MikroTik

Dear All,

Facing a strange problem on a 6 Km link.

Site 1:
MT= 411AH, Mini PCI= Compex WLM54AGP6A(26 dBm card), Antenna type: 5.8 GHz Solid Dish
Co-ordinates:
N= 30deg 19'21.40"
E= 78deg 02'13.31"
Elevation=661 m
Antenna Height=24m

Bridge Protocol=stp
dish.
Site 2:
MT= 411, Mini PCI = Compex WLM54AGP6B(23 dBm card), Antenna Type: 5.8 GHz Solid Dish

Co-ordinates:
N= 30deg 16'56.72"
E= 77deg 59'30.87"
Elevation=602 m
Antenna Height=24m
Bridge Protocol=stp
Site: Worked alot to get the signals equalize between -65/-62 dBm but failed, LOS is very clear.
The card rates are set to 18 dBm. Using LMR 400 pigtail(1 metr.) tried changing MT also.

1. when I increase the card rates, the performance drops.
2. there is not enough throughput.
3. Bandwidth test shows less than 2 Mbps both ways.
4. tried changing antenna feeds/pigtails also, no joys.
5. Worked on all frequencies (5300-5825) but did not work.
6. Worked with Bridge protocol disabled also.

How can I improve performance
I am not getting the enough bandwidth to run clients.

Please help

Hi,

I am new to this also but i think the receiving side, mode should be =station
You appear to have mode=bridge at both sides of the link ?

Its also running in wds mode.

Will doing a Ap-Client Configuration, or EoIP configuration really help?

Thanks!!

The client must be in station mode. I thnik this set up is much easier than the other issues that yoy have involving the TP-Link's, since in this application you Mikrotik in both ends.

There is a perfect example on the wiki that you can use as model for your setup.

and if you want to enable EoIP

Once again Thanks pilgrim for your replies on both the posts.

Well I have been working with MT now for about almost a year . I have also faced a lot of problems in the initial phases but then this kind of scenario is new and I am not able to rectify the cause.

I have read in many posts People attaining 50Mbps + bandwidth over distances of more than 30 Kms. I mean where am I lagging?
I am not even getting close to 4 Mbps levels....Its awful. How can I improve the performance.
Is the configuration I am doing correct or there needs to be some tricks involved.

What bothers me most is the difference in the signal levels on both sides.

I had read in one post that reducing the power output will solve the issue. so i had tried that too but didnt help.
Apart from it when I test bandwidth one ways(receive only) on both MTs, It starts with 17Mbps goes to 20-21 Mbps just for a second or two and then falls back to 4-5Mbps average(lowest levels even goes to some 500-600 Kbps) for some seconds.

While in bandwith test: THE TX/RX CCQ FALLS DRASTICALLY to 15-25% levels from 90-95% levels without Bandwidth test.

Is that a usual phenomenon when u put load on MT? Need your valuable advice.

Request to all!!

one card may be damaged, I see a -70 and a -56, something is wrong. I can't see Nstreme if is enable or not...must be enabled.
