LEDE 11ac low throughput

  1. 3 months ago

    Board WPJ344LV/HV-A 6A08
    radio card WLE600VX 11ac
    firmware LEDE r 2292
    I've been working with the LEDE for a few months. It builds, loads and works fine, but:

    • I can't get the firmware to put the 11ac card into 80 MHz bandwidth
    • the rate algorithm stops at VHT MCS 7 (300Mbps), it never tries to go to MCS 8 or 9 (360/400 Mbps)
    • with radios linked at 40MHz bandwidth, I get 300Mbps link speed from both radios, and 200 Mbps throughput by iperf3. But, the radios' CPU usage is already at over 80% (sirq), so I would never get the 500+ Mbps throughput I can get using the Compex firmware.

    Has anyone else seen this?
