Go for Mesh. If you are looking for more than 500Mbps connection you might need to connect the units using LAN cables. I used this one for my parents house. https://www.amazon.in/TP-Link-Deco-M4-AC1200-System/dp/B07KJ2TDMR/

Yeah needs to be plugged in. You take LAN out of your main router and connect to one of the units (base unit). Then the second unit can connect wirelessly to the base or via LAN cables. Something like this 1. Router ----- Deco Base )))))))) 2nd Unit 2. Router ----- Deco Base ------ 2nd Unit \--- LAN connection )))) WiFi backhaul Remember when using WiFi backhaul, the max speed of the second unit will depend on the strength of Base unit's Wifi signal where the 2nd unit is placed. My set up is like the router is upstairs computer room. Base unit directly connected to router via LAN cable. The 2nd unit is kept near the stairwell which covers all the downstairs. The range of the units are way better than the BSNL supplied ones.

I had 3 of these. Solid product. Upgraded to BE25s WiFi 7 last month.

I use a mesh system. Used to have 3x TP link Deco M4s. Now upgraded to TP link Deco 25 WiFi 7. Be used to have multiple extenders which were plugged into the wall and basically worked as repeaters but it was finicky. Go for a mesh system

I have a single erro router in the middle of my house it supports mesh, I would like to have more coverage in the yard, quite like the tplink mesh units like. https://www.pbtech.co.nz/product/NETTPL9402/TP-Link-Deco-M4-AC1200-Dual-Band-WiFi-5-Whole-Home?qr=web-share

I have a tp link deco mesh network, initially it was 3 nodes. I’m up to think 6 nodes now across probably 10k square feet over 2 levels. For the most part, it’s been perfect.

It’s been in about a year, I think it’s ac1200.

I had a TP-Link Mesh system (Deco M4), not possible. Maybe on their routers.
