Stupid problem with gDMSS lite

[gridflash]

Okay, i have a Dahua NVR5208-8P system that has been running very nicely for the past 2 years. A couple of months ago I upgraded the router to a TP link AX50 (very nice router).
Anyway, now my Android phone fails to connect to the NVR, actually the NVR says it's not connected to the router. And i'm unable to find anything in the manuals explaining how to reconnect.

Anybody have any ideas?

Are you using DHCP with the NVR? Is the router on the same subnet as the NVR? That's probably why.

Okay I found the DHCP switch .
That was what I needed.

Thanks
