Spped looks fine but that is just a test.
Dslreports is a good place to post and find info for intrernet connection. I found a few posts and two people mentioned a piece of plastic left over on the coax was causing their problem so you may want to check the coax out for a good connection and check for any plastic that sill may be on the connector.
What is the modem you are using and is that all you are going through to reach internet, ie no router??? Another posted updating their modem do DOCSIS 2.0 fixed problem. As the newer modem was getting better signal strength. Really shouldn't need to do that though but depends.
Have you already tried unplugging the modem and plugging it back in or resetting if that doesn't work.
