Speeds way lower than I pay for

Please note that you are discussing throughput (bytes/sec) not speed (distance/time).    Regardless, we can't advise you much unless you describe the test scenario in detail.   Is there some actually-useful application that is performing inadequately or are you a wicked fiend for benchmarking like me?   :).    Consider to downgrade your service intentionally to the point at which one of your crucial use-cases/apps degrades unnacceptably.   Then bump the tier up one level from that.

I pay for 1 gig internet speeds and when I do speed tests, I get speeds way lower than that -- often in the 100-150 mbps download. This is ridiculous, I am paying for the fastest and getting the lowest. I tried to speak with someone online and they just kept sayin my modem doesn't support 1 gig speeds. Which is false, because I bought a modem and router that support speeds higher than 1 gig. Even if the modem doesn't support 1 gig, I should be at least getting speeds in the 600s I would think! Please help me get this corrected. Thanks

What are you getting for the upload speed ?

I have the same issue. Just signed up for gig speeds at a new residence. Purchased the Motorola MB8611 modem with 2.5Gbps WAN port and a Motorola AC2600 Gigibit router. After activating and testing speeds, and having a Comcast technician test them (he was very cool, nice guy) the best we could get over Gigabit ethernet connection was just over 600Mbps. I am paying for twice that. Any advice on what I should do?
