Periodic reminder: if you haven't changed your internet plan in a few years, then you can probably increase the speed and pay the same money, or get a discount for the service you already have.
In my specific case today, the WOW 1 Gbps plan is down to $65 with a 1-year contract, and I'm currently paying $70 for 500 Mbps with a 2-year contract. The contract is up in June, and I didn't feel like arguing I should be allowed to slide from one to the other, especially as I'd need to buy a new Docsys 3.1 modem to get those speeds anyhow. I can just set a reminder for later.
(I was initially calling to set up the "new" 2019 modem with them so I could get the full 500 Mbps I was paying for, instead of ~260 Mbps the old modem was capable of. Download speed clearly not an urgent issue; the upload speed of 50 Mbps I've been able to get all along was more important to me. I had tried setting up the 2019 modem myself, but it turns out you need to call them on the phone to activate it. I found that out a couple of months ago during a service call.)
