Hate to bug ya but up at our place in mountains and trying to use an airport express as a range extender but keep getting orange flashing dot..is there an easy way to use that as a range extender..thx!!!

First I assume you have an airport extreme or other express in the home already. Now you’ll need to go to airport utility and choose to allow that network to be extended.

Next be sure your express is set to extend the network as seen below. Not creating a network as above.
