I’ve found that wifi connection on my board is too slow.
I’ve measured it with iperf: 11.6 Mbits/sec
At the same time, test from Andorid phone and Windows machine connected to the same network shows ~90Mbits/sec.
Can it be fixed?
BTW, my router is configured to a “Mixed n/ac” mode for 5G band. If I turn it to “ac only” mode, the board cannot attach to it.
