RV320 set up advise needed

[MicroProcessor]

Hello all.

I am new to using Cisco devices and have some understanding of network. My goal is to create a public WIFI for my small business using RV320.

I currently have one ISP (and will add another ISP later). I have RV320, DLink DIR-882 wireless router, DLink DSL-520B Modem, and 3 TPLink CPE210s.  The current setup is 520D <- connected by WAN -> DIR882 <-connected by LAN port 1 to 3 -> CPE210s. People access WIFI via CPE210s (set up as Access Point). 520D is set bridged mode and PPPoE login is done at DIR882. DHCP server is turned on in DIR882. I want to add RV320 in the network as I want to make use of dual WAN / load balance function in RV320 when I have 2nd ISP in near future. Which network topology is right for me?

1) 520D <-> DIR882 <-> RV320 <-> CPE210s

2) 520D <-> RV320 <-> CPE210s

3) 520D <-> RV320 <-> DIR882 <-> CPE210s

I prefer DHCP service handled by RV320 and all clients access WIFI via CPE210s. 

Thank you.

Not sure how you depends on Dlink Wireless router. (if you want to retire since you have other AP which handles your wireless clients)

Suggest to have based on your inputs.

 520D <-> RV320 <-> CPE210s

RV320 can handle good features you looking.

once you have dual wan connection here is the setup guide.
