Yeah, that's gold.
I feel like I should reiterate that a bandwidth check alone tells you nothing about your connection quality for online gaming, though.
Call support and get a tech to come over and check it out. I had to do this every once in a while when I was in Huntington because my damn street was wired in such a way that the internet connection seriously degraded after adverse weather and there was nothing I could do without having that fixed every once in a while.
In the meantime, check the wiring in your house to the extent that you can. Make sure you aren't using any more signal splitters than you have to, and temporarily remove your router from the connection and wire your PC directly to your modem. Do a bandwidth check and test that against the numbers that you paid to get. (If you don't know what upstream/downstream bandwidth you paid for, call and find out.) Ping test against a few different sites and make sure that the latency is consistent. Check your modem's status page (often
http://192.168.100.1 if I'm not mistaken) and make sure the numbers there are in order. I'm fuzzy on what the acceptable ranges are for most of those values but "downstream power level" should be as close to 0 dB as possible. Between -5 and +5 dB is ideal and -10 to +10 is the very edge of what is acceptable.
