Q: imac wifi not working, not the network

I have a late 2009 Imac and the internet was working great on it and everything seemed good, then all of a sudden It stopped working.

 

It shows that the computer is connected with full signal and I even ran the diagnostic's on the network and it stays red on the ISP dieod and flickers green once in awhile, after reseting and unplugging the router a few times reseting the modem and and also reseting the PRAM I have had no luck

 

I managed to get google to pop up for a second and then  nothing and I really mean only a second

 

I ran a Clamscan on it and it found 2 bad files that sad they were trojans and I removed them.

 

I opened up safari and the screen on stays white and there seems to be a skinny grey line that goes up the center of the page vertically, it stays only for a seconed and then disapears.

 

I have my iphone and 2012 Macbook pro retina hooked up to the wifi and it's fine on all other devices.

 

 

I would like to thank everyone in advance for helping me out on this

 

Help me please Im out of Ideas

 

It's very appreciated.

iMac (27-inch Late 2009), OS X Mountain Lion (10.8.2)

    I even ran the diagnostic's on the network and it stays red on the ISP dieod

    Have you contacted your ISP?

     

     

    =========================

     

    Try the basics first:

       Change your router channel number.  Most times this works & is all you have to do.

     

    Disconnect & reconnect your modem.  unplug it for about 10 seconds.  Plug it back in.  Do the same for Apple’s routers.  Wait for everything to reboot.

     

    System Preferences>Network

    Click the Assist Me button.

    In the next window that pops up, click the Diagnostic button & do the necessary.

     

    Research Knowledge Base for network problems that pertain to the OS that is currently installed on your computer.   See these basic networking KB Articles:  http://support.apple.com/kb/HT1401 AirPort troubleshooting guide

    Also, run the Airport Utility app which is located inside the Utilities folder.

    If using a  Linksys router, contact LinkSys Customer Support and/or post in their forums.

     

    If using Apple's Airport, please re-post over in one of the AirPort Forums.

    I have changed the channel on the modom and I called Time warner and the technision changed the Ipp address and googled fired up clean and the I even tried cnn and it worked great but I noticed it was allot slower.

     

    Then I got off the phone with him and the problem reverted right back to the way it was to begin with.

     

    I can't open up any pages and it shows it's connected but the progress bar at the top where it shows it loading stays in the blue and dosn't do anything and no websites come up,

     

    I did a Ping test and the test is showing 80% data loss before I called the tec and he changed it and then all of a sudden it dosnt connect at all.

    Connect to your router with an Ethernet cable, if possible, and turn off Wi-Fi. Any difference?

    it works when its directly connected by ethernet.

    I came home tonight and turned on the computer and I was delighted to find out it was working but it stopped working after ten minutes so i brought the modem in the room and hooked it up and it works as thou nothing is wrong.

     

    What can it be?

    I'm having this exact same problem.

    Late 2009 27" 2.66 iMac.

     

    Wifi working for Macbook Pro, iPhone, and Apple TV, but not the iMac.

    Had been working fine, then quite just days ago.

     

    Restting the modem does nothing.

    Also, the iMac shows full bars for wifi.

    You posted in an inactive thread.  It's generally better to start your own Topic, rather than adding onto an existing one.  After you have tried ALL of the suggestions in this thread w/no luck.....

     

     

    Please start a new topic about your issue so it can receive more focused attention. 

    Please detail ALL you have done so far in the way of troubleshooting?   Need this info to avoid the been there done that scenarios.
