Netgear Nighthawk Pro MR6500

Hi,

I have Nighthawk MR6500 ATT that I purchased a year ago. I live in a rural area and wireless internet is my only option, even then I’m on the fringe area and between an LTE tower and 5G tower, both 6 miles away. That being said, the service did work pretty well until about a month ago. Then it started freezing on videos and dropping the internet completely. Working with ATT Tech is a nightmare, I finally gave up and cancelled the service, though reading on these threads maybe my M6 was to blame. At any route, I now have no internet service and use my iPhone or connect my iPad to use iPhone data as hotspot. I would like to use the M-6 as a router only for my printer, and tv and 2 iPads for a Wi-Fi network.  How would I set that up? Any help is sure appreciated.  Thank you!
