Nighthawk m1 as my only wifi

Hello, we live in an area that has little wifi access. Our only option is hughes.net. or........i have am old grandfathered unlimited plan with at&t. I'm thinking about buying a nighthawk m1 hotspot, our only problem, is we live in an old two story brick house, with interior and exterior brick walls. Can someone help me come up with a solution to carry wifi throughout our house? We have several smart t
V.s, computers, phones, etc. And a college student that is learning from home and using zoom meetings, etc. Help?
