RB433 ROS3.15 data throughput / bandwith on ethernet very slow
need a little help from community,
have a good working wireless link about 4000m, both side RB433 / transparently bridge ( bridge/wds-station mode 5ghz turbo)
Bridgeports: ether1, wlan1, wlan2 and wds1 ( on one side) / IP Adress 192.168.0.xxx/24 sign to bridge1
no firewall, no route, no filters, only a simple bridge between two pc´s
internal BTserver Test: 30mb/s in both mode ( send/receive) = that seams good = OK
but the problem is on ethernet-port
Bandwith Test with Iperf on connected pc´s ( 2x giga nic ) show´s only between 6000-8000 kb/s througput !
What do I wrong ?
Thanks for help and ideas - and sorry for my bad english,…
