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 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 used to have a TP-Link AC1200 router. I’m not sure if it was because I was torrenting for a longer period or more torrents, but the router would throttle to 1 Mbps. I’m not sure why this happened, but when I rebooted the router, it would work fine again. This happened a lot, but it happened less often with the ASUS router.

I live in a 4600 square feet house. The modem aka the main router is downstairs and the download speed is 300 Mbps and upload speed is 100 Mbps. The router which is near my room upstairs gives me a speed of 30 Mbps the name of the router is tp link ac1200. What router do you recommend budget $300.
