Sector Aentena Configuration & Upload

[nmthaker]

Hi,

I configure 18dbi sector aentena with RB433 AH & connecting CPE at diffirent location but i am not getting proper upload. Can any one suggest us the good configuraiton. We are using as base station where multiple clients is getting connected.

attached is screenshot of configuration.

To start some tests …

1. Set freq mode = manual tx power
2. Set country = your country
3. If it’s a single 18dBi pannel, set antenna mode A (or B), depending where your pigtail is connected at minpci card. The way it is, your card is transmitting at the 18dBi antenna and receiving at an empty connector. Use A port anyway.
4. Antenna gain: EIRP will be calculated according to your country rules, e.g. 18dBi antenna, XX dBm card power = some EIRP … and default power will be set lower if necessary. Left card power at default and antenna gain at 0 to start testing.

And later upgrade 4.14 to 5.4

Hi

Thanks for your prompt reaponce but as you said to upgrade does it remove existing configuration or what ???

I don’t think so. At some V 5.X release candidate there was an issue when the antenna port was “B” and after upgrade they boot up at antenna “A”. And commands on winbox does not change the antenna port, was necessary to do it using terminal / console.

But at 5.4 I guess no problem at all. It will keep the same config. Last week to perform a test on a RB411 I downgraded to 3.3 then started upgrading to 4.1, 4.17 then 5.2 and finally 5.4, and no problem at all.

Anyway, left ip > neighbour discovery interfaces = eth, at least. If you loose connection you can use ETH interface to gain access to the router via winbox & interface MAC. Easier than use serial console

Hi,

Thanks for the changes, i done the require changes attached screen of the same but the issue is same that i am not getting upload properly as if i set to any user and set upload 1Mbps same download 1Mbps i am getting only 256kbps upload where download i am getting proper.

Can you please advice how can i achieve 1:1 data transfer rates

I see -70dBm received signals from your clients by the AP. Enough signal to have 11Mbps/11Mbps.

You left antenna gain = 18dBi. Try to set it to 0 (zero).

After that if there is some ap power reduction to hit some irradiated power value, making antenna gain = 0 will drive the AP to transmit at default power.

Question: are your clients B mode only? If so, change the “band” from 2.4B/G to 2.4 only B.

Tests: after making antenna gain=0 change the data rates from default to configured. Mark only 5.5 & 11 Mbps at basic and suported speeds. This will force clients to connect at this speeds only. If for some compatibility reason clients does not connect, left datarates at configured but select 1, 2, 5.5, 11Mbps on suported and 1Mbps on basic (equivalent to default anyway).

Btw, take a look at the “status” tab to see the noise floor measurement (or select on registration pannel to see CCQ & signal to noise). Those figures can help.

Hi,


Thanks for your support but i don’t know but after making this changes the system is not stable, previously up to 5 KM 2mbps link was running very well but now it is giving very poor result, there are so many ping drops and internet is getting disconnected, RSSI is again -69 to -75 but result is not good as it was previously. Please suggest some great solution to make this proper

Well, restore the previous data-rate to default at first. And if your clients are only B mode capable, keep mode at 2.4G only B. Otherwise set it back to 2.4G B/G.

With this two changes you’ll have your original setup again.

Keep manual power & antenna gain = 0 dBi.

Then at clients registration table right click one of them => Show Columns => Distance (km). Check If there is an “odd” number for distance …

Tell what numbers you have.

Questions:

• which mini-pci card are you using at AP?
  
  \
• which hardware are you using at your clients?
