Hy everyone

I make a link of 17 km with rb 433 and rb 333 + ubiquiti xr5.
The data rate is 54/54 mbps and signal strength is -62 dbm, but when i run bandwidth test the data rates falls to 6/6 mbps, signal strength continues stable. what may be happening with this link?

Configuration:
point A rb 333 + xr5 + power supply 18v 3,6 A + 29 dbi dish antena
point A rb 433 + xr5 + power supply 18v 3,6 A + 29 dbi dish antena

i dont know what exactly the problem , but you can explain the detail wireless configuration of your exisiting PtP , what's type of abnd / frequency do you use, what version of RouterOS do you use , is it possible link PtP have Line of Sight / LoS or not? . If u want to increase tx/rx or greater upstream / downstream bandwidth maybe u can use dual antena + wireless minipci card in your routerboard with configured channel, nstream , data rates , tx power. Thanks

I'm using a rb 333 with routeros 4.6, minipci card ubiquit xr5 5.8 ghz (5825 mhz), disc antenna 29 dbi, with clean fresnel and 17Km of distance, power supply 18 V 3,6 A.
And at another point with rb 433 routeos 4.5. xr5 (5825Mhz), disc antenna 29 dbi, power supply 18 V 3,6 A.
The routerboard are bridged and tx power are default.
The signal strength is -62 dbm in both points tx/rx rates is 54/54 mbps, but i run bandwidth test the tx/rx rates falls to 6/6 mbps and the link's throughput is 1,5 Mbps. Has anyone had this problem?


PS: In rb 333 has two xr5, i think the problem ca be the power supply.

Any suggestions?

post your configuration. are you using nstreme?

what is your CCQ while attempting to pass traffic?

I'm using wds + bridge. the tx/rx CCQ is 90-100% but falls to 20% when has trafic.

I'm using single dishes antenna each side.

Do a uni-direction test in one direction then in the other.
Post the ccqs in from each test.
I would be inclined to think that one direction is impacted more than the other.
This would indicate that one antenna is too close to another antenna on a near frequency.

you did not mention if you're using nstreme...

I'm having this EXACT issue and I figured it out..
Go into advanced mode in wireless. Select the DATA Rates tab. Select "Configured" and Uncheck anything lower then 36Mbps.

The link will drop and come back at a good rate. Best I can tell the radio was dropping to a lower modulation rate to produce lower latency and killing the CCQ.
