Buy the following -
- 3x TP-Link Archer C60 v3 (2k each on sale at fk) ~ 6k.
- 1x TP-Link Archer AX23 (3.6k on sale at amzn) ~ 3.6k
Flash openwrt on all these routers and convert them to a mesh network.
Use AX23 as a portal node (connected to internet) and C60 as access points.
You can install tailscale on AX23 to remotely access it even in case of cgnat which airtel uses in residential connections.
Total cost ~ 10k.
PS - You can create build scripts for openwrt firmware with your wifi/internet configs, so if one of the nodes die, you can flash the image to a new one and it will be up and running in no time.
