Mesh system with existing non-wifi router?

[dhph]

My home topology looks like the following:

ARRIS SURFboard SB8200 cable modem ->

SonicWall TZ400 non-wifi firewall router ->

Netgear GS728TPv2 Switch ->

3 Netgear WAC720 Wireless Access Points

I'm not happy with the performance or reliability of the 3 WAPs, so I would like to replace them with a single mesh system, but I do not want to get rid of my existing non-wifi router. Is this possible?

Yes you can put the MR in place of the SonicWall TZ400 non-wifi firewall router and use the MR as your main host router. Or you can leave the SonicWall router in place and use the MK system in AP mode.
