How do I keep traffic separate on Vlan and Lan?

We have 9 Nest Wifi IP cameras on the network. They are on VLAN 102 with a subnet range of 192.168.2.x.

The Lan is on subnet range 192.168.1.x.

The wifi network seems slow when the cameras are on.

We would like to make sure the two subnets are totally separated so that the lan wifi does not suffer.

What is the BEST way to do this?

Thanks!

The best and the only 100% solution is to use separate physical infrastructure … both ethernet cables and (if needed) WiFi access points using uncorrelated channels. I guess that using common router should be fine if IP cameras have to be accessible from internet (or the rest of LAN), but be sure that router’s CPU is capable enough to handle all tasks “with ease”.

If that’s not possible, you can try to implement some QoS mechanism on the shared part of network. This might not be as effective as the first solution.
