Re: Gig speed not possible with purchased cable modem!!

Was this ever fixed? I'm dealing with almost the exact same issue. I'm not concerned with upstream as I know comcast doesn't have docsis 3.1. However, I too am only getting about half gig speed. Only time I got 940 was when tech used his device to test. Tech actually had to ask me why the upstream light didn't turn blue
