  • Didado Level 1 Level 1 (0 points)

    Like everyone else I'm having the same problem. However, I noticed something I haven't read before. When my iMac with Lion drops the wifi connection all my other Apple devices (AppleTV, iPhone and iPad) are unable to access wifi. In other words as soon as the iMac connection is dropped it seems to take over the router (fritzbox) blocking all wireless traffick. As soon as I turn off the wifi on the iMac the other devices resume the connection. Interesting.

    Like everyone else - I have the same issue since upgrading to Lion.  A slight difference from Didado however is that only my iMac seems to be affected - all of my other WiFi components work fine (iPhone, iPad, mac mini, xbox, dvd player).

     

    I have had a ticket open with Apple on this issue for a few months now - we've tried everything covered in this thread to no avail.  The last update was that this was a recognized issue with Apple and engineering teams are currently working on a resolution.  Here's hoping they have one soon!

    Hopefully the Airport Utility Update just released will help?

  • domenicomusci Level 1 Level 1 (0 points)

    Many people have experienced the same problem with wifi and lion, (iMac 27 "2.6 GHz in my case) I found and solved the problem by lowering the frequency of the access point was set to 20/40mhz with maximum power of transfer to 300Mbps, bringing the frequency to 20MHz and a substantial lowering of the speed at 108Mbps I solved all my problems.

    Unfortunately, I am having these problems AFTER the update...

     

    I've tried many of the solutions written about in this forum.  I'm VERY disappointed in Apple right now...

    had the exact same behaviour on 2 white 2008 MacBooks with Lion,

    timeout while pinging, while at the same time my android phone kept pinging without connection loss.

     

    It was fixed in my case by setting the router to "G" 54MBit speed only.

     

    No more connection loss on both macbooks

  • davidcz Level 1 Level 1 (0 points)

    Same issue.

     

    I've noticed the same as Didado... Since upgrading, when the Macbook Pro wifi drops, then my iPhone drops too.

    My drops are not as frequent as others... Every 2-3 hours, but interrupt the connectivity with other Apple devices.

     

    So as it only happens a few times a night, I've put up with it...

     

    Haven't checked if it is actually affects the wireless router (correspondingly bringing down Windows devices).

  • CocoRallado Level 1 Level 1 (0 points)

    HI Folks,

     

    This is the easiest and most effective way to fix the problem with Wi-Fi dropping with OS Lion ( mostly ) but with OS Leopard as well. I have tried many solutions posted on this site and also on the Goole, but have all failed.

    I decided to buy an external USB Wi-Fi adapter that is Mac compatible, and guess what. Problem solve! I have actually bought two different types of USB wi-fi adapters and the only difference was the size. The first one is made by Iogear GWU625 which is a liite fatter than the othe one made by Zyxel NWD2205. Both of this devices work fine, just have to search for the drivers as the mini cd included is useless on Mac and does not provide you with the right softare. I found out that the Xyxel usb wi-fi adapter is smaller allowing you to use a mouse on a MacBook Pro which ony has two USB ports, and for me makes it easier to use than the standandard mouse pad, the othe wi-fi adapter is a little fatter and won't allow you to use the other USB port unless you use and extension. Both devices work fine, no wi-fi dropping and all this for less than $ 30.00 dollars a piece which is worth. No more headaches or rebooing to get back on the  web.

  • butchybutch Level 1 Level 1 (0 points)

    I was having the same problem ever since installing Lion.

    Took my iMac to the Apple store and couldnt duplicate the problem.

    Decided to buy a new Airport Express (mine was about 5 years old) and guess what??

    No more wifi dropouts.

    I really tried to avoid buying a new Airport Express, but I tried every trick listed here and at best they worked for a few hours.

    Been running my iMac with ZERO dropouts for a few days now.

    So....thats what worked for me.

     

    I suggest you guys try it and if it dosent work just return it.

  • gkillmaster Level 1 Level 1 (0 points)

    same here. same problems since installing Lion. Have spent many many hours trying everything herer to no avail. Even taking it to the Apple store and leaving it twice. They had no ideas ultimately and with the newest update to 10.7.3 and airport utility, the problem is the same or even slightly more heinous. I really can't believe this is going on. Its been months now with no fix in sight. Looks like my only alternative is to get a newer Apple computer.

    Which I will never do out of resentment for this issue. Apple does not have the idea that this problem has anything to do with Lion. I spent many hours on the phone talking to tech reps at Apple and did lots of tests and sending data etc.. but the overall attitude was they needed to do more and more tests and at some point I just felt like they were running around in circles. At one point I purchased a new router (Netgear 3800) thinking it was worth the expense to give it a shot and the weirdest thing was that it was ok for a few days, then eveything returned to its normal broken state again. Something has changed, no doubt and it all leads to Lion not being completely backward compatible. I'm on a late 2007 macbook. My wife has a new Macbook Ait and has none of these problems...

  • David Press Level 1 Level 1 (5 points)

    It's not a backward compatibility issue. I have a brand new (1 month old) iMac and I experience the same wifi drop. Like you I changed my router and things were fine for a few days and upgrading to 10.7.3 has definitely worsened the situation. I may have to bite the bullet and purchase an Airport Extreme and see if that helps. What's annoying that Apple don't even want to admit that there is a problem which there obviously is as so many people are experiencing this issue.

  • joe619 Level 1 Level 1 (0 points)

    David Press,

     

    Not to dash your hopes, but I've had the same problem, and I have an airport extreme.  I have had several mac's use the airport, and some have no problems, while others (only machines running Lion) have this VERY annoying problem. 

     

    But I've also seen the problem with non apple wireless access points. 

     

    Good luck!

  • Naddi_90 Level 1 Level 1 (0 points)

    @David Press: I have a 1 month-old mac book pro 13'' and I have the same problems. For a while now I tried to ignore the problems, becaue it happens just 2-3 times a day in the last 2 weeks...it's very confiusing that the "behaviour" of the dropping is so different!! - some days it's dropping like every 5 minutes, on the other day just once.

     

    @ others:

     

    Are you sure it's getting worse after installing 10.7.3? I havn't installed the updates yet, because I'm afraid that there could be more droppings

  • neil156 Level 1 Level 1 (0 points)

    I too am here because my 1 month old iMac has just begun dropping the WiFi after Sleep.  I have 3 Airport Extremes covering the house.  I just installed the 10.7.3 Lion release along with the 6.0 Airport utility.  I do not believe I had this issue happen prior to 10.7.3/6.0.  Ipad and iPhone don't seem to be bothered by this at all.  Frustrating thing is, I just dumped my Windows 7 computer to go to Mac.  Also have tow Windows XP machines on the same WiFi through the Airport Extremes.  They remain connected no problem.  Very frustrating to have to force it to recognize my Network.  If this adds anything to the mix, upon awakening, there are 4 - 5 other WiFi network signals which the computer can see.  It almost seems as if it forgets what network it was previously attached to before it fell asleep.  Again, didn't see this issue before 10.7.3 release.
