Nstreme ptp help

RouterOS Wireless Networking
1

hi all,

I am trying to create a dual nstreme link with a throughput of nearly 70mbs tcp one way. I could get the link working but never with a throughput of greater than 25mps tcp. After this i decided to create a simple WDS bridge to test if i could achieve a greater throughput. On this WDS link i can still only get 25mbs tcp one way, also when enabling Nstreme, polling and disabling CMSA the link fails. Even if these are enabled individually the link fails.

I am using 2 x RB333 and r52 cards and as you can see below the ccq is 100%.

I have the outputs for each ap below. Does anyone have any suggestions?

Thanks in advance!

PtP - is it possible?

I don’t believe you can use WDS with Nstreme.

3

Thanks JP, you were correct that you cannot enable nstreme and disable cmsa in WDS mode. This is now enabled using bridge on one AP and station the the other but i am still unable to get the desired throughput.

Any other suggestions? would using a better card such as Ubiquiti SR5\XR5 help?

Thanks again in advance

4

What are your signal strengths on both sides?

5

the signal strengths were -40 to -50 both sides. It seems as if the turbo mode is broken lol

Am i right in thinking that to enable turbo mode all you do is select 5GHz-Turbo under the band?

6

I currently have no countyr code set. Would enabling allow the turbo mode?

7

Hi all again,

I am still having no luck with turbo mode. I have now setup an EoIP tunnel and using NetPerSec i can get 35.2Mbits/s. This is a test setup and the units are a few metres apart with TX Power set to 5db. The CCQ is 100% with data running through. Is there a setting to enable Turbo Mode?

Cheers

8

You have too much power. Turn down the power until you are at a healthy -60 to -64.

9

I have now tried varying the power output of the radio cards from “Card Rate” 1-5. The rates 1-3 do not assosciate and 5 has a signal strength of -51db and still the turbo mode still doesnt appear to kick in.

Any other suggestions?

What cards are people that can get turbo mode to work using?

10

would adaptive noise immunity help?

11

Try dropping to a normal channel size. Sometimes turbo hurts more than it helps.

Are you using compression?

12

No compression is being used. Would that help the speed?

I will try using a 20mhz channel but i really need to demonstrate that these speeds can be achieved.

I have 2 x RB333 Units using dipoles 5.8 and 2.4 Ghz located about 1-2 meters apart and i also have an external test link with 2 x 17dbi 5.8Ghz antennas located a very short distance apart. Do you think the 2 antennas should be moved even further apart and even with the card rate on 1 could this be too powerful?

Thanks

13

Compression should help -but- you can’t use encryption with compression. IMHO you really don’t need encryption if you are using N-stream.

Move the antennas apart so you aren’t any hotter than -64 and try a 20mhz channel.

Also, there is a new n-stream test package you should try.

14

Thanks for your jwcn. I will try your suggestions over Christmas. Have a merry Christmas!

15

Think i may be getting somewhere.

As you can see the signal strength is now lower (using dipoles) and still 100% CCQ when running traffic through the link (Bandwidth test) but still am only getting about 21Mbits/s TCP on the bandwidth test. I checked the CPU usage and it’s running at 100%. Could this be whay i cannot get anymore throughput on the link? Any suggestions on what to do to reduce CPU usage? the units were upgraded using the combined packages from the mikrotik website. As a test what speed can i over clock the RB333 without burning them out?

Thanks

You can turn connection tracking off in the firewall. Other than that yes, the CPU is the limitation.

17

Thanks again

Connection tracing is off. Will contact support

18

Ok. Not sure why you would contact support over a hardware limitation but ok. You need to buy beefier hardware for your application.

19

I have just re run the test using PC->RB333->RB333->Server as the pther test was using the internal bandwidth test and the CPU runs at 47%-83% and gives 35Mbit/s throughput. Back to square one lol.

20

Ok. Are you using Nstream?
