Hello,
i now replaced the rb951-2n with a new hap lite.
I make wireless connection between RB951G-2HND to HAP LITE using NSTREME , but i have not high throughput…
I did iperf test between pc connected to hap lite and pc connected to the other routerboard and i get the following results..
iperf-3.0.11-win64>iperf3 -c 192.168.1.1

Cpu usage of routerboards during iperf 40-50%
i was expecting more than this…
The configuration are
On the HAP lite

Distance: 9-10 meters
Established link:
The RX rate sometimes is dropping to 13mbps and after some secs grow up again the RX rate to 270-300mbps…
I tried also to put down the tx power in both routerboard, but the throughput is not changing…
The wlan is in bridge with other ether ports on both routerboard, fastpath is enabled in wlan, bridge and ports and in the queue list i set wlan to only-hardware-queue (i read in some post this to enable fastpath)
I’m using an advanced channels to do some tests to get the max badwidth i can reach without interferencies so the signal is clean..
