    This is an Apple problem through and through. It has nothing to do with what channels other wireless routers are on or the position of the aluminum case. The only time the wifi operates reasonably well is shortly after I restart or start from a full shut down. Performance degrades from there. Often the network diagnostics show red lights for ISP, Server, and Internet. Occasionally, Network Settings gets the red light too. But other times I am fully greelit on Network Diagnostics, but when I check the Activity Monitor there is a zero rate for sent/received or some ridiculously small number of bytes. From the many bizarre and arcane proposed solutions I have seen suggested, the only thing missing seems to be human sacrifice. Now why would I say such mean things? Because PCs running on the same wifi system operate at roaring speed. And I am thoroughly infuriated because like all the opther unfortunate posters, I bought an iMac expecting a better experience that a Dell would have provided. I have read numerous posts about this problem, and the glaring thing that is missing is an honest response from Apple in which the company admits responsibility and offers to fix or replace the many defective products they have pushed into the marketplace. Very, very disappointing. Just another corporate one-finger salute to consumers.

    I have found a solution that has absolutely worked for me and hopefully will work for the rest of you.  This was an excerpt from OSXdaily.com, which addressed the issue and presents a new solution that has solved all of my connectivity problems.  Here is the routine:

     

    Before proceeding, make sure you have done the following:

    • Be sure you are running the latest version of Mac OS X ( get 10.7.2+)
    • Apply all available system and software updates available to your Mac from  Apple menu > Software Update
    • Reset the WiFi Router

     

    After you’re positive you’re on the newest version of OS X and have all software updates applied to the Mac in question, proceed with the solution:

     

    Add a New Network Location & Renew DHCP Lease

    • Launch “System Preferences” from the  Apple menu
    • Select the “Network” panel
    • Click on the “Location” pull down menu and choose “Edit Locations…”
    • Click on the + plus icon to add a new network location, give it a unique name, and click “Done”
    • Back at the Network panel with the newly created location selected, click on “Advanced” in the bottom right corner
    • Click on the “TCP/IP” tab
    • Click on “Renew DHCP Lease” and wait for the numbers on the left to repopulate, then click “OK”

     

    Once you do this, all the issues should be resolved.  This is actually an included fix in Apple's latest OSX update, but for some users their settings may override the fix.  In that case, the DHCP lease renewal would not come into effect, making their connectivity spotty.  Try this fix and let me know if it works for the rest of you, because it definitely helped me!

    I tried this a couple of months back and it doesn't work for me.  I also just tried there again (just in case) and again it doesn't work for me.

     

    Come on Apple I have had this problem for months now, this machine cost £1000 and getting connected to the internet is an absolute joke!

  • tractor22 Level 1 Level 1 (0 points)

    Add me to the list of 27" iMac with dropping wifi. My roommate and I have 10 devices (PS3s, Droids, iOs, Windows 7, etc) and this is the only device with any sort of connection problem.

    Puuuuuuhlllllleeeease Apple come up with patch to fix this issue!

     

    We don't pay close to 2k for a 45lb paper weight.

  • Andreas Carlsson Level 2 Level 2 (235 points)

    "Solution"!

     

    One of my clients have had this problem since they bought a 27" iMac a half year ago. It's been a real PITA.

     

    Last week they bought a new Airport Extreme Basestation. Since then all problems vanished. They had a two year old Time Capsule before.

     

    I don't want to call this a solution, since I don't think you should be forced to buy a new router for your computer to work...

     

    FWIW.

  • DamenS Level 1 Level 1 (0 points)

    This is not the only reason to be cautious.  There have been many "solutions" which have worked for a week or even a month - none have yet stood the test of time.  One week is not long enough to suggest the problem has truly been solved - even for your client.

  • Informatie Level 1 Level 1 (0 points)

    I had the same thoughts , bought this extreme any YES  the IMAC was seeing the network and then timeout and my WIFI network could nt be found any more so nw wired.  I think before we all go to maountain lion this should be fixed in lion.

  • wapsijim Level 1 Level 1 (60 points)

    Anyone hear of an upcoming fix for the WIFI/Lion problem from Apple?  I've swithced to a wired connection, but would really like a software update to fix this.

    Add me to the list of 27" iMac with dropping wifi! This is so frustrating!

  • Daoakley Level 1 Level 1 (0 points)

    I have had my 27" iMac for about a year. Until about two weeks ago I never experienced any problems with the stability of my WiFi connection. It all started for me when I ran the most recent system updates. When I installed the update, I noticed it included a so called fix regarding WiFi. Before the update I did not have any problems. Since the update the WiFi does not stay connected for more than 15 min. I hate that there is no easy way to roll back updates on Mac. How short sighted.

     

    Has any one had any success with contacting Apple support directly? What are the solutions they are proposing?

  • JudieR Level 1 Level 1 (0 points)

    Here I am again. This is still happening to me.

