Wifi won't turn on since upgrade to Lion

First of all, my apologies if i make alot of gramar/spell errors, english is not my native language.


Yesterday i've upgraded my Snow Leopard installation to Lion on my late 2008 macbook pro and from the beginning i am unable to start my Wifi/Airport card. The menu bar shows the wifi icon but with no signal bars. When i click the wifi icon and press 'Turn wifi on' nothing happens. System profiler shows the airport card and when i look in Console i can see that the system recognizes the wifi card and acknowledge it's mac address.


What i've tried so far:

- I've created another user account

- I performed a clean install on a second harddrive, same problem

- i rolled back to Snow Leopard and the airport card functions as it should be, this rules out a hardware failure

- I've deleted all files in /library/preferences/SystemConfiguration and rebooted

- I've created a new location with only the Airport card under System preferences - Network

- I've made the airport card inactive and active again


I did found some strange messages in Console but they are not very clear: http://imageshack.us/photo/my-images/718/screenshot20110721at102.png/

Yeah...wishful thinking.... I have a 15" MBP with 8 gb RAM early 2011 model.

I believe you should have a very good case for having the machine replaced under warrenty if you have had that much trouble with it and would certainly be pressuring Apple all the way. It can barely be out of Warrenty and has severly affected your ability to work on it if it has spent so much time being repaired. I had one replced under Applcare after 2 and a half years because of frequent and repetetive Logic Board problems. You could also write the details of your problems and send them to your local Ombudsman or Consumer Affair.

Oh wow- I never thought of doing that. I think Australian consumer rights are pretty good, too. If I just mention my rights maybe that will push them into replacing it. I don't know- last time I went in I complained to them that I can't recommend apple anymore (I am in an office of Apple haters who give me sh*t for owning hipster products :]) and that it's severely impairing my ability to work. Especially given my time machine backups are windows incompatible and I have no access to other mac computers here. My timid and polite nature really stabs me in the back. I've been to apple care maybe 6-7 times? Leaving my computer there for repair 2-3 times for up to 5 working days. Glad I got apple care (even though I would rather not give them more money)- I'm approaching the 12-month mark. I have filmed the graphics problem as proof.


Thank you very much for your advice and ideas. Appreciate it

Im in sleepy Perth. I'm so ashamed. I'm such a pushover. They insisted they replace the logic board again because the problem was definitely the graphics card. For good measure they're replacing the screen too. In effect, I am a woman with no balls

And a computer that does not work. Make a point that for all the money they have spent fixing it, it would have been much cheaper to replace it after the first few major fixes. I just stood my ground and told them the MBP was faulty when I bought it and there is a limit of how many times they can call a fault on it and try to justify that fixing it is fine. Contact Consumer Affairs, but first ring Apple, make a firm complaint, tell them you are going to make a complaint as you bought the product in good faith as a high quality machine, and it has basically had the entire insides replaced, some on numerous occasions and you seriously wonder how you can trust that machine for any serious work in the future. It simply is not good enough.

These are wise words, thanks. They said they didn't have the authority to change my computer and that I'd have to call AppleCare, who are currently closed. I felt like I was pretty firm at the time, insisting on a replacement several times. They have just called me to say the machine is ready for pick up (took them an hour, I'm apparently a priority). They replaced the screen, logic board and RAM. I'll call Apple care and make a formal complaint and wait for my next problem. I PROMISE to stand my ground next time :P

What I cannot understand is the failure of Apple (who is obsessed with their public image) to do the right thing by their loyal customers by replacing seriously faulty and expensive tech. I must have spent $50 on parking by now. And the amount of time I've lost at work is inexcusable. When I arrived at the store this morning I checked what changes they had made to my computer. THey had replaced my 8 GB RAM with 4 GB RAM. So I had to wait another 45 mins at Apple resulting in me being late to work again by 30 minutes. Definitely calling Applecare. I will let you know how it goes.

its definatley worth speaking to apple about the issue. i spoke to a senior advisor at apple uk over the phone and they are clueless as to why lion is having wifi problems. i was promptly asked to visit a genius bar with my laptop.


the appiontment is not untill monday but i have now created a seperate partition with the original mac os x dvd installed on it so i can show my genuis chap that the hardware is ok.


will post a full report from the genuis bar on monday
