Archer C6 AC1200 Wireless MU-MIMO Gigabit Router V3

Run ethernet to as many points as possible and install wifi 5 routers at each point. I use archer c6. You will get 500-600 Mbps speeds, but you will save a lot. If you have > 20-25 devices per router and want the most speeds then go for wifi 6e. Don't go for wifi 7 routers as they haven't yet implemented the full spec properly as of date. For wifi 6+, I would recommend Ubiquiti or deco.

If a router only supports 2.4 ghz you will definitely get bad speeds. Due to low bandwidth and network congestion. If you only need one additional router on that floor go ahead with what you have in mind. But I would try to future proof by buying routers which mesh with each other. It will help you scale in the future when you try to add additional routers to reduce deadzones and also improve access point roaming. Buy routers which supports mesh preferably with ethernet backhaul (can also do wireless backhaul with direct line of sight or less interference). Easymesh is the open industry standard but few routers support it fully. Onemesh or decomesh of tplink or Ubiquiti mesh works very well but you kind of get vendor locked. Choose your poison.

archer c6/a6, it's my main router and I can't complain, it just works

It depends on where you live since the routers could be unavailable for me it was the archer c6 since it’s the only one I could find if you can find and afford the BE9300 that’s the best one on the vd router list

You will need to increase your budget, because at this range i don't think you can support 100 Mbps at the same time as 7 devices. The best I can recommend is the tp link archer c6 , you can get it for 5k used if you look around.

This is what I went with a year ago. Powerful enough to cover my 1000 sq ft long rectangle of an apartment, even though I put it in the farthest corner away from other side. I've had zero issues with it. https://a.co/d/g2O6p69

I expect to use it for the next 5 years without issue.

I use TP-Link EasyMesh without any issues. C6 v4, AX23 and AX53 in one mesh network. The AX53 is the master (also works as DHCP server), others are nodes. Works pretty well.

Currently using TP link Archer c6 as a extender for my transworld connection. You can get mesh wifi from transworld aswell but that cost arounds 12k
