w60g bridge vs ap-bridge performance issues

Hi.

So I’ve noticed a substantial difference in setting a wap60 to bridge vs ap-bridge.

Currently this wap60 is a ptp link and I am in the process of converting it to ptmp. However my existing client keeps on flapping. I upgrading to the latest RC (on both sides) and noticed a huge difference.

mode=bridge

interface w60g station monitor wlan60-station-2
       connected: yes
          remote: 30:07:4D:84:A0:74
             mcs: 7
        phy-rate: 1925.0Mbps
          signal: 60
            rssi: -70
       tx-sector: 14
  tx-sector-info: left 19 degrees, down 19 degrees
       rx-sector: 96
        distance: 199.24m

mode=ap-bridge

interface w60g station monitor wlan60-station-2
       connected: yes
          remote: 30:07:4D:84:A0:74
             mcs: 2
        phy-rate: 770.0Mbps
          signal: 35
            rssi: -70
       tx-sector: 14
  tx-sector-info: left 19 degrees, down 19 degrees
       rx-sector: 96
        distance: 199.23m

PHY & MCS rate is MUCH lower by only changing the mode. Wondering if anyone else is seeing this?

Please downgrade to 6.43rc17, fixes for this will be available soon

Thanks. We noticed a lot of client flapping with rc19 and rc21. Reverting to rc17 stabilizes things.
Looking forward to distance measurements and RSSI in SNMP making a return.
