Hi. I've got some troubles with my LHG 5 ac bridge. I cant establish speed more than 100/100 mbits (Bandwith test). Fresnel zone is 100% free. Distance 3 km. Signal strength about 60 dBm. Now i use 5860 MHz channel its most free channel for me. I use 802.11ac protocol. With nstream and nv2 bandwith less (something about 20/20 mbits) than with 802.11ac (dunno why). I think something wrong. I want establish 300/300 mbits goodput is it real? Whats max throughput for LHG 5 AC (Tools -> Bandwith test)? If something wrong, hat could be the reason? I think something wrong with hardware. Help me pls.

Thanx in advance.

P.S. In attachments my link calculation and supout files.

Do not consume resources by running the btest on the devices you want to test. You are not resting the throughput but ability to generate the traffic. And it is absolutely different discipline.

I understand. But if i use btest. Is's only 50% cpu usage. Tomorrow i will test my bridge with iperf and two notebooks, but i think it will be similar with btest)

btest uses only ONE core of the router. So if you have a CCR with 4 cores, it will use only 1 core, and the other three will be idle.

ALWAYS use iPerf, or better: real file transfer a traffic what the end user will use. For example: Database is in location 1, and user is in location 2. He (or she) started a download of the database (or upload). Simulate this traffic from both ends, that will give you a more "realistic" figure.

Thanx. I try to test my bridge with iperf or real traffic today.

Testing bridge with iperf gives similar results.

Give export of wireless settings and screenshot of registration table. AC performs horrible in noisy environments.
