27" imac wifi problems (intermittant)

I am also having the same problem on my Mid 2011 iMac 27inch with i7 processor - if I go to System settings/Network/Assist Me/Network Diagnostics it will say my ISP has failed, but I can then reconnect to my network without problems. Unfortunately this is very inconvenient as I am having to do it at LEAST 10 times per day and there are no problems with my 3.1 Macbook Pro (also running SL) on the same Network (although the upgrade to Snow Leopard on this did stop the DVD player from being able to burn on any media type - ironic considering I also have Window's Vista on it and the DVD burns fine through this). In short, I have had nothing but problems since "upgrading" my Macbook Pro to Snow Leopard, and it unfortunately looks like the change to a brand new computer has not been a total solution.

Rather than resurrect a months old thread which is already multiple pages long and will most likely prevent people from reading through all of it, it would be much better for both of you to each start your own thread; if necessary, you can post the link to this one with something like "tried everything offered there, but that did not solve the problem". Tacking onto a thread - old or new - with a "me too" seldom results in helpful answers because each problem is unique; besides, it is called threadjacking.

In what possible way could commenting in a recent thread that one is experiencing the same problems as the other people in this thread be considered "threadjacking" ?? Do you even understand what this term means ?

Besides, if - as you erroneously say by way of explanation - "every problem is unique" then EVERYONE in this thread who has stated they are experiencing the same problem (and there are many) should have started a new thread. This is not how any Forum works.

As has been made clear throughout the course of this particular thead there ARE no "helpful answers" forthcoming (other than awaiting a fix from Apple), so I contest that starting a NEW thread would be even more of a waste of time.

It appears your belief is that a "months old thread" should be allowed to die, when the topic being discussed is of relevance to any person discovering this same problem and conducting a simple search (in which case, why should no-one "resurrect" it, as you call it) ? Archive this thread if you believe it must be closed, otherwise try to present some logical argument for each and any complaint you wish to make about it's continued existence and any further contributions made therein.

"That is absolute fiction. Mine is set to Channels 6 and 10 and works perfectly. And, mine is set to WPA2 and works perfectly. These are with a Netgear router, Motorola Modem and Comcast cable as the ISP. WiMax needs to ascertain facts before making such absurd statements. Maybe higher channels do not work with WiMax, but that has nothing to do with the Mac.

Additionally, you need to remember that on an aluminum iMac, the only place for the signal to actually go anywhere is through the Apple logo on the back. Wireless signals cannot penetrate metal, so there is only a very small area for it to transmit the signal."

Barbara, this is an appallingly ill-considered and unnecessary response to a genuine complaint. If someone has been told that above a certain channel Apple products become "unreliable", you can NOT logically state that this is "absolute fiction" because YOUR particular Mac (sample size you have quoted is 1) has not yet displayed this problem.

I am sure that the MAJORITY of issues (such as the previous iMac Wi-Fi problems, or the Macbook Pro Nvidia GT 8600m) have not been experienced by EVERY user ... that certainly DOESN'T mean they are "an absolute fiction", in fact, even Apple has admitted to them (as I am sure they will eventually do with this current issue).

Secondly why should a user of Apple products "have to remember that on an aluminum iMac, the only place for the signal to actually go anywhere is through the Apple logo on the back. Wireless signals cannot penetrate metal, so there is only a very small area for it to transmit the signal" ?? Why should design issues be a user's concern ? That is a designer's concern. That is a concern for Apple. Whilst one may argue that the screen in an iMac is NOT made of aluminium, your point would be irrelevent even then. All a user needs to know is that their Mac doesn't connect to the internet as advertised and as any other computer has been able to do for the past 15 years ... why should they then say "yes, but I need to remember there's only a small hole for the signal to go through - it's my problem, not Apple's" ??!!

It certainly seems you are a schill for Apple, but attacking a person with a legitimate complaint under the guise of providing help, and with such an abhorent lack of logic, does not behove you well.

You will get more attention starting your own thread, so I was trying to be helpful. Calling my post an attack is more than absurd; calling me a stooge is offensive. Please read the ToU (the link is available at the bottom of every page).

Again, I was trying to be helpful. FYI, I am just another user - no different from any of the other volunteers trying to help here. I have absolutely no power to archive a thread and I did not voice a complaint - it was a suggestion.

Of course, you are entitled to your opinion; however, that does not give you the right to launch a personal attack. I'm done here.

Edit:

P.S. I am assuming your second post was addressed to me although you used a different name within the body of your post.

For me the wireless just goes down after some use, like when downloading larger files. Try downloading (or copy from another computer on the wireless network) a large file, about 1GB in size or something. Tell the support guys to try that too if they have trouble seeing the problem.

