I flush arp/neigh tables on all endpoints before each ping so both multicast and unicast is tested. Within the same quick-n-dirty OTA env I get the following UDP (iperf -P5): HT40 (ieee80211ac=0): qca6174 -> qca988x 228.383 mbps qca988x -> qca6174 238.528 mbps VHT40 (your config): qca6174 -> qca988x 234.64 mbps qca988x -> qca6174 298.723 mbps VHT80 (vht_oper_centr_freq_seg0_idx=44, vht_oper_chwidth=1) qca6174 -> qca988x 377.092 mbps qca988x -> qca6174 483.287 mbps Michał
