How do I change secondary DNS on Fibre Modem FXA5000?
 

I was able to change the primary DNS from Local Network > Show Advanced > DHCP Settings > DNS Server.

There is only one field which is the Primary DNS. How do I add a secondary DNS? The reason I want to add secondary is because if my primary go down, secondary dns can be used. I tried adding using comma or space, but that is not accepted. The modem is not even smart enough to use itself as secondary dns by default.

Initially when I made the change, it used IPV6 as a primary dns on my phone. When I disabled IPV6, it now uses only the custom DNS that I set. No secondary DNS. So how do I go about setting secondary DNS? Any ideas?
