Hi Robert, welcome to the forum.
You've got a downstream sync rate of 3264 kbps, which is quite good for 55 dB attenuation. Is the connection stable at around this figure, or does the router resync at a much lower speed at times (e.g. at night)? You might have a low IP profile as a result of periodic low-speed resyncs, or you might have a stuck IP profile. Or you might be the victim of serious congestion or ISP profiling limiting your speeds.
You can check your IP profile at
