27" imac wifi problems (intermittant)

I really wish Apple had email or online support...

I have a 27" i5 imac that I bought just before Christmas, I had lots of problems with the wifi on it, it would not connect and when it did it was very slow, all while my macbook and iphone in the same room showed full signal and a fast rock solid connection. I rang Apple support, it took ages but they were very helpful and eventually we solved it and in the end it seemed to be WPA that was the problem and whilst I was not happy switching to WEP it seemed to work so I went with it.

Fast forward a month or so and I have started having problems again, it is fine when I boot but as the day goes on it gets slower and slower before finally refuses to connect at all. I am wondering if this could be something over-heating but in truth I am puzzled.

Anybody else having issues?

imac i5 27" and macbook, Mac OS X (10.6.2)

I am having the same exact problem. Bought a 27 inch iMac about a month ago, the wireless connection was a little slow off the bat, but then I was able to fix it. Recently after turning it on the signal is picked up fine for about 15 minutes and then all of a sudden the airport can no longer pick up any wireless network. Meanwhile my iPhone and MacBook have no issues. I called apple support and they had me complete a litany of useless diagnostic tasks - emptied my cache, did a hard reboot, repaired disk permissions , etc. None of it helped. Seems it's a hardware issue. Anyone know if this is a known issue with this model? I'm afraid the airport card itself may be defective in some way.

Also, no offence meant here. But to those who are buying new routers and saying that it's the routers that are the problem, what are you doing to us? You are taking the blame away from Apple, it's clear everything else works on everyones routers and it is NOT a router problem. Pages and pages of people saying the router works with everything else including other Apple products so I am pretty sure like others this is an Apple problem and not a router problem. Please please don't link your own router problems to those of us who don't have a router problem.

I cannot believe there isn't a resolution to this yet!! I had tried all the suggestions in the early days of this thread, even reverting back to an older version of the driver. I thought it had improved but now it is terrible again. It drops many times an hour and is completely unreliable. I can work on my Macbook Air on the same desk and have no problems. This is infuriating!!!

Dear all,


Yesterday I received a phone call from 'Executive Relations'; a very nice lady calling from Cork, Ireland. She was very apoligetic and wanted to help me. Within 3 hours I had another call from a 'senior specialist' - Tier 2 support, the good stuff. This chap was again based in Cork. We discussed many things about this issue and to be honest, I was impressed that my email was read and acted upon. Whilst no solution has been reached, it was helpful to talk things through. I felt he really wanted to get to the bottom of the wifi issue I am experiencing.


Clearly the issues we are facing, whilst on the face of it may appear to be the same, are not. My issue is Apple software related, and most likely down to the OS. I migrated over from my old iMac 24. Those of you who have resolved the issue with router upgrades are experiencing a different issue.


I'll keep you posted of the outcome.


Good luck!

Vishal,


Thank you for the report. It seems rather rum for Apple to pretend it is not aware of the rather widespread wifi issues with recent vintage iMacs and/or their software. It certainly makes me suspicious when I read a post like yours, where there appear to be some unscientific leaps and bounds.


What puzzles me about your post are a) the conclusion that your issue is software related since it was not resolved; and b) the apparent suggestion that others with the same issue may not have the same problem. Granted, one might have a router problem too, but presumably everyone who has migrated to the current OS and updated it would face the same software problem. A hardware problem, which may or may not also exist, might be expected to be experienced with less frequency due to the possibility of a batch or two of some defective components.


If you can expand on what you learned from Apple to support a) and b) above I would appreciate it. Frankly, I question their good faith in this and perpetuating the idea that it is due to lots of unique problems helps them, not us, from a defective product legal standpoint.


Thank you.

It makes really me wonder when somebody is so hypocritical. Let's discuss your own "unscientific leaps and bounds" for a moment. You are "puzzled" by the "apparent suggestion that others with the same issue may not have the same problem". The use of the word "issue" here is imprecise. It is clear that people may be experiencing the same end-result, and yet not be experiencing the same "issue" due to the causes being different. Imagine 3 men who cannot see anything; one is blind, one is in total darkness and the other has his eyes closed ... same result, yet different causes and hence different issues and different problems. What Vishal said was perfectly acceptable, logical and reasonable.


You also seem to equate "hardware problem" with "a batch or two of some defective components" in making your next argument. Could not the "hardware problem" equally be related to the defective design of the hardware, and hence be affecting everyone ? You know, like the design flaw already acknowledged in the previous generation iMac which significantly attenuates a WiFi signal ? What design change did Apple implement in the latest iMacs to counter this - if any ?


Could it not be a conjunction of a design flaw which attenuates a WiFi signal in combination with a software flaw which drops weak signals ? That would also explain why so many previous posts have mentioned the problem does not occur when running Windows on the same iMac (suggesting it is not JUST a hardware issue), that the problem only seems to occur on Leopard and Snow Leopard (also suggesting a software issue), but that it only seems to affect iMacs (which would be a hardware issue). The problem is most likely a conjunction between poorly designed hardware and the way it interacts with SL and Lion software.


It is less likely that Apple will refund everybody who bought an iMac their money due to a design defect when (as Windows proves) this can be worked around with a proper software implementation. It is more likely that Apple may make their efforts to correct the WiFi parameters used within their latest operating systems (at minimal cost to themselves compared to an unecessary product recall).


I for one would personally like to thank Vishal for his/her efforts, rather than criticise him/her and provide no alternate solution or effort.

May 17, 2012 5:24 PM in response to DamenS

DamenS,

I did thank Vishal and I extend a sincere apology to Vishal if my comments seemed critical of anyone or anything other than Apple.


