I inherited my Dad's imac and am having problems with the built in wifi. I got the imac to connect with an old airport express which is connected to a netgear router. The airport icon in the upper right hand corner shows a strong signal yet I can't seem to connect to the internet. My ipad has no issues. When I try to go anywhere on the internet, the browser trys to connect and then times out. When I connect the imac directly to the router, it works fine. So, basically a hard wired ethernet connection works but the airport wifi does not. Any ideas?

iMac, Mac OS X (10.6.8)

    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: 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 tried the assist me/diagnostics. It said my internet connection appears to be working correctly yet the network status said failed on the last two radio buttons. Those being internet and server. The first 4 are all green.


    Read Netgears user manual and/or contact their tech support.  Or contact your ISP.  Your router & iMac network settings are not in sync w/each other.

    Network wifi & ethernet have different settings.  Your problem is w/your wifi settings between your router & your iMac.
