So we dropped Comcast about a year ago after ongoing frustrating issues including a BBB complaint that connected us directly with someone at corporate in the US and they still weren't able to resolve our issues. We switched to T-Mobile and for the first couple months it was great, but what you'll find (and I've since learned is very common) is that it just randomly drops sometimes. My partner works from home and this is a major issue when he's on a zoom call or a productive work flow. We put up with it but it was pretty frustrating and would sometimes cost him some money.

So, this is such an unsatisfying answer, but we recently re-signed up with Comcast and are now using both (someone on here also said they do this when I asked several months ago about these issues). T-Mobile is $50/month and Comcast is running a two year deal at $25/month, so hopefully with back up options, the $75/month for internet and less stress will be well worth it. When the T-Mobile isn't dropping we have great download speeds, so there is that!
