Docsis 3.1 SB8200- getting 300mbps speed only. Have gigablast plan
I currently have a gigablast plan and I am only getting 300mbps on all speed test. I have rebooted the modem and switch and swapped out the coax cable from the cable to the wall and the LAN cables as...
What model router and switch do you have? Have you tested direct to the modem with ethernet? Your signal levels are great and you have 2 downstream OFDM channels so congestion should be less of a issue.
You have to power cycle the modem each time you change what it is plugged into(PC or router). If connecting to the modem is fast but through the router is limited to 300Mbps, the first thing I would do is check QoS and NAT acceleration. Looks like the router itself bottlenecks around 791Mbps as per here.
I sure appreciate what you and Darkatt do here. I remember a conversation long ago with a Cox rep on the phone. I was frustrated already because the previous person rebooted my modem remotely, even after I asked them not to, which took down the phone, so I had to get back in queue. The person said to connect directly to the modem and see if everything worked better. Nobody had mentioned power cycling before, so I didn't think the direct connection worked, plus it meant I'd lose the phone again. I vented a bit. I learned the details later, but not from Cox. Always felt a little bad once I learned the right way to do it.
