Connect Airport Express to Motorola Surfboard Modem/Router
I have purchased a Motorola SURFboad eXtreme Wireless-N Cable Modem and Router (model SBG6580). In order to extend the network to all rooms of my condo, I purchased a 2nd generation Airport Express.
I was able to setup the Airport with my Mac using the Airport Utility and I was able to connect to the my network; got a solid green light on the aiport!
When I tried to access the network, using the Mac, in a room farthest from the Cable Modem but next to the Airport Express, I was not able to see my network. As I walked closer to the modem, the network became visible and I was able to connect.
I then tried to turn off all security on the network and got the Airport Express to connect to the network and and got the solid green light again. I tried the same experiment, and got the same result.
So wondering what I need to do to get the Airport Express to connect to the Wireless Modem and extend the network?
Any ideas and suggestions are appreciated!
Thanks in advance!
