    Good idea, wclyffe. Done!

    I have a brand new MacBookPro with the same terrible wifi performance. I have tried literally everything on this thread except for a clean install, but there are already many individuals who have done that and it still did not solve the problem.

     

    As I said in an earlier post, leave feedback to Apple. This is likely a numbers game...more people, more action to solve the problem.

    This worked for me!

    Now I am using my iMac in the 5 GHz signal from Time Capsule and doing backup copy normally.

     

    I had tried with re installation of Mountain Lion 3 times and deleting all passwords from the Keychain, but the key is to delete the SystemConfiguration folder. Reset PRAM is not requiered.

     

    I hope this could be the end of the problem until Apple solution is released.

     

    Thanks johnboyuk!

    glad it worked. Just to say - i did try deleting the systemConfiguration by itself but that didnt work for me in isolation - so it was that combined with some/all of the other steps that's the key

    It would be great if you could list the other steps that made it work with deleting the SystemConfiguration folder as I've typically tried a half dozen ideas all separately with no success. Thanks.

    Hi wyclffe - if you look back 6 or 7 posts you'll see my original post that listed what I did.

    Thanks, I will!

    In my home I have a D-link Dir-655 router with which I don't have had any problems, in the office is a D-link WRT54G with which WiFi drops frecuently, reviewing the difference in the configuration I found that if you set the security as WPA2 I have no problem.

    As I mentioned in an earlier post, I have a brand new MacBookPro with the same terrible wifi performance dropping out on a Cisco WAP 4410N at work, but no problem whatsoever on my AirPort Extreme at home. I have tried literally everything on this thread except for a clean install, but there are already many individuals who have done that and it still did not solve the problem. I've even tried johnboyuk's plan of doing several steps all at once, but I still have the problem. The router is configured with WPA2 and no one else is having a problem. Anyone happen to be dealing with this unit by Cisco?

    wclyffe:

     

    This is what I did:

     

    - Delete SystemConfiguration folder.

    - Delete all wifi passwords from Keychain.

    - Delete all wifi conections from Network Preferences panel.

    - Re install Mountain Lion.

     

    johnboyuk said that is necesary to delete PRAM, but in my situation it was not required. My problem was in an early 2009 iMac, with no wifi connection from Time Capsule in the 5 GHz band.

     

    In any case, if you are re installing ML from App Store your Mac must be capable to detect the last wifi connection used and don't ask for a password to use it.

    Thanks, as I think I'm ready to try this with the re-install of ML. What method did you use to lay your data, etc back after the install? I use Time Machine, but of course I'm worried it will lay the problem file right back on the computer.

    The easiest fix for Lion wifi issues is:

     

    1. Create a new user account.

     

    When you have trouble connecting with wifi, log out from the main account you are using, then log into the new user account (you can name the new account "wifi fix".  The new user account should be able to connect via wifi.  If it does (and it always has for me), log out and then log back into you main user account.  You should be able to connect to with wifi at the point.  Yes, it *****...but it works.

     

    Apple, please take notice.  There has got to be some relatively simple reason why logging into a new user acount fixes the wifi connection issue.

    I have a Macbook Pro early 2010 and tried the new user option mentioned above and if fixed my Wifi problems. Prior to this I was not able to activate the wifi at all. Now it works as well with my standard user.

    re: creating a new user account

     

    I wish this worked, but it does not for me. Both accounts are off the internet.

     

    I can tell my router (access point) is tossing me off the internet, but I still have a strong connection to the router itself as I'm only 15 feet away from it. I can simply turn wifi off, then on in the Finder and I'm back in operation. Unfortunately, no one else in the office has a problem...just me running Mountain Lion on my new MacBook Pro.
