Need internet provider recommendations

Hello! Me and my roommate are looking to switch internet providers. We currently have spectrum, but the service has been pretty consistently terrible. We have been using them for over a year and it has been lackluster the whole time. We have constant outages and even upgrades that have seemingly fried our hardware, our internet works in our unit maybe 60% of the time. There have been entire WEEKS that go by where we cannot connect to the internet, and we still have to pay in full for the whole month. We are hoping to get something comparable that actually works consistently so it doesn’t feel like we are pissing our money away. We don’t have many items that actually take up bandwidth (no PCs, no gaming consoles, we are hardly even home during the day to stream). The caveat is that we live in a basement, and we can’t drill holes in our wall or anything for more serious installations. We are considering switching to T Mobile maybe, but we were just wondering if anyone in the area has any internet provider they really like, specifically that is still consistent even in a basement? Thanks so much in advance for any help given!
