I cannot find in the "ADVANCED" menu a setting to disable all iPv6 protocols. Is there a method for doing this on the RBR750 models?
- SeaRefractorApprentice
Never mind, you have to click the dropdown menu all the way to the right on the iPv6 and select "DISABLED". That actually had already been done. Any additional suggestions?

What kind of drop outs are you having?
At the RBR or RBS?
Any front LED indications being seen?
Wireless and wired devices effected?
Is IPv6 actually disabled on the RBR?
Using ISP DNS or custom DNS?
What brand and model# is the ISP modem/ONT the router is connected too?
Which ISP are you connected with?
Has a factory reset been performed since last FW update or a power cycle?
How was the FW updated on the system? Automatic or manually?

It's a slow draw down in performance, then it appears that the RBS or RBR do a reboot. Logs don't help, because they are constantly filled with DHCP, a ridiculous amount of DHCP despite the lease times I've setup.
Either at the RBR and sometimes the RBS, I see the telltale flashing white (indicating a reboot) and the eventual blue when paired again.
After the issue, performance is back up to expected to slowly draw down again.
Double-checked, iPv6 is "disabled".
I used Cloudflare DNS as it tests faster than my ISPs DNS and I can get filtering with it, even though that duplicates the NetGear Armor role.
I removed the ISP modem and received my PPPoE password and the VLAN Tagging to use, so I'm connected directly to the ADTRAN ONT Model 424 (data sheet here:

I'm considering a factory reset, but I do power cycle each upgrade.
The firmware was performed "manually". I've yet to receive an upgrade automatically, even when I have that set, so I disabled that and watch for upgrades on the NetGear support site. The order, following the manual instructions is to upgrade the RBS units first, RBR last. I then power them all down, start the RBR first until it's fully on line and then start all the RBS units.
I have cycled the ONT, that doesn't seem to make any difference, the ONT seems pretty solid otherwise.
Wired has less problems, so it seems like it's primarily the wireless side. Was solid for months and months before I upgraded to the 7.2.8.5 (skipped the prior 7.2.8.2).

What brand modem did you have before?
And issue goes away when downgrading to prior version of FW?
Wondering if you used ISP DNS if something would change.
Wondering if there maybe something being mishandled between the ONT and RBR with this version of FW. Happen to have a spare router on hand? Something to try would be to put the spare router in between the ONT and RBR, DMZ on the spare router for the RBR in router mode.
Also would be good to know if AP mode has this same issue as well.
Would be good to get in a full on factory reset.
My 960 series is on v.5 FW and hasn't seen any issues since. I haven't had time to test my 850 or 750 series yet.
