    I just got a new imac 21 inch, and the problem is there is no airport (top right corner it does not show there)and no wifi enabled, when i go to the system preferences and to network it does not give me the option,  how can i turn it on?

    had been waiting patiently for a wifi fix and happily upgraded yesterday to 10.7.3 and went for the airport 6.0 update as well, guess what? the airport/wifi is greyed out and says no hardware installed plus every programme i open crashes immidiately and have the CUI question marks graphics like on the pic below. had to spend all night doing a clean install from snow leopard and now im staying there. apparently snow leopard is the king of the djungle after all as the lion is dead.

    I also think, have to take step back Lion seems to be angry as we left Leapard

    As always the problem may be any variety of things, as there are several users reporting 10.7.3 fixed their Wi-Fi problems.

    Does this only happen with 5GHz networks? And, does this still happen after the latest Lion update.

    Your problems regarding connection speed might be caused by a wrong (unclear) radio channel. Most of the times automatic channel selection will do fine.

    .......had to spend all night doing a clean install from snow leopard.......

     

    You had no cloned backup? Why not?

  • Harshdeep Singh Level 1 Level 1 (0 points)

    Let me make all things clear!

    This wifi issue has nothing to do with the 5Ghz/2.4 or channel issues or with speeds 150Mbps/54Mbps or with B/G/N standards.

    The reason for that is everything works fine if we just change the OS either back to Leapard or Windows. It is a confirmed bug in Lion.

    I beleive that Lion has got some compatablity issues with all routers, like some said we have changed the router with Airport one, all starts working! The thing is why hardware need to be changed if the bug is in software! silly

     

    This 118 pages thread confirms lacking of Lion OS and should be removed............

    Otherwise perfectly said by iRik1988 100% solution is re-install Leopard

     

    (my free telephonic support is over, otherwise I would have talked with apple men regarding that! Can pay for paid service)

    Have the solution, found it on Answers.com

    I too was **** disappointed to find no wifi connection after updating to 10.7.3.

    How could Apple let that thru?

     

    Try this:

     

    i've been having this problem for over a week n it drove me crazy, but i found the solution! Click on the wifi signal sign, then on "open network preferences", once u're in the network preferences, click on the drop down list in "location", and then on "edit locations" .. and simply delete the old location u were using, it might be "automatic" and just create a new one .. that'll reset ur wifi preferences and it should work like new from there on

    ignoramus .

    what happened Carlo TD...

    please explain in detailed what I have said wrong!

    Really? I disagree.

    Really? Leopard (which came before Snow Leopard) and Windows? REALLY??

    While it may be some modems dont work well with newer standards - standards change all the time (sometimes even overnight). I would think it should be the responsibility of the hardware manufacture to keep up with standards. And if their not, then those modems become incompatible.

    Your inductive reasoning is false.

     

     

    (my free telephonic support is over, otherwise I would have talked with apple men regarding that! Can pay for paid service)

    If it is a compatiblity issue with some routers, because the hardware manufature is not up to speed on standards, then how is Apple responsible to troubleshoot the network or devices of other manufactures let alone if a person tinkers with the nuts and bolts. My answer is this: There could be an unlimited number of reasons why people have wifi issues.  A month ago, you told me you got it working the wifi issue, then it came back the problem. Could tinkering with the settings have some way of effecting the wifi settings. I know you were looking to adjust the MTU also. I also was under the impression you were using a linksis and not an airport extreme. (I dont have a very good memory).

    I dont mean to come across as being harsh and I should not have said your logic was ignoramus. I help peopl too with their networks. (I am not a network engineer but the amount of ridiculious things i see is mostly because of either hardware failure or people not using the latest standards on their equipment to match standards that have been upgraded or are new.)

  • Markus Oliver Level 1 Level 1 (0 points)

    I had the same problem. Solution:

    Reinstalling with time machine update. DL the combo update and updated with it. Worked fine.

    If you need help my email is in my profile. I will be home in 10 hours, and I will be able to help you better.

  • Harshdeep Singh Level 1 Level 1 (0 points)

    Really? Leopard (which came before Snow Leopard) and Windows? REALLY??

    First of all easy easy Carlo...

    I meant to say Snow leopard! ( I thought only writting leopard would obviously indicate to last OS before Lion but you seem to be more specific lolz)

    You have said it here.. trust me never say this to anyone anywhere else hahaha... overnight standards getting changed! really laughing a lot! heard this first time in my career life...

     

      I also was under the impression you were using a linksis and not an airport extreme.

    Dude I am in India and here Airport extreme costs 12k bucks whereas my current router( Netgear DGN150, a US brand ) around 3k. However the purpose of both the products is to transmit and receive wireless signals! nothing hard in it... I was using is when not upgraded to Lion! At that time I was not facing any kind of problem!

     

     

    I will be home in 10 hours

    At that time here time will be 6am, 4th Feb.2012! probably I will be sleeping.....
