Hello so before my wifi was switched I was able to use my 802.11g airport express as a wifi card for the xbox 360. I then decided to upgrade my main base station from an 802.11g base station to and airport extreme 802.11n. My problem is that my airport express cant extend the airport extreme network to my xbox anymore because they are different 802.11 versions. So can anyone help me configure this so I can get this back? Any help is appreciated.
My Current Setup:
Internet => Airport Extreme 802.11n => Wireless => Airport Express 802.11g (to extend network for xbox)=> Ethernet => Xbox 360
This is why I am confused.
The "g" AirPort Express does not have a setting to "Extend a wireless network". It does not exist. This is only found on the "n" version of the AirPort Express.
You may likely have been using a different type of setting with your old Extreme called WDS before you made the "switch" which will allow a "g" Express to extend and provide an Ethernet signal.
But, WDS is a nightmare on a new AirPort Extreme. The version of AirPort Utility that is provided with Lion 10.7.3 does not even allow this type of configuration.
