MacBook wifi won't work properly

Dear all
Last week I installed Lion on my MacBook. Wifi immediately stopped working properly - I can only connect to the router if I'm 10 inches from it (but the internet works extremely slow), and even then I often get either "connection timeout" or "! No internet connection".
I formatted the whole hard drive and installed Snow Leopard. The problems persist.
I've tried disabling my router's WPA security, with no success.
I've tried establishing an Ad-hoc connection with another computer, and that did work.
And internet is working through Ethernet...
Any help is welcome, this is driving me crazy! Cheers, and happy 2012
MacBook 13''
2.26GHz Intel Core 2 Duo
2Gb 1067 MHz DDR3
Purchased on August 2010

Okay, next idea:
Create a new user account. Log out of the current account and into the new one. Does wi-fi work any better in the new account?
I don't think it will work, but I want you to give it a shot anyway.
Did you purchase the AppleCare extended warranty for this computer?

    Macbook Pro won't start properly... keeps restarting without chime!
    Late 2007 Macbook pro.  OS upgrade worked great for me.
    I have had this problem on and off for a month or so.  I simply cannot figure out what the issue is.  I have tried poerup with and without AC power and with/without battery installed.
    Starting in Safe mode does not help.
    Trying to start with a disk does not help.
    It sort of seems like it might be an internal power issue or GPU issue.
    It also feels sort of like a software compatibility issue since my Macbook Pro gets reallly slugish for no apparent reason sometimes and IU have to restart.
    I have three different anti-virus programs so I doubt it is a virus issue.
    I noticed all this start after I did a Mountain Lion upgrade and then tried to start up VMware Fusion.  Fusion seemed to just bog down the computer horribly but did not cause a system crash.
    I need to edit an important sequence on Final Cut Pro and don't want it to freeze me out!
    Anyone who has had this problem and resolved it please let me know 
    God bless

    If it doesnt chine it doesn't mean much, the mute could be on or you installed a anti-chime software.

    Don't use any cleaning spray. Wipe with a moist but not wet microfiber cloth.

  • My wifi won't work on my mac mini but works on my other devices?

    Ok so I'll try to word this as best as possible. Basically, my family recently got a new wifi network. It works perfectly fine on my iphone, ipad, and all of my family member's macs, phones, and ipads. When I used my mad mini for the first time since getting a new network, the wifi won't work on it. it says i have 3 bars when I am connected to the new network, but when i try to use safari, it won't load. i even tried using chrome so the browser is not the issue. what do i do to fix it? i've already tried restarting my computer and all of that stuff.

    I can't post a screenshot because the internet on my conputer doesn't work. I'll just type it out:
    (Network Name)
    DIsconnect from (Network Name)
    IP Address:
    Router:
    Internet: Reachable

  • DVD Player on MacBook Pro won't work?

    My DVD player on my MacBook Pro won't work! I can hear the sound of the video, but the actual image won't appear. Plus, I can't watch things on Youtube in full screen anymore because my computer won't show it. And finally, some of my images are very pixelated. I'm getting super frustrated that nothing will work. Please help me!
    -Katie

    Many times, these types of problems can be 'fixed' by using a commerical DVD 'cleaning' kit (usually available at local electronics stores, Amazon, etc.). If 'cleaning' doesn't work, you may have a faulty SuperDrive. But I would try the cleaning method first, beofre taking your machine into an Apple Store or AASP.
    Good luck,

  • IPOD won't work properly if drive C: is available on your computer

    The Windows XP driver for the Apple IPOD USB Device has a bug that makes your system very slow or even hang when you try to connect or eject your IPOD if Drive "C:" is available on your machine. Another symptom is that when you connect your ipod, the computer doesn't automatically launch the ITunes app and it is very slow to open manually.
    A typical problem is that if your system has had a hard drive replaced and/or the drive "C" is not assigned for some reason, then the IPOD USB Driver will attach itself as drive "C:" and then it won't work properly seemingly because of conflicts with the Windows OS. Other USB devices never grab drive "C:" but this Apple-supplied device driver appears to think it is OK to use drive C: but then it doesn't work properly.
    The fix is to make sure some real (physical) drive is always connected to or mapped to drive "C:" so that the IPOD USB driver attaches to a drive from "D:" and up.
    Also try reading: http://docs.info.apple.com/article.html?artnum=93499 for more info.

    yeah, the ipod normally gets assigned the f, g, or h drive letters. i don't really know though if windows is responsible for assigning the drive letters to usb devices or the ipod driver. to my understanding the ipodservice.exe only makes sure that itunes can comunicate to the ipod through the drive letter that windows assigns to the ipod. windows is the os and therefore responsible for managinig its drive letters.

  • Since updating to ios 6 my ebooks won't work properly on my iPad. Skips from first page of a chapter directly to first page of next chapter. I'm very unimpressed

  • Keypad won't work properly on 'A'

    I need help about my keyboard. i'm using a curve 8520 on 0S5.
    My letter 'A' in the keyboard suddenly won't work properly.. Just a soft touch and it would appear automatically... in Uppercase. Because of this, i am having a hard time when typing. i copy paste the lower case 'a' so typing would be easy.
    Also, since the 'lock' is also in that key, my phone would always lock automatically and with that... my phone seems to go 'off' and i would have to longpress any key so it would come alive again.
    i tried the application clean-up thing in the desktop manager as @BlackberryHelp tweeted me when i asked them about this but still there are no changes.. i also tried putting a tissue in the back of the metal plate thing. i am so worried coz i just got this phone 3 months ago. Please help me about this! Thank you so much.

    i managed to unlock my phone by keeping power on, remove battery and presto its unlocked. problem is stil letter "a" in keypad is not working can anyone suggest how to fix it instead of going to a technician?
