Need new a modem and router or combo.

My modem and router are from 2006 or 7. It’s probably time to replace as with the newest mac system update I am now having issues. Internet in this small apartment is hardwired in 1984 to comcast so not exactly a plus and we can’t use anything other than that (eg no dish) or we can use AT&T phone line (so 3mbps - um no thanks. I had that in the long distant past and adding the cost of a landline will make that expensive). I also don’t need speed as I have to buy the slowest they offer anyway due to cost - but longevity for the future matters so I don’t have to buy a new one for a while. I also don’t need something for a big place as I live in 2 rooms, 525sf.

Anyone have suggestions for something compatible with comcast that won’t break the bank? I had originally bought a separate modem and router incase one broke so I didn’t have to replace both. While the lights no longer work on the router, it at least still works. The modem still works. As a result I am not married to the idea to have a separate router and modem unless that is now more of a problem than what I have (fortunately) experienced.

Thanks in advance.
