    Have now disabled the wireless (I had turned it on a week or so back prior to upgrade to Lion to do some testing). The Ethernet RJ45 is now the only  connection and iTunes no longer drops in and out.

  • MarkBarton Level 1 Level 1

    Me too.  Since installing Lion, wifi drops after inactivity.  Need to re-select wifi network frequently and wait 30 seconds each time.

  • Tommy2er Level 1 Level 1

    Same issue as this. Was using SL two days ago, no issues at all. Internet ran fast and had no dropouts. I install Lion, and now my Mac drops connection at random times. Sometimes it will stay connected for upto 5 minutes, other times its dropped connection after 7 seconds (no exaggeration there either, that actually happened).


    Really quite dissapointed with this. I'm not a tech guru, but I do know that something has seriously gone wrong with the testing of Lion. What kind of an upgrade takes a perfectly functional machine and makes it worse?


    Is there any news of a fix in the works for this? Or is there a way I could restore my Mac back to SL for the time being?

    Same issue with me, however, not only does my imac (with lion installed) lose connectivity but also my mbp (with snow leopard) does too.  Not only that, but my iphone (3gs) and my girlfriend's iphone 4 (verizon) does too.  My issue seems to be after the computer goes to sleep.  i've read a post that the user tried to increase the time before their computer sleeps but to no avail.  i'm trying this anyway.  very frustrated.

    Hi, wifiguru,


    Just wanted to let you know that throttling back the Belkin N1 to just HT20 worked very well. Once the connection is made, my iMac stays connected until the power saver settings kick in. Much better than  before. It's still annoying that I need to reconnect twice a day, but at least it's livable. I'll wait now until the Geniuses come up with a revision that improves the improvement.





  • jlbr Level 1 Level 1

    I vave the same problem, specially when using iTunes Remote speakers. WiFi drops out many times. Use to work perfect with Snow Leopard.

  • maltwom Level 1 Level 1

    Exactly the same problem.  Absolutely fine for over a year with SL, nightmare with Lion.  Drops every 5 minutes.


    Praying for the update from Apple - simply unable to use internet until the patch is released.  Come on Apple!

  • umbeXXX Level 1 Level 1

    Probably I found a solution:

    starting Lion in 32 bit mode holding 3 and 2 key at boot time, it seems that wifi drops no more, or very rarely.


    With standard 64 bit mode it was a real nightmare... in 32 bit I'm able to respond to this forum without any issue...


    Try out this trick and let me know.

    I'm staying in 32bit mode till next realease from apple..

    Same here

  • wifiguru Level 2 Level 2


    if all your devices are dropping the connection, then the issue is most likely your ISP.

  • wifiguru Level 2 Level 2

    Glad it worked for you.

  • wifiguru Level 2 Level 2

    Here's a list of things that have worked for some folks. New poster's should try these step's to try to fix their issue:


    -Reset SMC. (

    -Backup and then delete the files in /Library/Preferences/SystemConfiguration/ directory. Reboot your machine after this. This will delete all network preference's.

    -Check if you have the firewall enabled. Disable it. Delete this file: /Library/Preferences/ Reboot your machine.

    -Check if you have any kind of antivirus installed. eg. Avast etc. Uninstall it.

    -Check your DNS settings. Use a known good DNS like and

    -If you have multiple Location's set up in Network, try deleting them and only picking Automatic.

    -When your connectivity drop's, ping the router and see if that work's. The issue might be with the ISP.

    -On your wireless router, pick a cleaner channel. If using 2.4 Ghz, use HT20 only.

    -Pick WPA2-Personal and your preferred security. If that does not work test if Open/No Security works.

    - If you are using a 5 Ghz channel, pick ch 36/40/44/48 and try if it works.

    - Make sure the beacon interval on your Access Point is set to 100ms.

    -Make sure the Mac see's the AP at a good signal strength. -35 to -70 is a good range. Hold down the Option key and click on the WiFI Menu Extra for this info.

    I have issues only with Lion: in the same network Win7, 2 iPhones 4 an Apple TV work flawlessly.

    Yesterday half an hour to print a documento to my wireless printer through Lion.


    So ok for temporary workarounds, but I think that this is a primary BUG that has to be fixed as soon as possible.

    This night I will move my rooter near to my iMac and wire the ethernet... So probably I will have a stable connection...


    No one from Apple here? I would like to hear an official response for this problem...

  • Justin Green Level 1 Level 1

    I've tried a few of the options here (thanks to everyone for the info), I think I will wait until Apple sorts this out, hopefully a software update this week, failing that, I'll go back to Snow Leopard where I had no problems at all.


    What bugs me (slight joke there) is that they go on about Lion doing this, doing that and looking all fancy. They can't even get the basics right, Apple used to be about stability which we mostly buy Apple products for.


    I'm still trying to work out what is so special about Lion.

  • toddfromexton Level 1 Level 1



    It was working for two full days, then I went and turned Time Machine back on to the Time Capsule and its fubar again. I have f**king reset everything (Airport default, SMC, PRAM, turned off Time Machine) nothing.


    I know its not a problem for everyone for the few like us on this discussion Lion is an epic fail so far.
