Maybe this is common knowledge for most people, but did you know that you have to be hard-wired (ethernet cabled) into your Internet in order to reach the advertised speeds? Wireless routers are only capable of a fraction of the speed you are paying for.
About a year ago I increased the Internet speed at the Airbnb. The TV in the living room was buffering, so I blamed it on the slow speed. I later learned I just needed a range extender; speed was not the issue. As so often happens with recurring expenses, it slipped my mind that I had upgraded the plan and was paying more.
I've been taking a look at all my recurring expenses when I stumbled on this one. I was paying for the fastest possible speed, but getting none of it because everything is wireless, so the speed was already capped. To sweeten the deal, I told the representative I was thinking about canceling so that I could get an even better rate than first quoted.
Bottom line: I reduced the monthly fee from $70 to $35, and all it took was a 10 minute phone call. That's a $35/mo savings!
