Recent Ethernet speed issues - RBR850
My wife and I both work from home and do several video calls per day, often at the same time. I previously had an RBR50 system (wifi 5) that I had used for years and had zero issues with for wired/et...
I see, that had reared it's ugly head again. Ya, there is a very LONG post thread over on DSLReports that was started many years ago about a Intel vulnerability with PUMA chip sets, one SB6190 was at the forefront of this discussion. There were other brands as well effected.
See if Spectrum supports any of the NETGEAR CM series of modems or maybe try a Motorola branded model. Not a fan of Arris or Hitron though I have one however it's only for phone services with the ISP.
What Firmware version is currently loaded?
What is the size of your home? Sq Ft?
What is the distance between the router 📡 and satellite(s)🛰️? 30 feet or more is recommended in between RBR 📡 and RBS 🛰️ to begin with depending upon building materials when wired or wirelessly connected.

Does this happen with the RBS turned OFF?
Does this happen with both wireless and wired devices?
What channel configurations are currently set on the router?
Try disabling the following and see:
Armor, Smart Parental Controls or Circle, IPv6 and Traffic Meter.
Has a factory reset and setup from scratch been performed since last FW update?
Thanks FURRYe38! Quick answers:
Firmware - currently on latest, 7.2.6.31 though tried the last 2 older firmwares for testing
House - 3500 sqft, 2 story, satellite is roughly 25-30 ft away. Again though, no wifi issues (in fact wifi 6 devices are actually faster than wired, both on main (front of house) and satellite (back of house, outside/backyard). Is your thought that the backhaul could be struggling and somehow taking bandwidth, or more likely processing power, away from ethernet on the router? I've toyed with wiring the backhaul but given how strong the wifi performance is it didn't seem worth it.
RBS off - just checked, no change
Wireless/Wired - Wifi is rock solid, only issues are with wired. Note that I could use wifi for video calls on my laptop or buy a wifi 6 adapter for my desktop but given this worked for years previously, I'm still convinced there is ethernet issues to be solved.
Armor, IPv6, Traffic meter - We do use Armor and I disabled that, same ethernet results. We don't currently have IPv6 of traffic meter enabled.
I have not yet done a full factory reset but will try tonight when work is over. I have some port forwarding stuff and static IPs which I assume would be better to setup manually than reload a cfg file?
Thanks again!
Yes.
OK, did a full reset, tested at default settings - It was a bit faster at ~450Mbs down 40Mbs up but still half of what I was getting previously.
Re-setup all previous settings (static IPs, port forwards, etc.) - same as above.
So small improvement but I see that same odd behavior of the speed spiking high in the first second or two of the test then tapering off down to the 200's-400's. Super frustrating. We'll see if video calls are better tomorrow. Sigh.
