I am trying to get Nstreme Dual working on a pair of RB433GL’s.
The RB433GL’s work fine with a single radio each, but not with 2 radios each.
Does Nstreme Dual work on the RB433GL?
The RB433GL’s have firmware 2.38 and the router version is 5.9.
David.
The problem is the same as the upgrade path to the next version ?
Thank you for the reply.
Can you elaborate, are you saying I need to upgrade the version of Router OS I’m using?
David.
Yes, try for example, 5.9-> version 5.11 or 5.14
5.13-it seems to me a bad fuck
5.14-don’t know whether or not the error corrected
I use myself and successfully 5.11
What is your BIOS version? (/system routerboard pr)
I have upgraded one board to 5.14 with firmware 2.39 and it seems to be working OK.
Been trying the second board, but every time I enable a bridge to the ethernet port the system crashes. The only way to recover it is to hold the reset switch in whilst powering up the routerboard.
Have I damaged the routerboard in doing a firmware upgrade?
David.
I don’t know, but it looks like this in your theme. 5.14 Never upgraded, and I quickly turned 5.13 router died and was given a new, My position is such that someone with something that does not speak on-the-spot here. What is this error? OK I think let the developers deal with their faulty software. Soon, all routers in addition to which it is sent to mikrotik went bad soft Head Office
Very good developers and then continue in the same spirit! I personally do not dare put more from 5.13
use r52hN instead, if you are trying 802.11a-turbo in dual 
just experience
Thank you for the advice about the radio cards.
I have tried to find a different version of RouterOS on the Mikrotik web site, without success. I was going to downgrade the firmware to see if that cured the problem.
David.
I am now having problems on both my RB433GL cards with RouterOS 5.14.
Is there a problem with 5.14?
How do I downgrade?
David.
I have downgraded my RB433 to RouterOS 5.11 and firmware 2.38.
Now I’m back to the original problem that whenever I set up a bridge to ether1 the board crashes.
What am I doing wrong?
David.
Now things are working better, I’ve found a faulty radio card and two faulty RF cables.
Upgraded to RouterOS 5.14 with firmware 2.39 and it seems stable again.
When I’ve replaced the radio card I’ll try again.
David.
do you have skype or email address to communicate with you if there is a problem, you can look at the problem and eliminate
I can let you have an email address for me.

I have not got Nstreme Dual working, but I have bonded the two radio links.
Thank you,
David.
You have not said what you were trying to accomplish (specific performance goals?) with nstreme-dual, but as for bonding radio links, you may find that performance isn’t as good as you had hoped. As I understand it, the more consistent the connections being bonded, the better the results–and unfortunately, wireless connections tend to be a lot less consistent than wired.
What I am trying to achieve is the best radio throughput using MikroTik products for a back-haul link over 12km.
Testing the bonded link I am getting a unidirectional throughput of 120Mbits/s, I presume with bidirectional traffic the rate will be reduced by about 50%.
The bonded link uses 2 radio boards fitted into each end of the link, a 20MHz bandwidth and the frequency set at opposite ends of the 5GHz band.
David.
Others here have more experience than I with longer links, but I would think that you could get better performance with a single 802.11n link (dual-chain, 40MHz channel) and a couple dual-polarity antennas, or four single-pol antennas with decent separation.
(FWIW, I have toyed with the idea of setting up Nstreme Dual using two 802.11n links as above, for a theoretical 300Mbps bidirectional. I wonder if anyone has actually tried it, and what the results were?)
My current set up is a single radio card at each end, 40MHz channel, but I’m disappointed, unidirectional throughput is about 60Mbit/s.
Modulation is nstreme, must try other types.
David.
This is where people ask you to post an export of your wireless configuration ( / interface wireless export compact )
and the specs for your radios and antennas, what you are seeing for signal strength and noise floor, etc.
Is that 60Mbps UDP or TCP? Also, if the traffic is being generated by one of the MTs, rather than from & to devices on either side of the link, you may be measuring the CPU capacity of the device, rather than the capacity of the link.
Hi david54,
I would want to know if you have successfully achieve your dual nstreme link ?
I want to go on with a similar project ( 1 x RB433GL + 2xR52nM on each side) in dual nstreme and I try to find if someone did it successfully before.
Thanks
