Bandwidth test in 3.27

RouterOS General
1

Hi,

I have a RB411 and a RB411A. If I run a UDP based bandwidth test between them, it works fine…

> /tool bandwidth-test 192.168.42.91 protocol=udp direction=both
 status: running
 duration: 10s
 tx-current: 11.9Mbps
 tx-10-second-average: 11.1Mbps
 tx-total-average: 11.1Mbps
 rx-current: 11.9Mbps
 rx-10-second-average: 11.3Mbps
 rx-total-average: 11.3Mbps
 lost-packets: 190
 random-data: no
 direction: both
 tx-size: 1500
 rx-size: 1500

but when I do it with TCP…

> /tool bandwidth-test 192.168.42.91 protocol=tcp direction=both  
 status: disconnected
 duration: 1s
 tx-current: 0bps
 tx-10-second-average: 0bps
 tx-total-average: 0bps
 rx-current: 0bps
 rx-10-second-average: 0bps
 rx-total-average: 0bps
 random-data: no
 direction: both

The same goes for Winbox - UDP works fine, but TCP just connects and then disconnects immediately.

Any ideas?

11.1Mbps it’s not fine…30-70mbps it’s fine

Given that they’re connected by a wireless link, 11.1Mps is fine, thank you!

I was talking about wireless too…you did not tell us your setup so no answers for you

SET tcp connections to only 1 to start with…

And limit the local tx value. You are on wireless. If you set direction to “both” on the router that you will also test the process can’t handle it and you get wierd or no results. Just the default settings on “both” directions (tcp) never worked for me…

Try to set low local tx and rx limit first…

If I was asking about link speed, you may have a point, however I was not and so the link method, the antenna used or the colour of my underwear are wholly irrelevant and therefore not mentioned.

Yes, did that - same result.

Again, tried that, but the problem appears to occur during setup and this makes no difference.

Hmm. Interesting. I’ll try the same from an x86 box and also a faster RB and see what happens.

Thanks for your suggestions.
