Slow speeds if IPv6 turned on Orbi RBK353
I have a RBR 350 with V4.4.1.29_3.10.80 firmware in router mode. I have changed internet provider from Virgin to the local Fibre to the Home company. With the ISP supplied Nokia Modem / Router I g...
Thanks for your reply. This is not a double NAT problem.
My ISP provides a choice of using their Router a Nokia G-2426G-A or if using own router they provide a Nokia G-010G-R modem to which I connected a Orbi RBR350.
Using their router the full speed around 900 is obtained with IPv6 and IPv4.
Using their modem and the Orbi with IPv4 only enabled full speed around 900 is obtained.
Using their modem and the Orbi with IPv4 and IPv6 enabled the speed drops to 300-400.
These speed are measured by Ethernet.
The ISP provided Router is a Nokia
My ISP has recommended keeping the Orbi with IPv6 turned off as the best solution.
There are several other threads on this subject so assume this is common to other netgear routers.

https://www.netgear.com/about/contact-us/IPv6 is a dumpster fire with Orbi on this firmware. So many problems...I too have it turned off, the network is unusable with it turned on - starting anywhere from 2-6 hours later. Router gets totally confused. I have sent in debug logs, tried all kinds of tests, starting with thebeta. But NG doesn't seem to be addressing it.
