RBR850 - SPC trial MISTAKENLY activated - Cannot set custom DNS servers?
Hardware reference: One Orbi RBR850 + two synced Orbi RBS850 satellites running Netgear firmware version 4.6.3.16_2.0.51. Windows 10 PC using Firefox v92.0.1 and Chrome v94.0.4606.61 browsers to acce...
Well you can try this,
See if you can get v3, even the last version loaded. See if it blows this away, factory reset and then try applying DNS.
Do this off line with the RBR from the ISP modem.
I would turn OFF the RBS and leave them alone during this process.
If it works, you can try re-updating back to v4. Leave the DNS setting in place.
So...
I have a POSITIVE DEVELOPMENT to report on this issue!!
Before diving deeper into any further firmware back dates and script implementations in the effort to enable telnet on my RBR850 device I tried ONE MORE factory reset and RBR device reconfig with the RBR device disconnected from the ISP/WAN.
And... SUCCESS!!
I was able to set custom DNS server address in the Advance/Internet Setup page. See the screen grab below. Again, IP addresses and DNS server addresses redacted for security.
And, I was able to successfully apply the DNS server settings to the RBR device and confirm through network device behavior that the network devices are using the custom DNS servers.
So, I am HOPEFUL that the custom DNS server settings will remain persistently saved to the RBR device and that an overnight firmware auto-update will not overwite or erase the custom DNS server settings from the RBR device.
Fingers crossed for a few more days that this works to finally solve the problem.
I will report rmore results in a few days.
Thanks again for all of the continuing forum support help on this issue!
Good to hear. I was hoping a reset with out the RBR connected to the Internet would result in something. Seems odd that something is preventing that from happening whilest connected to internet services. Must be something on NG side that maybe effecting that...
- Agree that something at the NG device registration serves prevent the DNS config.
I’m convinced that the NG device registration servers see the SPC trial activation on my RBR device and send SPC-specific config to my RBR device when it checks in.
So far, nearly 24 hours after recent reset and reconfig, the DNS servers are still persistent on my RBR device.
Fingers still crossed that this success is durable.Ya thats part of SPC, they user there own specific DNS, so if SPC gets enabled, custome DNS on the RBR gets grayed out.
A factory reset should clear that out however if the service is active between the RBR and NG, NG may re-enable it during the reset so whic is why when you disconnected the RBR from the ISP modem and reset and setup from scratch with out it connected to the ISP modem, the RBR wasn't effected by NGs SPC services checking on the state.
Ya you should be good. I would do a backup configuration to file for safe keeping. Saves time if a reset is needed.https://kb.netgear.com/000062080/How-do-I-back-up-the-configuration-settings-on-my-Orbi-WiFi-System
