OK. You have shown your ISP is delivering on its part to your modem. You have shown at least one Ethernet cable is good and that your computer can receive what you are buying.
When you did the firmware default reset, did you configure your router from scratch or did you import a previous saved configuration file? If you imported a previous configuration file, you most likely brought back the problems. You will need to perform the firmware default reset again and configure your router from scratch.
Here are some general configuration recommendations for dealing with Ethernet throughput issues.
Dynamic QOS should be disabled? Under Quality of Service.
Traffic Meter should be disabled? Under Advanced -> Advanced Setup -> Traffic Meter
Access Control should be disabled? Under Advanced -> Security -> Access Control
Is IPv6 enabled? If your ISP supports it, it should be enabled. Under Advanced -> Advanced Setup -> IPv6
If you add Wi-Fi to the mix,
Smart Connect should be disabled? Under Advanced -> Setup -> Wireless Setup
Is the 2.4 GHz channel selection on Auto? Try manual channels 1, 6, 11.
Is the 5 GHz channel selection on Auto? Try channel 48.
I went to Advanced settings - > Administration - > Backup settings - > then it says "Revert to factory default settings" with a button "Erase". Thats how I've been resetting it to factory settings
I can't find where it would show Dynamic QoS, just the upstream and downstream. I dont see a Quality of Service tab just a "setup QoS"
Traffic meter is Disabled
Access Control is Disabled
I have a IPv6 option. It says "Internet connection type" then has a dropdown with the following options. Disabled, auto detect, 6to4 tunnel, pass through, fixed, DHCP, PPPoE, auto config, 6rd Tunnel
I don't see an option for Smart Connect
2.4 GHz is on channel Auto
5.0 GHz is on channel 153
I do not have an R6400v2 and sometimes the configuration menus differ a little bit as do some of the features.
There is also a manual reset. A recessed button on the back of the router. With the router powered on, press and hold the button with a toothpick or pen until the LEDs start to flash. Wait a few seconds, release the button and let the router boot.
If you have successfully reset the router, it will start off with the configuration wanting to change your user interface password and asking security questions. Also the Wi-Fi SSID's and password will match the label on the back of the router.
What ever flavor of QoS you have, it should be disabled. On the IPv6, choose auto config.
I've also factory reset the router using the tiny button on the back with a paper clip and that worked too.
I selected IPv6 Auto Config and now I get multiple things to change (Pictures below)
A moderator has to approve pictures you insert. If you attach them, they do not have to be approved. You can only attach one photo per message. Just add a second message.
Did those work? I sent 2 images
No. See attached.
I see now, my bad. Just attached them now.
Leave all options in automatic.
I just reset my router back to factory and set the IPv6 to Auto Config and I'm getting 400+ on ethernet perfectly fine.
Thank you for taking time to help me, I appreciate it.
I'll keep testing my router throughout the week and see if it ends up going back to that 170-200 range again or not. Thanks again.
