Something about the older boxes not being able to support faster speeds. When I moved into current house, I told them I wanted the same $30 50mb plan I had at our intermediate house. The said they no longer had a 50mb plan, the slowest they had was 100mb, but the box at this house didn’t support those speeds because it was older.
I argued with them back and forth for a while, threatened to just sign up with Cox instead, and they ultimately split the cost with me.
High speed internet is a freaking joke. Most people don’t need the speeds they Pay for, the profit margins are insane, and speeds are artificially throttled based on what you are willing to pay. I was on the phone with a rep once and they doubled my internet speed with a few taps of the keyboard.
