hello
i have a link with one repeater can transfer only 25 mbits from end to end while it transfers 50 mbits from end to repeater
A----------------B-------C
A to B = 35 km bandwidth test tcp both=50mbits tx / 45mbits rx
B to C = 15 km bandwidth test tcp both=50mbits tx / 50mbits rx
A to B = 50 km bandwidth test tcp both = 25mbits tx/rx
why it is devided by 2 ?
i m using 5ghz tubrbo with nstreme framer policy exact size
any body can help
regards
A to B = 50 km bandwidth test tcp both = 25mbits tx/rx
dont you mean
A to c = 50 km bandwidth test tcp both = 25mbits tx/rx
give us more info on hardware and power supplied to each connetion]
ifo on boards radios os version and do a
/system routerboard print
and give use that information also
oh , yeah
A to c = 50 km bandwidth test tcp both = 25mbits tx/rx

You need more spacing between the frequencies of the two links.
yeah i know , because i m using turbo mode , there should be 40 MHZ space
but this is not the problem
1)get all borad on the same version
2 how are you testing the bandwith
as you have this right
411(A)------------433(B)------------411(C)
so you testee this A-B and B-C 50mb
and thast doing tests from B right
try test like this
pc–411(A)-------------433(B)------------411(C)----pc
do bandwith test from pc to pc
then it will be true as if you test from the board you are using cpu power to create the traffic
try this and post the resolts
first i did the bandwidth test from A to B the result is 50 mb ,then i did the test from B to C it was 50 mb but rb411’s cpu was 100% because of the btest but the result was 50 mb , i did a test from pc -----A------B-----C-----pc the result was 25 mb
is there something wrong with my configuration ?because every link i make the bandwidth is divided by 2 from each repeater i make .
I repeat again:
How do you know that is not the problem?
Did you test it?
Also, you may need more cpu at B, like RB433AH.
You might be able to help that a little bit by using A and B as APs.
Running nstreme takes up a lot of CPU on the AP.
well , i telnet to B i found that i m consuming 60 to 90 percent of cpu load , maybe this is the problem .
so if its possable can you do a pc to pc test through your link
as i think this is your problem
so test it
pc------A-------B-------C-------pc
test it pc to pc and let us know
He already did. Scroll up.
I would double check to make sure this isn’t the problem.
guys i did the test from pc to pc it was 25 mbit i telnet to A,B,C cpu was 100%
i guess this is the problem
cpu usage
can mikrotik help us with this a 411 what type of throughput can we do before cpu usage?
