TM vs. Cable

I have to make the choice between TM home Internet and my cable provider. I'll give a brief history because I think it offers valuable context.

I've been with cable for years, just for the Internet. Suddenly they raised my bill 27%, to $80, for no discernible reason. And they wouldn't budge.

So at that point I tried TM, but didn't think it would work because of their weak LTE signal here. I opted for the middle plan, at $65, because of the better gateway and the $300 promo.

Sure enough, speeds were not good. I was getting 2 bars, but then I found one spot where I could get a solid 3 bars. Speeds now were about 30mbps. But then for kicks I tried patching my computer to the gateway via ethernet wire. BOOM! Speeds went to a reliable 320 ! (To my mind that indicts the gateways WiFi capabilities. BTW, my computer is in the same room as the gateway.) And I got those numbers even in a light rain the other day.

So I decided I would terminate cable. Now, of course, they suddenly found a promo that could apply to me. (The magic word to say at the phone prompt is "disconnect".) So I'm back at $63, with no contract.

So I have a decision to make.

The TM price is locked in ad perpetuity. The reception seems good even in inclement weather. I don't like the gateway, however. It allows very little configuration, virtually none via web access and the phone app is an absolute nuisance. I can't specify DNS provider and all the other things a normal router offers. I could hook up a router as an access point and do that, I think, but it's a hassle, and I don’t want two sets of WiFi radiation cooking me. Already, the TM gateway must be in the same room as me, for signal's sake, which I loathe. I also wonder if the current high speeds are a honeymoon they extend to new accounts.

Cable has a reputation for constancy, but we can get a lot of power outages here, due to trees coming down or wind, and cable goes down with them. Whereas I could put the TM gateway on a battery power supply and keep on internetting.

I also wonder if I could take the gateway on the road with me with a battery supply and have access that way.

So I'd appreciate perspectives on this, so I can make a good decision. At this point I'm favoring TM.
