27" imac wifi problems (intermittant)

I brought my 27" iMac 6 months ago replacing my old G5. I have had this wifi problem from day 1 and have had no help from Apple, both times I had contact with Apple on this issue nothing has correct this problem. I cannot understand the lack of concern that Apple has shown on this issue. There are hundreds of customers with the same problem, if not thousands! This must be extremely bad publicity for them and is enough for potential customers to go elsewhere. All I would like from Apple is to admit there is a problem and that they are working on a fix surely this is not to much to ask having spent many hundreds of £'s on an Apple product. Apple may be not be concerned but a ruputation for poor customer service is very negative and could eventually have an adverse impact on business.

Please Apple let us know what is happening, you have many very frustated customers that are looking for some support from you!!!!!

😠

Dear IMAC,

I think we should make this issue More public other forums and soon .

They are pushing the new IMAC in a few month and also mountain lion.

I would like to use airdrop and move my expensive imac to another room.

I found this on another forum http://forums.macrumors.com/showthread.php?p=14682095#post14682095

BTW, I am quite sure it has to do with the router - the problem started only when I switched a router. The thing is, the router is what comes with my (new) internet provider, and I have no control over that, unless I start getting into all kind of technical details which I'm not familiar with and I don't want to waste time on. Since the router by itself appears to be OK - it works with a few other computers, wireless as well as wired, it looks like the issue is compatibility between the iMAC and the router, and this I expect apple to solve!

Surely it would be more accurate to state it is a problem with Apple's Operating system (At least Snow Leopard and Lion), than that it is a problem with the router - or even "compatibility between the iMac and the router", given that you could run Windows on the very same iMac with the very same router and experience no problems at all.

no, the issue is iMac specific and does not depend on the router: after the latest Apple "fix" it shows on the 5GHz part of my TimeCapsule network :-/

This is product defect, not a compatibility issue. After I start my iMac from a full shutdown, the wifi works fine for a while. When I run speedtests it performs at the speed that a PC performs at. However, after a period of time performance degrades to about 1/20th of the speed. System preferences show that wifi is connected and network diagnostics are fully greenlit. But the activity monitor shows received/sent speeds at a crawl or even a full stop. Then sometimes it does drop the wifi entirely, and I get told to do a bunch of idiotic steps by the Diagnostics panel.

I Have the same issue. The only workaround is to use Ethernet Cable. SIGH.... well at least it wont drops on me now. I do hope Apple found a fix to this problem

thing is i don't have an eth outlet near by. that's why i use the wifi to begin with.

This defect also deprives owners of the benefit of wireless networked peripherals, in my case an expensive wifi-capable laser printer. So it is not just an issue of attaching the ethernet cable to the printer.

I just bought a brand new iMac 27 inch, i5 and having the same Wifi issues. I returned the first one I got and came home with another one because I just could not deal with the problem, I have no DSL cables in the office and need to use the wifi. I was happy with the new one until today Sunday, the problem started on this one, first with the sleep issue, now it just loses connections when ever it wants to. This is a very expensive product and for what I can see it is known for quite some time, I cannot believe this is still happening.

I can confirm it is not the router, I have tested 2 different ones, and my phone, my mcbook air, my ipod, the nintendo Wii are all connected without issue. I even disconnected all the other gadgets but problem still persist. I did everything you could ever do to fix this problem, everything you find in these forums and external one and the problem is still there.

Shame on you Apple. You are just too big to care? I will return the iPad i jsut got out of spite. This really irritates me, especially to see the longivity of this problem and all you have is one airport update that does not really fix the problem.

I just wanted to post about the solution that worked for me. I, like so many others out there, was having unbelieveable issues with my WIFI. I tried averything from these boards that people suggested to fix the issue (tried various suggested fixes for over a month... NOTHING worked). I was about to give up, then decided I'd try one last thing. I bought a new router. IT WORKED. I now have a solid WiFi connection. All my intermmitent drops have ceased and my connection is rock solid. It was so frustrating so I wanted to post this solution for others out there thay may be in the same situation.

The router I purchased was a Belkin dual band N600.

I think the problem with this "solution" for most people is that it involves unecessary expense, it is not guaranteed to work (hope you buy the one magic router to rule them all which does work) and it should not be required. If the same Apple iMac and router we currently own works perfectly when running Windows in Bootcamp, and other Macs with Leopard or older also work without issue, why should someone pay (and pray) for a new router, when Apple could and should just fix the software issue they introduced with Snow Leopard and Lion ?

ESPECIALLY when numerous people with this problem are using Apple's own wi-fi products (which shows it is categorically not a "router incompatability" issue - unless Apple is now designing their Extreme's, Expresses and Time Capsules to not work with their iMacs ...)

It is not the router, I have tried 3 different ones, Apple just needs to provide a fix like Damen says. I had the most frurstrating call this morning with Apple support, I told them about every single change that I had done, how I troubleshot everything possible, how I change iMacs, and the problem is the imac not the router. They want me to go to a the b or g data standard an that means lowering my internet speed which I need for working.

They tried telling me it was my fritzbox, then i told them about the Tsystems router, another netgear and they still will not admit that it is their issue. I ended up speaking to a manager who really could not do aynthing or say anything it is as if everybody at apple has been trained to shift the blame to the ISP or router company.

This might work for anyone who does not know IT, but when they feed this bull to a network engineer it is not going to land nicely. Every single peice of wifi equipment works, even my mcbook air which is running the same os X 10.7.3 as the iMac that is having this issue.

I encourage everyone to blog about it, post it on their facebook and twitter accounts, raise more awareness, then perhaps apple will take responsibility for their problem and provide an actual fix that works.

I've been having these problems too. 27" iMac slow, everything else iPad, iPod touch fast.

The funny thing is internet run fine when I use Windows bootcamp and keeps dropping in the same machine. I tried turned off bluetooth (as I read somewhere saying the interference between bluetooth and wifi signal too) and internet works as well, but then i have no keyboard to use. I've been trying tons of solutions but non of them works, this is really ******* everybody off.
