I think you are talking NSTREME dual tab on the wireless table. That is for full duplex which some love and some hate.
If you go into the individual wireless card interface there is a Nstreme tab to enable and disable that on that one card. >From MT Nstreme pdf: The nstreme protocol is MikroTik proprietary wireless protocol created to improve point-to-point and point-to-multipoint wireless links. Nstreme2 or Dual works with a pair of wireless cards (Atheros AR5211 and AR5212 MAC chips only) - one for transmitting data and one for receiving. Benefits of nstreme protocol: * Client polling * Very low protocol overhead per frame allowing super-high data rates * No protocol limits on link distance * No protocol speed degradation for long link distances * dynamic protocol adjustment depending on traffic type and resource usage Hope that helps Steve Barnes Manager PCS-WIN RC-WiFi Wireless Internet Service -----Original Message----- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Robert West Sent: Wednesday, April 28, 2010 12:11 PM To: 'WISPA General List' Subject: Re: [WISPA] MT PtP With one radio. So if using one radio, do you add a second antenna to the setup to give you full duplex or how are you setting it all up? I've only seen it running with dual cards so I'm kinda interested in the single card setup.

I wouldn't use anything less than XR5 or R5H because their receive sensitivity is so much better. Plus you will use MMCX connectors with these two cards which is going to save you a lot of headaches over u.fl. Also definitely turn on N-stream. I had a link that was bouncing around between 75-90% ccq and couldn't ever get it up higher than that. As soon as I turned on N-stream my ccq went to 100/100%. And modulation locks itself at 54/54 all day long. Kurt Fankhauser WAVELINC P.O.
