What do you mean??check you mounting...
There's few thing you can do...no one can help me??
hi...Are you actually passing traffic over the link when you see those figures.
Try opening a mac-telnet session between the 2 units, (just so that some traffic is passing between them or use one of the units to ping the other)
Then check those reported rates again (whilst traffic is passing)
Report back on forum.
<Your overall system gain is excessive, that distance can be done with 20dbm +(20db antennas x 2) and still achieve better throughput.>

Change period size to 8 ms and you'll most likely double the throughput from the default 2ms.i changed the protocol to nv2 and the link is stable now but the throughput is only 4Mbps
can any one tell me does the 40mhz channel width really increases the throughput
as i am not noticing any difference
So you have to check all the components for problems. I would recommend to try to replace them one by one (lightning surge, pigtail, wifi card, antenna cable, antenna) and check whether there is a change. I suppose you are using full TX power settings on the wifi cardsno restarts are there and i don't know why the system is working like that(Low signal)
previously with TP-LINK 500mw radio the signal margin was 25db and now same with Mikrotik antenna alignment is not changed even a millimeter
what is the RX level after you lowered the TX power? If it is different from the calculated value you should solve the difference problem first (IMHO). The difference approx 5 dBm should be OK.yes i am using grounded cable
and also i have the tx power set to 19Dbm now but same result
does it mean the RX level is about -63dBm now (since the calculated value is approx -59dBm)?i am getting about 4Db less signal now
1) the Frequency usage or Scan doesn't guarantee that there is no signal on the same channel (these utilities show only 802.11 sources). Something better is spectral-scan (if you have 5.X ROS and the wifi card supports the feature)i checked every thing
like the pigtail the ALFA CARD (Tried it with R52 card) everything is ok
i have selected Ant A which is correct
and also the frequency i am using is absolutely free see the attached image
What Sir I Cant UnderstandCheck for interference from other Access Points.
I also Try It Change frequency change location tower change hight but sir nothing hight level issueFor both sites:
With and without Nstreme/NV2 and for Only-N and B/G/N
From Winbox->Interfaces go to your Wlan and in Wireless tab choose in Scan list->Default and press the Scan button. Check there if other AP have the same frequency or frequency near yours.
You can also press Snooper button.
Yes Sir LOS Is ClearThe LOS (Line of Sight) is clear?
When you have disconnections, it rains?
