Cannot Reliably Connect Devices Home Internet

I live in Chicago, and having to restart my modem daily. This is a test to try to replace comcast, when it's up and running it's fantastic but when it disconnects it takes time to reprogram all the devices to the modem. I think it would be more profitable to work out most of the bugs before rolling out in a major city. Have no issues with my 4g phone which is also t-mobile, maybe run on that platform instead of crawling and stumbling on 5g???
