How to connect AT&T Unite mifi device to my Time Capsule to extend my internet connection to all my devices.
I currently live where I don't have any hard wired internet connections. Therefore I can either use a satelite internet connection by Exede (super expensive and slow) or use my AT&T 4g/LTE plan and add a Mifi device. We tried the first option and it wasn't working. I have now purchased a AT&T Unite Mifi device which is in itself a wifi router. I'm trying to extend that internet connection using my Time Capsule or my Airport Express to all my other 10+ apple devices so they can all use the express or time capsule network to connect to the internet. The problem is I spent over 3 hours on the phone with AT&T and their tech support, and the Mifi device is not "Mac compatible." I find this hard to believe.
Anyhow, the device is supposedly able to connect via USB tether to computer, but I can't get my iMac to talk to it. Only option I see is connecting via wifi (which does work), however the range is limited and all my devices wouldn't be on the Apple ecosystem network so I can stream, use iphone remotes, or apple tv functions cohesively.
Is there any way to connect my iMac to my time capsule or express, via the ethernet cable/outlet, to share the internet connection that way, and use the express or time capsule to extend that internet connection out?
I've tried looking this up and tried it myself and keep getting snags. Please HELP!
