Good Morning Everyone

 

This problem has stumped me.  I had a system that was working fine for about 6 months.  We have the latest 27" iMac at home running on the home WiFi system that is using a Airport Extreme to connect to the internet, and I have a MacBook that I use around the house.  These two, plus the iPod Touch that we also have would connect and run fine over the system together, untill last night.

 

My wife was using the iMac watching a movie from Netflix, when I got home, and I went to open up my MacBook as normal, and as soon as I opened the MacBook, her connection on the iMac stopped and I have not been able to get it back online since.  This is just strange, I can use the internet fine with the iMac, but the MacBook is not having any of it.

 

I can open up Airport Utilities in the iMac, and it see's the Airport Express, and the green light is on, but the link to the internet is yellow, so I think that is the problem, but why can the MacBook connect via the same Airport Extreme and not the iMac?

 

Any idea's guy's?  I am not that techie, so basic very basic please.

 

Thanks

 

Pete

    Since it is only the iMac that appears to be having difficulties, I would suggest taking a look at this Apple Support article to see if it can help you. Although it was written for OS X Lion, it still applys to Mountain Lion. Please post back your findings.

     

    Also do you have an AirPort Extreme or Express or both? If you have multiple AirPorts how do you have the configured? That is, is one extending the range of the other or just being used for iTunes streaming/sharing a USB printer?

    Just to make sure I understand. Is your Netgear your "main" Internet router? That is, is it connected directly to your Internet modem? ... or is it the AirPort Extreme performing this role? Regardless what is the model# of your Netgear router?

    If your Netgear has both NAT & DHCP enabled (i.e., it is performing as a router), the AirPort Extreme should be reconfigured as a bridge. That way, any network client connected to either router would still be able to gain Internet access. Do you have the Extreme configured as a bridge?