As for your remarks, all I can say is that attacking other people experiencing this pervasive problem is not an answer and your speculation on the universe of possible explanations is no substitute for Apple stepping up to the plate, acknowledging the problem, and promising to make those experiencing it whole.


Also, I used "issue" because that is the word Vishal used, deliberately to avoid being "imprecise".

I was trying to get information on the call he had with Apple support because the apparent identification of the issue as software-related did not seem to identify the issue or solution.


Finally you criticize me for providing no alternate solution or effort. What exactly have you provided other than abuse?


I try not to question the agenda of others who post here. I believe most people mean well and are trying to get information or help others, But in your case I must make an exception.

May 17, 2012 6:01 PM in response to Big Foofer

Do you all see what they have done? Apple has turned us against ourselves, and if we want to win this war we need to stick together. Lol. But seriously, I'm super sour about it too ... I will hopefully be going to pick up my iMac soon from the apple store where they did nothing to it but keep it away from me for a few months. Since I live hours from any apple store this is a huge inconvenience, now I don't know whether I should just take it home or drop it off at the next closest apple store to see if they have any fresh takes on the "issue", but that means waiting another couple months to have a working computer, and they might not call me to tell me that my computer is ready again........ Lemon doesn't even begin to describe this useless clump we all seem to got stuck with. I think that a recall is in order because from what I am seeing this is not going to be fixed, but of course that isn't going to happen either. This situation has gone from weak to super weak, and we are all swimming in a huge pool of weak sauce right now. I hate you apple.

May 17, 2012 7:53 PM in response to Big Foofer

And your hypocrisy continues unabated. First, you are dismissive of Vishal's efforts and criticise him/her, with an aggressive attack containing exceedingly poor logic - which is ironic considering you were attacking Vishal for being illogical ("It certainly makes me suspicious when I read a post like yours, where there appear to be some unscientific leaps and bounds"). "Unscientific leaps and bounds" ? "Suspicious" ? How dismissive, rude and arrogant can you get ?


You state that you are "puzzled" by logical inconsistencies in his post and question how it could be a software problem as he stated.


You then conclude by stating that he is "perpetuating the idea that it is due to lots of unique problems" which "helps them[Apple}, not us, from a defective product legal standpoint".


After this ungracious attack of yours on somebody who was trying to be helpful to the rest of us in this thread, you then you rail against being "attacked" yourself ... Good grief, make up your mind, man !! What is it to be ? You have attacked somebody (well, actually two people now) who have experienced this problem - one of whom (me) was defending the first person you ridiculed in stating that his/her claims and efforts are worthy. If you wish to transfer your erroneous behaviours onto other people this is your issue (one of many I suspect). Clearly you have a slightly "disordered" mind.


Please allow those people who wish to contribute suggestions to this thread to continue without your petty grevious molestations, and you in turn shall be accorded the same courtesies (this is the usual basic social covenant, so you can't claim "ignorance" of protocol). Don't however expect to espouse baseless criticisms of forum members legitimately reporting their efforts back to us and attempt to belittle their efforts without expecting the strong response you have now garnered. If you wish to act like a troll, please do so under a bridge - not in this forum.


Perhaps if you had read more than the last post before you decided to add your critical opinions of Vishal, you would also know what I have contributed or "provided" such that you would have no need to ask this question - unless it were to be just another attempt of yours to criticise and troll, hmmn ??


Vishal's efforts were, as I originally stated, both commendable and logical. It is a pity he had to encounter your ill-conceived criticisms, and if you can't handle somebody else being critical of your criticisms then you are being a hypocrite and perhaps you should consider desisting from such behaviour in future.

Ehlevated,


Sorry for engaging in an unproductive dialog and contributing to the distraction from the problem at hand. I can't offer encouragement, but I do not want to contribute to anyone's discouragement either.


I have seen the same tale of woe about repairs on this board and elsewhere, so for now I am refraining in the hope a real fix comes along or indications of a commitment to make a real fix from Apple. I have also held off on buying a new router because my router works fine with pcs and other devices.


I have tried every fix that I can find, including those posted here and elsewhere (including the one jonathad mentions above), talked with the geniuses, etc., and nothing has yielded more than very short term results, and I wonder if that is just wishful thinking on my part. I have posted the exact network and diagnostic indications I see when the problem manifests. It might be helpful to see more results from others.


Good luck.

Vishal,


I do appreciate your input and sincerely apologize if my post appeared critical of you. I question whether there is logic or science behind what Apple is telling you. My remarks that perpetuating the idea there are many unique causes helping Apple, not us, was directed at Apple, not you.


Also, I really would appreciate it if you can expand on what you were told. I know there have been unsuccessful efforts to address this in software updates, so it would be helpful to know what they may be missing.


Thank you again.


Best regards.

Wow! I go away for one night and this is what happens? Chaps, seriously, no offense has been taken whatsoever. I am confident in my ability to think through problems through logically. I was, in a previous life, a Mac Genius. I have tried to resolve MY issue/ problem - (years of Apple training make me say this always) and whilst I am still without a proper solution, I feel my thoughts and comments have been taken seriously by Apple. I merely mentioned this to try and help others gain access to Tier 2 support technicians.


I am certain it is a software fault, the AirPort card is working. If it was not being recognised, I'd think otherwise. I have booted from external devices and the problem seems to go away, however I have not tested this extensive as I do have a day job. This weekend I'll be creating a partition on my current drive and testing.


As for the squabble that has now begun, please may it stop. There is no need for anyone to apologise, least of all to me. Thanks to those who'd looked out for me, I am flattered and it is very much appreciated.


Yours,

Vishal Vora (Mr.)
