@RogersDave is there anyway for you to tell me if docs 3.1 is avail in my area ?
@lethalsniper, DOCSIS 3.1 is not enabled in your area yet. I also don't have a deployment schedule at this point.

For anyone who has a CODA-4582 with V2.0.10.19 loaded, running in Gateway mode and experiencing slow download rates or slow web page fills, try this: disconnect all but one ethernet connected pc from the modem and turn off the wifi, both 2.4 and 5 Ghz. Then restart the modem by pulling and reapplying power. Run a speedtest after that to see what your results are. This morning as I was filling the wifi SSID and passphrases with junk after a factory reset, I noticed that the refresh time for GRCs perfect passwords was very slow, until I turned off the 2.4 Ghz wifi, at which point the web site page refresh time noticeably dropped to what I would expect. So, just an observation, but there is definitely something odd going on when the 2.4 Ghz wifi is up and running. At the point that I was doing this, there was nothing connected via wifi and only one pc was connected via ethernet. I use GRCs perfect passwords to generate the SSIDs and passphrases, which requires a page refresh to generate new alphanumeric sequences: https://www.grc.com/passwords.htm
I usually run the 4582 in Bridge mode with an Asus RT-AC68U behind it and I haven't come across any issues so far, at least from what I can see. My modem was updated to V2.0.10.19 last night and after running a factory reset late this morning the speedtest results that I see appear normal. Highest I saw with the modem in Gateway mode and a single pc connected was 923/28, which for a late morning speedtest, is normal. If I run a speedtest prior to 8 am I'll see download speeds in the 940 range and upload speeds in the low 40s.
Head of Line blocking? We had a very similar problem with the CGN3 a couple of years ago. Any connection to a 100 Mb/s device would cause all of the modem's ethernet ports to run at 100 Mb/s from what I remember. The temporary solution was to run a gigabit switch between the modem and any 100 Mb/s devices until the firmware was changed. Have we run into the same situation again?
@JohnBeaudin run a speedtest after you have unplugged the device from the modem. If you still see low rates, restart the modem by pulling the power off of the modem and then power it back up again to force a restart. Run another speedtest after the modem is back up and runnng to see what change has occured. Running a speedtest before and after will confirm or deny the requirement to run a restart to temporarily fix this.
@Alex4161, results in gateway mode, 923/28 Mb/s (all wifi disabled), which for a late morning speedtest, is normal. Results in Bridge mode thru my RT-AC68U 747/24 Mb/s. That result thru the RT-AC68U is also pretty normal for this time of day. I have seen as high as 940 Mb/s down thru the router. For gigabit service, the 68U is underpowered. Time for a standalone router running something like Pfsense or Opensense.
Those results are with Firmware Version 2.0.10.19
As soon as I find an opportunity to kick the modem back into Gateway mode to experiment I'll let you know. Finding time to experiment during the Christmas holidays without starting a family mutiny is a little difficult, but as soon as I can, I'll give that a go. The slow page loading on a secondary browser tab was something that I didn't anticipate, and I haven't seen that before with previous modems or firmware versions. So, at this point its only an observation. Whether or not that translates to a lower data rate is a good question.
