Consider adding an outdoor access point such as EAP610.

if you can protect it from most weather, use another extender.

thanks for the reply. actually, what i did was to get 2 more RE550 units and attach them to my other existing RE550 mesh unit. i know its not the best solution because of the degraded download speeds, but the main thing i wanted is to extend wifi calling into my outbuildins. And it worked GREAT, i can now send and recieve texts inside my barn, carriage barn and shop. texts also.

starlink download speed is degraded like i thought it would. its 150-200 in the house, and about 20-40 in the barn. but who cares...i can get calls now. major happy and setup was a breeze.
