out why waking with the power button works, yet with the mouse or keyboard does not!!!!!!!! This is ridiculous.. I just bought this $1800 iMac to get away from these types of problems that I had with my Windows machine:( HEEEEEEEEEEEEEEELLLLLLLLLLPPPPPPPPP APPLE!!!! HELP US ALL!!!
 
I just bought a 27" i7 3.4 about a month ago, pairing that with an Airport Extreme, and so far, I haven't had any wireless issues. What I am having issues with is kernel panics every other day now, which never happened in 10.7.2. Now that I have 10.7.3, I receive this every other day:

What's frustrating is that this didn't happen in 10.7.2.
 
I had this problem until I bought a new router now all Macs work correctly on my network.
 
Does the Apple Wireless router support "N" type speeds? What would the difference be between and Apple router and my Linksys?I would be able house a pc on the wireless router, I assume? Apple care did have me look at my wireless settings and they said they were good. I currently use a Linksys High speed router which works good with my Lenovo ultra book and so far with the Macbook Air, but it's only a couple days old.

I know Apple had me redo the update on my IMAC because the first 10.7.3 was "flawed" in some way. Before I did the update, the computer would find it's connection after sleep. I don't have away to use time machine since I haven't backed it up yet, haven't purchased an external drive. The update to 10.7.3 went fine with my Air, but it was the updated 10.7.3.

I guess I will take my IMAC back today and maybe hold off for now on getting one. I really like this IMAC size and the screen is great.
 
I purchased my 21.5" iMac in November 2011. It worked flawlessly at first, however after about one month, I started witnessing these WIFI drops. To be honest, I'd be happy if mine only disconnected after sleep and you'd have to manually connect it. You see, mine drops the connection everyday, whatever I'm doing. Sometimes during evenings I even drop the connection every 5-7 minutes, which is awful. I've tried updating to 10.7.3 (combo) which was a pain in the ass as I had to restart the download every time the wifi dropped out. I've also tried resetting the wireless-settings (worked for an hour or two). I honestly expect Apple to address this issue immediately.

In the meantime, is there something else one can do to limit the amount of dropouts?

I have had no problems since I downloaded Lion in the summer :)

What router do you have? A Trendnet router that I have had a bug which caused compatibility problems with my iMac.

Otherwise it's OK... macs have several quirks ... just like Windows.
 
I bought an airport extreme a couple of months ago hoping to resolve the "no wireless on wake up" issue. I still have the have the same problem.

+1

Purchasing an airport extreme did not resolve my issues either. My iMac picks up the wireless pretty quickly so it's not that big a deal. I think there is something wrong if this many computers all do the same thing.

Once I get things arranged, I may use a cable which was always my plan. It is inconvenient. Apple should fix this issue.
 
No Wireless problems whatsoever on mid 2011 iMac using a DrayTek modem / router.
 
I'm having the same problem as well. I have to manually connect it every time and more than half the time it still does not connect and I have to restart the computer. Not a big deal but it just gets annoying
 
interesting, I have this problem with my MBA. I never bothered to contact apple about it and have just learned to live with it.
 
My 2010 27" iMac was fine on Lion until 10.7.3. The wakeup on this iMac is sporadic, it will work and then not work using the trackpad or mouse. Always works using the power button. I also updated a 2006 24" iMac and a MacBook with 10.7.3 and they are not having any wakeup issues at all. I have an open problem # with Applecare and they had me capture some files and email them to engineering. A call back stated they were working on a fix.
 
I very very rarely have issues, apart from very occasionally the AirPort seems to be working fine, though my web pages seem to refuse to load, even though my iphone is connecting fine. After turning my mac off-then on again the problem corrects itself.
