    I found a solution.


    Had a similar problem on my White 2008 Macbook:


    Wifi was connected ( to TL-MR3220 BGN Router ), but sometimes webpages wouldn't load, connections timed out, skype froze. Altough Wifi was connected with strong signal.


    It was definitely Lions fault, because another White Macbook with Lion had the same problem, while all iPhones and Android phones kept a stable connection at all times.



    I solved it by simply changing the Wireless Mode on my router from "N" to "G".

    So now I only have 54MBit Wireless instead of 130MBit, but the connection is completely stable.



    Hope this helps someone.

    My router has only B/G and it was dropping continuosly. You are lucky.


    My actual set-up is still working. Yesterday my provider had a problem and the usb modem supplied the connection perfectly and when the provider restored the connection, tp-link switched automatically back to the ethernet connection.

    About six hours ago  I had a disconnection but I cannot tell what was the cause. I needed to carry my MBP to the kitchen to read a recipe I was preparing, so I unplugged the power cord and the mac immediately switch off. I had to reconnect the power cable and switch it back on, but the wireless connection refuse to work. Both the router were functioning, all parameters were in place and I was able to log in into both, so I rebooted the provider router from within itself and in a few second the connection was up again. I didn't watch the connection before unplugging the power cord so I cannot tell if the interruption was caused by the same old issue or it was a coincidence because of the MAc power off.

    Anyway, let's assume for now that it was the power failure, therefore we can say that we are now at day 4 without any drop out. good.

    I seem to be able to replicate your problem by either turning off my computer or unplugging the modem. Other than that the darn thing just keeps working all day on all computers running Lion. Can't understand it!

    Hi There - im having same problems as all of you with my Router Zyxel P 2602 - D1A. Question: do all of you with Apple Airport Ekspress or Ekstreme have wi-fi "timeout" problems? Maybe the solution is to buy an Apple Router...? PS Haven´t read the whole thread...  PPS: as i try to post this - i have time out!!!!!

  • Carlo TD Level 3 (550 points)

    being timed out represents a setting that needs to be channged both on the computer and on ther router (i am thinking.) There is an answer about 4 pages back.

    I have a circa 2010 iMac and a Motorola Surfboard SBG901 (less than 2 years old) modem/wifi router all-in-one; and I experienced slow/irresponsive internet with Safari over wifi only with my iMac since upgrading to Lion.  (all other wifi connected devices worked fine)  Same slow/irresponsive internet also when the surfboard was plugged directly into my machine.  However, I did notice that when I logged onto to talk directly to the surfboard, it was was just hung up talking to the internet. 


    I did probably all the "fixes" or "tricks" that have been discussed on this thread, none of which worked.  I made an appointment with the Genius Bar...and when I brought my iMac into the store and logged onto the store's wifi it was working like nothing was wrong.  The Genius reset my network settings and my PRAM, it continued to work fine while in the store.  I got improvement...same slow/non-response. 


    So, at my wits end..this weekend I purchased a new modem with DOCSIS 3.0 and an Airport Extreme.  Believe me, I wasn't thrilled with a $30 software upgrade resulting in a $300 hardware upgrade as well, but my iMac is back in business and it's great to have it back!


    Therefore my conclusion is that the iMac doesn't communicate well with "older" modems or routers or, in my case, the SBG901 that I owned.

    I finaly found out what the problem is! it is a Router issue you need to make sure your router sends out only one signal like B or G only not both that proberly is conflicting with OSX 10.7.

  • iRik1988 Level 1 (0 points)

    ***Updated*** With the G setting only on the router can't conect to my ipad and iphone so the setting are back normal the issue remains unsolved, hope Apple inc. Does atleast know we have this issue and hopefully fix the issue in a future fix becouse SL had none of those stange wi-fi issues.

  • Carlo TD Level 3 (550 points)

    yea your not making sense... yes the ipad works with G... and yes Apple is using the latest.... sorry to hear your old router was not up to speed.

    Personally I think there is more than a router issues when it comes to Lion and the wifi.  Keeping with full disclosure I did replace my home router with an Airport Extreme and I am very happy I did.  But, I spend a lot of time in Korea and I have a small 4g pocket router and I never have any trouble staying connected with it.  It's not an Apple product and it works well with my MBP.  My point is that macs should just work, with any router any where!  Thats why we became mac users, no more DLL issues and blue screen crashes.  So I think Apple has more work ahead of them to make Lion work as seamlessly as nearly every earlier OSX has in the past.  Tiger no problems, Leapord no problems, Snow Leapord no problems, and then Lion which seems to be flawed based on the ever growing number of pages on this forum.


    Just my humble opinion.


    Good luck and hang in there a permanent fix has to be coming.


    Okay I'm off to another hotel and router.

    The most frustrating part of this whole thing is that support calls with Apple are simply a shoulder shrug: "Surely it must be YOUR network configuration."


    Apple cannot continue to live on street cred when you release a dud like Lion.


    I work in a large Law School and have had nothing but connectivity issues when our students upgraded to Lion. There is a small minority that has Lion working OK (note it's just OK, it still takes turning on and off the Airport to regain connectivity). After many, MANY support calls, we always end up at the same point to where they suggest reconfiguring our ENTIRE network simply to support Lion.


    This is NOT a solution.


    In addition to the 400 or so faculty, staff and students, the undergraduate side is having the same issues that extends into the 3000 person student body. We've experimented with a number of changes and each one has adverse effects on PC users and Macs pre-Lion. I'm shocked that numerous forum threads with posts into the hundreds hasn't gained national attention like Windows Vista.


    We are not going to reconfigure our network to support a single OS when every other OS is working fine (Snow Leopard, Windows XP, Windows 7, EVEN Windows Vista). Currently we recommend both Dells and Macs to our students and if this issue isn't fixed soon, Macs will no longer be a recommended model.


    (Also thought it was hilarious I couldn't sign to post from Firefox, only from Internet Explorer)

  • BenHart67 Level 1 (0 points)

    Also, we've tried EVERY fix in every thread from resetting PRAM to totally reformatting the machine with the combo update. Nothing works.


    We've started downgraded people to Snow Leopard and they are extremely pleased.

  • Carlo TD Level 3 (550 points)

    networking is about numbers matching numbers. nothing to do with operating systems. If you are the admin of the network, you should see if there is a firmware upgrade.

  • Carlo TD Level 3 (550 points)

    I think that is a shame... your a network IT person... and you are thinking of downgrading because your not profiecient... what a shame for your school.

  • BenHart67 Level 1 (0 points)

    We have tried a number of things and without severly compromising other things, there is no sure fix.


    I also refuse to continue to troubleshoot our network when it's obviously an OS issue. There's no reason that Snow Leopard should work normally when Lion doesn't. That's not OUR issue, that's Apple's issue.
