Hi All !

Please help me to decide. 

Currently I have an ER605 + a Simple old D-link wifi router. 

I'd like to change the Wifi router since I'd like to have multiple SSID -s spanning through VLANs and the current one cannot do these....etc

Which way would you go ? 

Change the ER605 to ER706W and kind of combine the two functions. 

Keep the ER605 (which serves the purpose currently) and change only the Wifi router to an EAP655 ? 

Since Wifi feature and HW capability wise the ER706W and the EAP655 seems to be similar for me the logical way would be to combine and change to the ER706W since it's the same price like the EAP655 but then I can sell my ER605 2nd hand so would save some money and decrease complexity. 

The main feature I'm using on the ER605 is wireguard Client and S2S VPN to an other ER605, DDNS, DHCP, Firewall, DPI...  Which all can be done by the ER706W as well (correct me if I'm wrong)

Pros and Cons please.
