All of these devices average around $200–300 for 3 or 4 devices. I really miss OpenWrt and would like to find out a solution that works to give me around the same performance as a tri-band mesh setup. I saw an interesting post that got me thinking. What if I purchased 6 dual-band routers, two-for each room. Would it be possible to use one as a dedicated wireless backhaul, connected to the second device in each room via ethernet. Then that way my WiFi devices connect to the the non-backhaul router. Would this setup still support things like fast roaming or something similar to automatically switch routers depending on what room I'm in?
I can find some descent AC1750 devices that support OpenWrt for around $50. It may be a little more expensive, but seems like it would be worth it if this works. I imagine that backhaul may be better since I could potentially use both bands simultaneously for the backhaul. The other concern is just managing this many devices, but I would think if they are all the same it should be pretty easy to automate. Does anyone have any experience using a configuration like this? I did find another tri-band device today made by ASUS for around $100 that I might try if this isn't feasible, but I'd really prefer to use OpenWrt.
