Orbi RBR20 Slow Upload Speed
I have an RBR20 (Firmware V2.3.5.26)with one satellite that works great for my mobile devices, With AT&T Gigabit, I reliably get speed tests in the Orbi app of 500-600 Mbps up and down. When I run th...
There is a router already built in to your ISP modem. This would be a double NAT condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktop
I would try option #3...
Thanks for the fast response. I should have mentioned that I've done all that.
The Arris router is in bridge mode and all WiFi on it is disabled.
As I mentioned in the original post, I've eliminated WiFi as the problem by wiring directly to the RBR20, but it still only gets 5Mbps max upload, even over a CAT6 cable.
Every other device works perfectly fine, including a Windows 10 laptop. It's only the tower PCs that get 5Mbps upload on the Orbi. They each have different wifi and ethernet cards and both work perfectly fine on other networks. They only have this problem on my Orbi.
What are the adapter models on these PCs and any differences between them and this one tower?
If other PCs are working and this one tower isn't, I would check and review this one tower PC.
