I currently use a TP link TL-1043ND as main router with WI-FI disabled. This thing works fine with Openwrt 19.07.4 and SQM. It provides a solid 100/100Mbit/s which is more than enough for me. although it's starting to show it's age I am not planning to replace it soon.
I recently upgraded my in-house cables to Cat6 F/UTP cables with corresponding shielded connectors. Now it's time to upgrade my Wi-Fi. I tried the Xiaomi Mi4a gigabit router as AP but the OpenWrt enabled TP-Link Tl- 1043nd gave me much better ping, almost 0 bufferbloat and a great stable connection on 2.4Ghz. It however was painfully slow with Wi-Fi 4 (n) 1x1 35Mbit/s download speed on my laptop. I would love to go future proof so therefore this question:
Are there any LAN backed mesh AP's with Mu-Mimo minimum 2x2 wireless AC with full OpenWrt support (including vlan)? I am looking for 2 units with a total price under $300. Playing with a mesh package is not a problem for me. Omnidirectional 5Dbi antenna's are max since I want to create overlapping bubbles.
