Solution1 : PoE Bridge Configuration
UBNT's multi-Ethernet radios and standard Power over Ethernet (PoE) injectors allow several interesting options to

consider when clustering several devices together. Here's a call-out to UBNT Forum member, @Dave-D for a Forum

post that inspired this Config - article.

Below are several pictorial examples of these options:
 Option A. - (Traditional) Two devices, two PoE's (requires a switch or router)
 Option B. - (PoE Pass-through) Two devices, one PoE
 Option B1. - (PoE Linking) Two independently powered devices, one PoE
 Option C. - (PoE Bridge) Two devices, two PoE's
 Option D. - (PoE Bridge and Pass-through) Three or Four devices, two PoE's

Option A. - (Traditional) Two devices, two PoE's (requires a switch or router)

Option B. - (PoE Pass-through) Two devices, one PoE

Note: This is possible only when a UBNT radio has a second Ethernet port to activate for this purpose. When

enabled, the device allows Power over Ethernet (PoE) power to pass from the main port to the secondary port,

thereby powering an additional device. From within the AirOS configuration console, select the |Advanced| tab

> Advanced Ethernet Settings > PoE Passthrough: [X] Enable.


Option B1. - (PoE Linking) Two independently powered devices, one PoE
Note: this is a similar configuration to (B.) above, however it introduces an added feature. If you power the first

radio through the "Secondary" port rather than the "Main" port, power is not lost to the next device if the first radio

is rebooted.

NOTE: For this configuration, do NOT enable PoE Passthrough as referenced in B. above. Use it with "PoE

Passthrough: [ ] Enable" UN-checked.

Option C. - (PoE Bridge) Two devices, two PoE's

Note: There is no switch or router required, or possible


Option D. - (PoE Bridge and Pass-through) Three or Four devices, two PoE's

Note: This is possible only when a UBNT radio has a second Ethernet port to activate for this purpose. When

enabled, the device allows Power over Ethernet (PoE) power to pass from the main port to the secondary port,

thereby powering an additional device. From within the AirOS configuration console, select the |Advanced| tab

> Advanced Ethernet Settings > PoE Passthrough: [X] Enable.


Solution2 : WISP Style Access Point (AP)
Create a simple, basic, ISP style Access Point (AP) to serve homes and businesses located across a wide area.

Because both the AP and customer equipment is UBNT, this system can serve up to 100 customer locations.

FIRST: Install a router as shown above. Configure it as a DHCP server with an IP pool that is large enough to serve

the number of customer devices (e.g. - computers, printers, etc.) you need to serve. NOTE: The pool should not

extend lower than 192.168.1.21. The instructions for doing this are different for each router manufacturer. Please

consult their FAQ for assistance if needed.

Configuring this Simple ISP-style Access Point System

Accessing the Radio:

1. Restore your radio to FACTORY DEFAULT values. This is critical, especially if you are troubleshooting a problem.

2. Connect the radio to your computer using an Ethernet cable. The Ethernet port is auto-sensing. You are not

required to use a cross-over cable.

3. Using a web browser, enter 192.168.1.20 as the "URL" to gain access to the radio's management console.
4. Enter "ubnt" as the administration account and "ubnt" as the password.

Configure the radio labeled as 192.168.1.2 (the Access Point) above:

A. Choose the |Wireless| tab and change only the following values:

 Wireless Mode: Access Point

 WDS: [X] Enable

 Press the [Change] button

B. Choose the |Network| tab and change only the following values:

 IP Address: 192.168.1.2

 Press the [Apply] button

--DONE-- with this radio (the AP), proceed to Customer Radios after repeating steps 1-4 above with them


Configure the radios labeled as 192.168.1.3 through .102 (the Customer Radios) above:

C. Choose the |Wireless| tab and change only the following values:

 Wireless Mode: Station

 WDS: [X] Enable


D. Choose the |Network| tab and change only the following values:

 IP Address: 192.168.1.3 (increment by x.x.x.+1 for each additional Customer Radio ... skipping

192.168.1.20)



 repeat the steps in this section for all Customer Radios

--DONE--

If using a Cable/DSL Modem:

E. Reboot or power cycle the Cable/DSL modem off and on before using this link.

--DONE--

Radio Installation errata:

 Install all outdoor radios using STP or FTP Category 5 or Category 6 cable

 If the Access Point will be co-located with high-power VHF transmitters, use Ubiquiti ToughCable Carrier cable

 Use UBNT's supplied Power over Ethernet (PoE) adapters and plug them into properly grounded AC outlets

Configuring Customer Computing Equipment:

 The router / DHCP server will serve configuration information to all connected computers. Configure computer

equipment for "Automatic" configuration.

NOTES:

1 - Secure your installation - modify the default administration account

 Select |System| tab > System Accounts

 Administrative Username [change it from 'ubnt']

 Hover over icon to the right, "Change Password" and change it

 Press [Change] button, press [Apply] button

2 - Secure your wireless network from unauthorized use by others

 Select |Wireless| Tab > Wireless Security

 Security > WEP (this is the ONLY encryption available in this mode)

 Preshared Key: [enter something long, but memorable to you]

 Press [Change] button. Press [Apply] button.


