Any updates? Recently upgraded to gigablast from 300. Got a Netgear CM1000. Speeds capped right around 300 with a few above near 400 and a few low around 150. Tech came out, saw his meter check the line at 1.1 Gbps. Went and got the MB8600 thinking it was a firmware issue on the Netgear. Same issue. Right around 300. Checked connected to router and modem direct. No change. Using Surface Pro 4 with docking station that has gigabit port. I had more stable internet at 300 and a DOCSIS 3.0 modem.
I wonder if you pay for Cox Customer Care which is $10.00 a month that they've been pushing if your internet bandwidth will miraculously go up. Seems to fix Cox email problems.
I do have the same issued, Cox never fix my problem, i'm been with cox almost ten years, this year is very bad services? they're send the technicians to my home, the guy just replace slitter and he left he's say it's good to go. I told him you has to look inside my modem MB8600 see error, but he keep say it should be good now, but after he left the issue are the same? Then called motorola, they're swap my modem and are the same issue? also most my friends with cox has the same issued?
