I have a pair of CF-E313ac's which are 5GHz devices with 12dBi antennas designed for PtP/PtMP. I am on OpenWrt master and I have them running with 802.11s mesh, which is all working nicely except that I would like to see speeds closer to the ethernet interface maximum of 100Mbps, right now I only get about half that.
I have them plugged in to a 120Mbps LTE router (confirmed getting that speed when plugged directly in) but my throughput across the two E313s using speedtest.net is only around 50Mbps down.
iwinfo shows the link wifi speed as about 650Mbps, so what is happening?
I am using wpa3 encryption on the mesh wireless, could that be the speed goblin?
What are some general tips and best practices to optimise this kind of setup for speed?
