Hi Geeks, 

Before i start, i am no expert in networking. I just bought few routers connected them and using them as independent routers. 

Current setup:

Router1: Archer AX1500 - ISP - doesn't support onemesh/easymesh (not sure of exact term)

Router2: Archer C6 v2 - connected to ISP router (LAN port to WAN port) - office room

Router3: Archer C6 v4 - connected to ISP router (LAN port to WAN port)- bedroom

Note: both archer C6 are connected to ISP via ethernet cable for maximum speed. 

My problem:

Since router1 doesnt support onemesh/easymesh whereas other 2 routers support it. 

I wanted to know if I can connect router2 and router3 in one mesh knowing they are not connected directly to each other as onnecting them using ethernet cable is also not possible.

Also, what should be the operation on router2 and router3 - wireless router or access point mode

Since i dont have not much technical knowledge it would be great if answers/suggestion a bit layman. 😅😅
