Hi I add iperf3 profile to ZRouter and check network performance. This is result. WZR-HP-G300NH AR9132 [ 4] 0.00-10.04 sec 118 MBytes 98.2 Mbits/sec 0 sender [ 4] 0.00-10.04 sec 118 MBytes 98.2 Mbits/sec receiver WZR-HP-AG300H AR7161 [ 4] 0.00-10.03 sec 222 MBytes 186 Mbits/sec 0 sender [ 4] 0.00-10.03 sec 222 MBytes 186 Mbits/sec receiver I seem AR9132 is slower than AR7161 Also you can tcp tuning on sysctl.
