I am trying to extend the range of my airport extreme using a 1st generation airport express. When I plug the Express in and open airport utility, the utility will not see the Express. This is contrary to all the help sources I have been consulting about extending wifi range which make it look so simple (14 year olds can do this on YouTube...). Is there a step I'm missing? Do the two devices need to be connected by ethernet for the initial setup, then separated? Is there a mismatch between the generations of the base station and the express? The base station is newer tho I'm not sure of its generation and naturally I can't find its documentation. I have plugged the Express into several locations hoping to get a connection but no dice. Any suggestions appreciated.
