There is no magic router with amazing range. All routers have their power output limited by law and any good router is already at that limit. The RT2600AC is a good router and a   $300+ gaming BS router is not going to improve range. Even if there was a router with more power output than the law allows it would not help, your clients would still be too weak to respond.

As you have found out extenders do not help. You need either ideally access points or a good tri-band mesh system. Access points are cheap and perform better than mesh but require an Ethernet or MoCA connection back to the main router. 

you should go for TP-Link Archer AX10: Best budget router. https://get-vidmateapk.com/

I looked at Synology as they make many fine networks products. Their current router lineup is only two routers and both are AC routers. No AX routers. If you look at the technical reviews of other manufactures of routers that offer both AC and AX, you will note that as a group, AX routers out perform their AC counterpart even when using AC devices. 

I think an AX router is best if you want or need max distance using a single router.

Extenders, repeaters, True Mesh, routers with Mesh features, APs all have their good and bad points. Of course, the best is good old CAT 6 Ethernet connections.
