I have Netgear DOCSIS 3 Gateway, it has 4 gig ports and I have gig card on my PC as well ... still not getting there and I don't think that I ever will. From what I've read the 150/20 is not exactly that but I'll see what they can do. Still, 93 Mbps is not that bad.
reply to drquincy Make sure your modem can do more than 4 streams. I had a Sb6120 while doc 3.0 it could only do 4 streams and I could get about 120mbps. Replaced it with SB6141 and can hit close to 195 in the dead of the night. Of course I cant be 100% sure that is your problem.
