hello..

many people says that wireless(wifi) point to point link is always a half duplex one...but here in mikrotik forum people says dual nstream will provide u full duplex link...
is it true that dual n stream will provide full duplex link if yes how?

Yes. One card for Rx and one for Tx.

exactly with dual nstreme you can have full duplex because 1 wireless card it only function like RX and the other card like TX, so you need a routerboard with 2 wireless card in each site.

Heri.

is nstream is relaible and stable soultion i mean i hav heard abt that dual nstream fails twice-thrice evry day...is dualnstream is not a good performer...i really need a good uptime.i dont want any downtime ina point to point link.

dual nstreme is a performer, But it is not without it's faults. The concept, and implementation is fairly simply. However, my nstreme2 setup has problems, and I have been working with support to try and figure it out.

First off, nothing in the price range of a dual nstreme setup compares. I have a pair of 333s with r52s and 29dbi solid dishes with radome covers. Our link is true 30Mbit, full duplex, and ping times are AMAZING. I have found nothing in M otorola line that can produce these results with their crazy prices.

However, my nstreme2 setup goes blind sometimes, and I have no idea why. When it does, the watchdog catches it, reboots, and 15 seconds later it is back in operation. This happens two to three times/day. So, we are down 45-60 seconds per day. Annoying, but I can live with with the tradeoff for performance. I notice this mostly when pps hit the ceiling at night.

here are some of my posts regarding nstreme 2 for more information
