Postal Code

I subscribe to Fubo and recently we lost access to our locals and RSN, I can see the arris G34 modem thinks my Postal Code should be:

{"postal":"06811"}

Which is Danbury, Connecticut. I am 170 Miles north of Danbury.

Fubo worked fine until last Friday, when my wife had to reboot to get the wifi back up, how did this Postal Code change and how do I change it to my Postal Code?

Thank you

David
