I've currently running 3 m5 mesh routers (most recent firmware.)

Based on my monitoring with a couple different apps, there seems to be a lot of interference, apparently due to proliferation of neighborhood wifi.

For most of my devices (~40), this wouldn't matter much but I've got 8 wifi cameras that keep dropping connection.

I can usually monitor one camera at a time w/o issue but when I bring up multiple cameras, the connections become unstable and drop.

I've considered just adding a couple more m5 routers but I don't think that's going to help overcome to the interference.

Range extenders don't help, may actually contribute to the problem.

House is about 2k sq foot 2 story. 4 of the cameras are outside the house.

I'm considering replacing the m5 mesh with an AXE5400 Tri-Band WiFi 6E Router (Archer AXE75).

I'm wondering if this would this help with interference issues and/or improve connectivity to the cameras?

The furthest camera from the router location would be outside, about 50ft away, with multiple walls between it the router.

Any suggestions greatly appreciated!
