Firmware 2.2.1.210 released as of 10/3/18

Here is how to diable AutoUpgrade:

To stop the Orbi from installing the updated firmware automatically follow the steps below.  

 

Perform these step after you downgraded the firmware to a prior release.

 

1) Launch your favorite web browser and go to <Router IP Address>/debug.htm

 

2) Login <username> <password> when prompted

 

3) Check Enable Telnet

 

4) Start a Telnet session.  I use Putty.  Enter the <Router IP Address> Telnet is using port 23

 

5) You can skip this step if you like.  I am calling it out for illustration purposes only...  

Type nvram show | grep auto_* <ENTER>

You will see a list similar to this:

root@RBR50:/# nvram show | grep auto_
vpn_access_mode=auto
wl_auto_antenna=1
set_auto_agreement=0
orbi_auto_upgrade=1
ipv6_autoConfig_dns_assign=0
ipv6_autoConfig_dns1=
ipv6_autoConfig_dns2=
upnp_enable_autoScan=0
ipv6_auto_dns_assign=0
bas_auto_conn_flag=0
orbi_auto_upg=0
autofw_port0=
ipv6_auto_dns1=
ipv6_auto_dns2=
qos_auto_bandwidth=0
green_enable_autorefresh_status=0
enable_dev_auto_refresh=1
wl_rate=auto
auto_check_for_upgrade=1
auto_update=1
root@RBR50:/# root@RBR50:/#

 

The 3 configurations highlighted above you will want to update the value from =1 to =0

orbi_auto_upgrade=1

auto_check_for_upgrade=1
auto_update=1

 

6) To update run the following commands:

nvram set orbi_auto_upgrade=0  <ENTER> (no spaces after set)

nvram set auto_check_for_upgrade=0 <ENTER> (no spaces after set)

nvram set auto_update=0 <ENTER> (no spaces after set)

 

7) Type the following commands to confirm the 3 configurations are set to =0

nvram show | grep orbi_auto_upgrade <ENTER>

nvram show | grep auto_check_for_upgrade <ENTER>

nvram show | grep auto_update <ENTER>

 

8) After you confirmed the 3 configuration values are set to =0 then type nvram commit <ENTER> (this step will save the changes)

 

9) Type exit to terminate the telnet session

 

10) Go back to the <Router IP Address>/debug.htm web page and uncheck Enable Telnet

 

Please note within a day or so the Orbi will know there is an updated firmware release available but it will not automatically install it.  If you do go back into a Telnet session after the Orbi knows there is an updated firmware release the configuration orbi_auto_upgrade will have a value greater than 1.  That is okay.  Do not change the value back to =0
