RBR and Sats Disconnect Monthly
RBR 850 and 3 RBS850 V4.6.9.11_2.3.5 Century Link ISP, 1G up and down RBR and sats disconnect monthly, can almost set my watch by it. This has been an issue going back to 2020 and FW: V3.2.16....

The only way to get everything back up is to unplug all (ISP, RBR, RBS) then plug back in. Any ideas?
Is it correct to assume that the RBR850 is in the (default) router mode? (not in Access Point mode)
Restarting only the RBR850 does not restore service? i.e the ISP router must be restarted as well?
Is IPv6 enabled on the RBR850?
The question about address reservations is interesting. I cannot find anything in the Zyxel C3000Z user manual that specifies the length of the DHCP lease that it assigned to attached devices (i.e. the RBR850):
(The default DHCP lease my RBR50 router assigns to devices is 86,400 seconds (1 day).
The length of the IPv4 lease assigned by the Zyxel to the RBR850 should appear in the router Advanced Tab, in the Internet Box in the Blue Box "Connection Status". For example, Spectrum assigns my RBR50 a DHCP lease of 86,400 seconds (1 Day, 0 hours, 0 minutes) I have verified that (as expected) my router attempts to renew the DHCP lease when 50% of the time remains, i.e. at 12 hours, and that Spectrum consistently renews the DHCP lease as expected.
I also learned that Spectrum assigns an IPv6 lease to my router of 1 week. i.e., 604,800 seconds. and the router renews this lease when 50% of the lease time remains. I know of no way for the user to display the IPv6 lease time. I discovered it by snooping on the connection between modem and router.
Late reply, apologies.
Was running great for over a month using just the router. Plugged in the first of three satellites two weeks ago to test and started having issues today. Answers below in order:
- Yes, default router mode.
- Have never tried restarting only the RBR, have always restarted both. With that, have always had wired connection to ISP device despite no connectivity from the router. Was previously the first thing I would check/ troubleshoot before restarting all.
- Yes, IPV6 is enabled at ISP and router level.

Perhaps it would be useful to describe the "issues" in more detail.
- The router says, "no internet"?
- Devices lose connection to the router?
- Devices remain connected to router but claim, "no internet"?
Meanwhile, the ISP router continues on?
I see that new firmware was released for the 850 product on 12/1, V4.6.14.3. Has the system been updated to that version?
Clarity would be helpful indeed!
Issues are spotty/ choppy internet (wired and wirelessly) then no internet at all. ISP goes to router, router goes to unmanaged switch, switch goes to all wired devices. Tested wired connectivity at RBR when having these issues and have similar access - spotty then no access.
ISP (wired) access works without issue - there is no WiFi from ISP (disabled) and RBR is in ISPs DMZ. I did this years ago to eliminate a double NAT when first setting all up.
Running V4.6.9.11_2.3.5 currently and this connectivity issue has persisted since firmware versions got into the 4's. There was a point in time where this was not an issue at all.

What is it the Brits say, "Bugger All!" (Guess I should look that up to make sure I'm offending - nah.)
Not much to lose then by updating to the latest firmware.
