Low throughput

i installed a link for maximum of 5 kms
rb112 boards , 2.9.38 mik
wireles cards are EMP8602
band used 5 ghz

signal level is -48
abd bandwith test show maximum of 768 uplink and
4 mbps downlink , i expected really more
I Am using Ap bridge / station wds , will Ap bridge / Station ( cz all traffic will be ip ) ensure more bandwith and performance of the rb112 , is ip routing less hardware hungry then wds ?

Hi,

Your signal level is too high, try decrese power to get about -60 db.

well i putted in same location 2 patchs 23 db , and i discovered the problem
the grid antenas needs to change polarity
i fixed now , the 2 patchs together give -48 signal , throughput is 13 MBps
and from a side patch and other side a grid the signal is -61 but also the throughput is 12 mbps , i will make both sides Grids i beleive i will reach 17 Mbps

i am getting on tcp maximum throughput 9.1 mbps without nstreme
and 8 mbps with nstreme i tried all 5ghz channel , the best was on 5ghz-10 mhz , channel 5790 ,
could be the rb112 cannot pass more than this bandwith with wds ?

you will get much more if you use RB532 with Nstream on! RB112 is not made for Nstream!

Look at this test report, v3.0 has improved wireless driver that runs faster on low power boards such as RB112:

to Uldis!

You guys cheat!! You have enabled RSTP on V3.0!! Enable it on V2.9.38 and it will perform the same!

Here is some secret to all!! If you can not get enough speed out of nstream or nstream dual, just enable RSTP!!!
This has been tested!

I am sure Uldis can tel us why!!!

If you want to do a fair test, compare aples with aples!

Mr G

Ehhh… Are you sure you know what you are talking about? RSTP has nothing to do with throughput of routers, only failover and preventing network loops

Yep! Take 2 x 532 with 4 x CM9 cards, set it up for N-stream dual and check it out for you self! I also don’t now why RSTP increase performance! In theory I agree with you!

Check out the specs for that test as on that link placed by Uldis!

Compare routing to bridging on both software versions!

Regards

Mr G

it is nothing to do with the RSTP, we only had that package enabled - we didn’t use protocol-mode=rstp. Anyway, we will have rstp package integrated in the system package in one of the beta versions.
And you will not get the same speed with nstreme in v2.9 even if you enable the rstp package.

Uldis,

In theory this should mean that RB532 should perform even better with Beta5.. Do you have any tests showing this? I personally have done 40Mbit/s UDP / 26Mbit/s TCP 5G Turbo in real life environment (6km) on RB532A

jowi007!

I need to know more information about Alepo’s configuration? do you have

a mobile number? i’m from Lebanon … my phone number is: 03/709 273

really urgent!

thnk you
