I currently have a 802.11s mesh setup successfully between a ath79 gl.inet slate and a tp-link archerc7v2 using current OpenWRT snapshots. The connection is fairly slow, but probably the best that can be achieved given that hardware.
Since 802.11 6E hardware isn't available yet, I'm thinking it might make sense to just use more recently released currently available hardware to see if I can improve connection speeds.
Have any of you used the DL-WRX36 in a mesh environment? Would two of those be a good idea? I see some recommendations for using the RT3200 too from several years ago too.
