Better performance of link

Hi !

RB 433 (WMIA-123AG/E) ap-bridge ↔ RB 411U (WMIA-123AG(R)) station-wds

Is there any chance to achieve better results than 10Mbits/8Mbits (tcp, both directions) speed on bandwidth tests ?
enabled polling, nstreme (best fit), csma

Thanks for help!

Yes, you can double your throughput by making sure the signal strengths at both ends are strong enough so the radios run in the 48 to 54Mbps radio speed ranges and the CCQ is close to 100%.

Hi

Ok. I have everything in my room.
Signal strength is -35dBm, TX Signal Strength -33dBm, Signal to noise 72dB CCQ Tx/Rx 100%
And the bandwidth test (tcp, both) Tx jumping from 10Mbits to 16Mbits Rx 19Mbits to 24Mbits.

Sometimes Tx stop for a while, should I worry about this ?
Can I do something with this jumpin TX speeds ?

Thanks for help

too much power.
try to raise antenna gain to have a -60 signal.
how far are antennas, which version of routeros ?

It sounds like you are running your speed tests on the RouterBoards that are also running your radios. It is common knowledge that your speed tests will not be accurate as the RouterBoard CPUs will get saturated to 100% load during a speed test.

To get an accurate result, you need to run the speed test between equipment plugged into the RouterBoards.
