Nstreme 2 Dual speeds

Nutcracker · July 20, 2007, 9:14am

I have recently installed 2 Nstreme 2 Dual links for one of our clients that are going to be pushing a lot of VOIP traffic through it. Before I started utilizing the link I did a bandwidth test and was shocked when I only got 15Mbps tx and rx. As far as I can gather from other posts, it seems that it might be the routerboards that just can’t go any faster. here is my current setup:

RB532A---->31DBI grid X 2----->wireless----->31DBI X 2---->RB532A

I am using CM9 radio cards, and the signal strength is between -54 and -58 on both links.

The other thing that I picked up is that I can’t set the radio’s to turbo mode

Could this be the reason for the less than usual throughput?

Hello.
Mmmm, but I zink if u put your antennas in Turbo Mode, I’m not sure of being an usual application of NStreme, because one antenna is Tx and the other is Rx.

Regards.

I have actually found that with the older versions of RouterOS (2.9.38), you can’t set the radio’s to Turbo. I am busy upgrading the RouterOS now to 2.9.44

Hope this fixes it

make sure that links does not interfere with each other. and then enable Nstream 2

or you have 2 nstream 2 links?

I have 2 X Nstreme 2 links between different buildings

The frequencies are 300mhz apart and the grids are also far apart(+/-1meter each)

Nope still nothing. I can set it to Turbo mode.

and my bad… frequencies are 200mhz apart

you can see in the print screen what my options are.

Are you sure about that?
I have a 2.9.38 Nstreme2 link and it works fine on turbo mode.

The problem is Brazil, change the country.

Best regards

I’ll change the country to something else tonight. I can’t make changes tonight currently as the are a constant stream of calls going through there. I’ll change it tonight. The only reason we set it to Brazil is because the choice of requencies are much more.
