Make UBNT device use a single polarity.

by Jim Bouse 16. December 2013 11:36

FYI in /tmp/system.cfg (configuration file):

radio.1.txchainmask=[bit mask]
radio.1.rxchainmask=[bit mask]

Where bit mask means which chain/chains to enable:

1(0bit) - chain0

2(1bit) - chain1

4(2bit) - chain2

So you can make combinations like 1 and 4 = 5, means chain0 and chain2 enabled. And so on.

NOTE: Chains are HW specif, not all have all chains or the same chains.

I guess my sample will help to make live easier and avoid custom scripts to be installed.

AC1 to AC2 GPS Coordinate Pusher

by Jim Bouse 13. August 2013 16:37

Ok... Since it looks like UBNT isn't excited about pulling data from AC1 into AC2, I whipped up a python script that copies the GPS coordinates from AC1 to the device so that it can be used in AC2.

WARNING!!!: THIS MAY BREAK YOUR NETWORK.

Don't say I didn't warn you.

That said, I have run it against my network and it just caused breif outages while devices rebooted.

# 
# AC1 -> AC2 Coordinate Pusher 1.0
# Jim Bouse
# 8/13/2013
# jim@mobileitpro.com
#
# This script runs on Python 3.3.2 on Windows.
# I have not tested against any other OS or version
# This script may destroy your network.
# This script may destroy your network.
# This script may destroy your network.
# I really mean it.  If this script blows your network up, 
# I'm sorry but I did warn you.
# 
# The purpose of this script is to query AirControl v1 and populate
# the coordinates from AC1 into the config file in the devices.
# When the coordinates are in the config file, AirControl v2 properly
# places the device after discovery.
# 
# NOTE: <------ READ THIS !!!
# This script reboots the devices after the file change.
# This means you will lose connection and it will be a problem if you # do it during a busy time.
# GOOD NEWS is that it only does it on the devices that need it.
# BAD NEWS is that it will have to be run a few times to get all the
# devices in your org,
# because if it reboots an AP, the clients will not be able to be
# connected to until the next pass.
#
#
# Instructions: Place this script and plink into the same directory.
# Open a command prompt and CD to the directory.
# Run this file.

AirOS 5.5.2 for UniFi

by Jim Bouse 3. December 2012 13:41

From time to time, I install UniFi access points for customers.  These customers normally do not need a controller and just want a nice looking AP.  NVX from the UBNT forums put together the firmware needed to convert the UniFi to a standard UBNT radio.

Here is the original post: http://forum.ubnt.com/showpost.php?p=389380

I have mirrored the files here: AirOS 5.5.2 for UniFi.zip (10.65 mb)

Low Cost Outdoor UPS

by Jim Bouse 30. July 2012 16:24

I own a small WISP and need an UPS in a small enclosure at the bottom of my towers to provide temporary power for when the grid drops for a few minutes/hours.

This is often coupled with a multi-port POE injector from Wifi-Soft and a router for a WISP tower location.

This comes to $387 for an outdoor UPS with a run time of about 8 hours without power for 2 - 8 watt radios and a RouterBoard.

Here is a similar version of what I have described.

by Jim Bouse 28. March 2012 11:28

NOTICE! This resets it to default (factory).  If you want to just reboot, use "reboot".
