XT9 ethernet lan connections seems to be isolated from each other (but reachable through wifi)

[pinpoint]

Have a nvidia shield connected directly to the router as well as a synology NAS. The shield is unable to connect to the NAS while both connected with ethernet, however if I change from ethernet to wifi on the shield, I manage to connect. I have read some users experience the same issue but no solution to this.

I have tried other devices as well and narrowed the problem down to the router.

Anyone know what to do?

Access Point Isolated is unchecked/Off?

[pinpoint]

Yes.

Another thing I just realized you can check, are the IPs assigned by DHCP server or manual?

[pinpoint]

It is assigned by DHCP (though the NAS gets its ip by DHCP, the ip is bound to a fixed ip)
