Hi David, thank you for your reply. 

I am using Maxis Fibre here in Malaysia, which is vlan tagged and using TM Unifi infra. 

As I do not have a fixed ip address, it keeps changing, but the ipv4 address is consistent with both routers as they start with 14.192 which is maxis's ip range. 

The issue isn't with the netflix account, because when the account gets flagged for VPN usage with the deco, it works again if i turn off wifi and use mobile data. So it isn't an account wide ban, just to do with something with the deco that makes netflix think i am an exit node or that i use vpns

I do not share the account with anyone else not in my household

I have not used the built in vpn client or server features on the deco before. 

My issue is very similar to the linked thread i referenced to 

Thank you.

Hi again, I have tried all of the solutions stated by maxis and netflix. 

Nothing works besides changing the router to something not deco or tp link for now.