     

    I have a SHAW Cisco Broadband 50 router from over a month ago - I don't know if that is complicating things but it still seems to just be ME mostly and my 21" iMac bought new last summer.

     

    Yes, it's still under warranty and I'll be getting Apple Care for the next two years but seriously .... does anyone really think Apple can help me over the phone? Or even if I take it in? Doesn't everyone here with a new iMac also have Apple Care or a warranty? So, has anyone taken your iMac to the shop under warranty and actually gotten the problem fixed?

     

    I keep thinking it's just me until I come here to vent and see that it's still happening.  It's maddening!

     

    sigh...............

     

    But I think it's also my router from Shaw because I'll Airplay songs to my Apple TV and they'll stop after a few - so that's not my iMac, it's the wifi. So maybe it's also Shaw ....

     

    Maddening..............

     

    Judie

     

     

    Edit:  I just realized that when I play RADIO stations on Apple TV I never have a problem with songs cutting out. So, wifi must be working for me to get the radio station, right? So, it really can't be Shaw because 99% of what I do with Apple TV involves listening to radio and having my screensaver running so I can view my photos. But today it was happening when I Airplayed the songs from my iMac to Apple TV. It's happened about 4 times so far in an hour. :E  grrrrrrr

    From what I understand, many of the supposed "fixes" and "solutions" are the product of Apple support and their so-called "geniuses". Here is the simplest diagnostic for all of you fellow sufferers out there: try a pc on your wifi. I predict it will give you the blazing speed you are paying for. While I appreciate the various workarounds people have offered here and elsewhere, Apple has clearly put a defective product into the marketplace which has caused significant financial damages. Think about the amount you invested in the iMac PLUS what you pay per month for broadband that you can't use. Based on the number of complaints I have seen on various boards, I am just surprised there is not a class action lawsuit addressing this problem already. I am going to start trying to identify some of the law firms that have brought suits concerning other issues. As much as I hate seeing the jackals of the class action bar get fed, this situation is clearly all kinds of wrong. Sadly, Apple seems to have no interest in fixing it, which I guess means they have reached the big time: shoddy quality is an accepted part of their business model. I wonder if too many resources have been diverted to iPads and iPhones, pushing laptop and desktop problems and quality to the back of the queue.

    Just wanted to mention that I had a 2 month old 27inch iMac.  I tried several suggestions to solve the wireless problems... called Apple and they mentioned it was probably interference.  That was not the case, i brought it into Apple store only to find out directly that Apple has recognized a definite issue with the wireless connection, specifically with 27inch iMacs.  They don't have an official fix at this time, there may potentially be an update soon to solve the problem. 

     

    Its very frustrating, but they were helpful and willing to negotiate in attempt to make up for the problem.  It seems the only way to improve the connection is by getting the Apple router that is specifically made for the newer models. 

     

    I would suggest bringing your computer to Apple if you're experiencing the issue and work something out with them.  And for those looking to purchase, I'd obviously stay away from the 27inch iMac for now, its a very annoying problem.

     

    -I returned my 27inch today for another model that is not experiencing any issues.

    Ok, I did a speed test on Shaw with my 21" iMac (10 months old) and instead of the 50 M d/l speed I'm supposed to get I got 12.36, 13. something - both tonight - and 10.something and 9.something this afternoon.

     

    I just checked my old iMac (2007) right before the new one tonight and it got 44.61M d/l speed. They are both on the same wifi network and the same thing was running - Apple TV.

     

    The ping is always 83 ms.

     

    Just tested my iPad twice - 42 ms ping - 27.37 and 29.something - and 3M upload speed. Apple TV still running.

     

    Tested new iMac again - 82 ms - 13.13 d/l - 2.64. My iPad is doing better than my iMac!

     

    And here was me thinking it was Shaw!

     

    Just bought my Apple Care Warranty for the next two years. I guess this thing is going to the shop. Right after I try the fix Shaw gave me tonight - changing the wireless modem. What have I got to lose!

  • JudieR Level 1 Level 1 (0 points)

    Got an e-mail from Shaw with instructions on how to go to MANUAL and change channels instead of being on AUTO and wifi protected.

     

    I tried many channels just because I was curious. My highest speed was 37.66M d/l. So I am satisfied with this for the time being. My old computer is getting a bit less but my husband uses it and he doesn't care!

     

    I don't understand why my husband's iMac (the 2007 one) has a ping speed of 42 and mine is consistently 82/83. Is it because his iMac is closer to the router?

     

    Anyway, the wifi has continued to go on and off all day long for weeks now so I'll see if this channel change does anything to stop that. If not, I'm taking it to the shop as soon as my Apple Care arrives.

     

    I'd love to return this 21" iMac for a new 27" one - hahahahahaha.    Don't know if they'll take it back and give me a new one when it's nearly 10 months old.

     

    Oh well, whatever it takes, as long as it gets this wifi issue fixed.
