hap ac2 (main), hap ac(slave): 6.42.5
I use WDS mesh on both 2G and 5G. I found when my phone connects to slave AP, whatever 2G/5G, there are network throughput on both wlan interfaces. Although both wlan interface are in the same bridge, yet I don’t think throughput should pass each other.
And if I disable WDS on 2G interface and use WDS on 5G only, the performance is better.