Hello, all. I've been crawling through help forums literally for months, trying to figure out why the 'new' iMac I bought my wife earlier this year keeps losing its Internet connection. The connection was totally unpredictable. Sometimes it would work just fine. Other times, it wouldn't work at all. There seemed to be no rhyme or reason to it other than the fact that it seemed to be worse for my wife than it was for me (which we both found weird). I spent countless hours on the phone with Apple Support, fiddled with my wireless router, even purchased a new router and tested it. Nothing worked.

Until today. My wife was heading out for a yoga class this weekend and I was relegated to playing "Mr. Mom" for a couple of hours to our 8 month old baby. The wireless connection was working fine while my wife was getting ready to head to the gym. She had mercifully timed her yoga class to coincide with my daughter's afternoon nap. Right before leaving, she put her down, turned on the baby monitor and handed it to me while I was still at the computer and headed out the door.

Almost immeditely, my wireless connection stopped working.

Then it hit me - the baby monitor. I checked the box and, sure enough, it works on the 2.4GHz band. Our router is also a bit old and is an 802.11g router... 2.4GHz band.

Bingo.

I ran a few tests with the baby monitor and sure enough, I coulid connect to the Internet just fine when the baby monitor was off and when I turned it back on, bam - the wireless connection would go out. I tried it with multiple computers with the same result.

Not sure what we're going to do exactly now. We need the baby monitor for at least a little while longer. I could perhaps buy an 802.11n router and run as much as possible on the isolated 5GHz band and just be careful around all of our devices still running on the 2.4GHz band. Or perhaps find a baby monitor that runs on the 900MHz band.

Whatever the case, at least I know what the issue is now. And after months of frustration, I figured I'd post on every thread I could find where people were having problems with their wireless connection and see if perhaps this could help a few folks out. I realize it's certainly not the only reason why peoples' wireless connection might not be working, but if it helps at least some people figure out their issue, then I'll rest a little easier. 🙂

Brand new user of iMAC product, a brand new 27 IMAC, I burnt my money on it and like all yoiu guys having a lot of issues about wifi disconnection for no reason. HP laptop and iPOD in the same room keeps connection while my expensive iMAC is out of work. What a frustration to have such behavior. Apple is leading what ??? The computer went to repair center and went back, worked well for one day and same problem the day after. I'm really ****** off by Apple. Will move back to windows, cheap and working. Good night. A disappointed Apple customer.

Same here in the Netherlands, bought myself a brand new 21" iMac 1,5 months ago. Never worked on a Mac before, but I like it. On SL at least. After the upgrade to Lion i had the same issue lots of people complain about: intermittant WiFi disconnects. At first everything is OK, but I have pings to my router like 1800ms but after that it looks like all is OK, wifi is up (so the indicator says), but applications are not able to connect to the internet. When i ping my router then it doesn't get an answer back (unreachable), while all other devices in the house are perfectly able to use the wifi at that point.

I have changed wifi channels (used "wifi analyzer" to get the best unused channel) , but still i get d/c's. Hopefully Apple will bring out a fix/update soon.

As a totally new Apple user i am happy with the iMac, but this is a bit of a (hughe) downside. Let's see what Apple is worth....

I bought my iMac 27" 3.4GHz i7, last week and got a free upgrade to OS X Lion.

This also my first Apple product and I had high hopes but right now I feel like throwing it out the window.

I wish i never upgraded because with SL my wifi was working perfectly.

Now with Lion it is terrible.

It's not the wifi directly that disconnects but the internet connection.

My Mac keeps connected to my router but disconnects with the internet.

Went to the iCentre here in Haarlem and they didn't have a solution other than go back to SL.

My old Euro 1000,- PC still connects to the internet over the same router perfectly but this, 3 times more expensive iMac, seems to have problems with it.

It's a beautifull machine and I love it but for so much money it should work without any kind of problems.

Hope Apple will come with a sollution because it's is a well known problem everywhere.

groetjes.

I have been having the same issue - stopped using safari and started using chrome - seems to be working without shutting down. has anyone else tried this? is it a safari issue or am I just premature on this being a fix?

I solved my problem with my iMac staying connected to the internet by going to System Preferences>Energy Saver and un-checking the Wake for network access box. I hope that this helps your problem.

Have been using Chrome all the time. Tried in Safari and Firefox too, no change.

It's most likely not a software problem anyway (atleast not on application level)

Interresting thing to try but no, did not change anything for me 😟

Will hopefully stop my computer from waking upp several times a night tho 😝

As simple as it is...this was my problem. I moved my office around, and sure enough my iMac was facing away from my Airport - and the screen was shielding the wifi signal.