Alternate Customer Premises Equipment

SOHO WiFi Router

Rather than terminate in a single device or computer, you may wish to provide your customers with a SOHO WiFi
Router. Using a Ubiquiti device is advantageous because it allows you to manage the full network all the way into
the home or business. It also provides an additional layer of security because you can isolate a customer from your
wireless backhaul network very easily.

The isolation is a result of configuring your AP Router (the Gateway) to a different subnet (change from using
192.168.1.1 to use 192.168.2.1 instead) and then associating the SOHO routers WAN port on it, then having the

SOHO router serve IP addresses to LAN customer devices within the 192.168.0.x subnet. This configuration makes

the 192.168.1.x subnet invisible to customer devices!

The diagram to the right shows this variation graphically. The table below describes the simplest IP plan that will

work. Instructions below that describe how to configure a Ubiquiti SOHO Router as described.

Begin by configuring your AP Router (Gateway) interface to 192.168.2.1. Because each router is different, please

refer to your router manufacturers FAQ for assistance.

Solution8 : Bonding on Double AP-WDS/STA-WDS for Higher
Speeds & High Availability
Introduction

Bonding is a software mechanism in which you can aggregate multiple network interfaces to
achieve more throughputs with a higher level of availability. We will discuss a double link here
but keep in mind that more links can be bonded to achieve higher speeds with high availability
link.

Solution Diagram

Requirements

 4 UBNT Access Point A/B/G/N/airMAX depending on solution/application
 2 MikroTik Routers with 3 Gigabits Ethernet ports available such as RB750GL
 4 Antennas and proper cables (if use devices that don't have built in Antenna)
 True Layer 2 connectivity between both MikroTik devices on all links that will be used in
the bonding this can be two approaches
o by AP-WDS/STA-WDS on the UBNT devices
o by using EoIP within MikroTik RouterOS software

This Solution, we will select the AP-WDS/STA-WDS approach.


Configuration

 UBNT Devices
 MikroTik Router Devices

UBNT Devices
To Configuration and access of UBNT Devices is outlined in AirOS-Quick Setup Guide.

We will setting our configuration through the Web GUI.

A1

1. Under the wireless tab, set: "Access Point WDS" Mode
2. Under the network tab, set: Bridge Mode, IP address to 192.168.0.11, Subnet mask to
255.255.255.0 and Gateway to 192.168.0.10
3. Give the device a descriptive name and change the password

A2

1. Under the wireless tab, set: "Access Point WDS" Mode
255.255.255.0 and Gateway to 192.168.0.10

B1

1. Under the wireless tab, set: "Station WDS" Mode
255.255.255.0 and Gateway to 192.168.0.20

B2

1. Under the wireless tab, set: "Station WDS" Mode
255.255.255.0 and Gateway to 192.168.0.20


MikroTik Router Devices
To Connecting to your MikroTik router can be done with WebUI call “Webfig” or Winbox
and is well documented in their Wiki and Manual. This document will explain the command
line configuration, which can easily be followed with the MikroTik Winbox. And to avoid
confusion A1 goes to Ether1 and A2 goes to Ether2 and the same for the other tower
except replace the A with an B.

Router A
1. Log into your MikroTik router
2. Create a Bonding interface: Here you tell the router which interfaces should be included
in the bond. We are going to use round-robin mode, make ether1 and ether2 the slaves
and give the interface a name of "bonding1". The different modes are explained in
MikroTik’ S Wiki/Bonding.
o /interface bonding add slaves=ether1,ether2 name=bonding1 mode=balance-rr
3. Assign an IP to the bonding interface. Never assign ip's to the slave interfaces
themselves.
o /ip address add address 192.168.0.10/24 interface=bonding1
4. Add Link Monitoring so your router knows when a link is having a problem. We will use
ARP for link monitoring and tell the router to watch the ARP on 192.168.0.20. An
explanation of the different types of link monitoring can be found at MikroTik’ S
Wiki/Bonding.
o /interface bonding set bonding1 link-monitoring=arp arp-ip-targets=192.168.0.20

Router B

1. Log into your MikroTik router
2. Create a Bonding interface: Here you tell the router which interfaces should be included
in the bond. We are going to use round-robin mode, make ether1 and ether2 the slaves
and give the interface a name of "bonding1". The different modes are explained in
MikroTik’ S Wiki/Bonding.

o /interface bonding add slaves=ether1,ether2 name=bonding1 mode=balance-rr

3. Assign an IP to the bonding interface. Never assign ip's to the slave interfaces
themselves.

o /ip address add address 192.168.0.20/24 interface=bonding1

4. Add Link Monitoring so your router knows when a link is having a problem. We will use
ARP for link monitoring and tell the router to watch the ARP on 192.168.0.10. An
explanation of the different types of link monitoring can be found at MikroTik’ S
Wiki/Bonding.

o /interface bonding set bonding1 link-monitoring=arp arp-ip-targets=192.168.0.10


Bandwidth Speed Testing

We need to test and make sure the bonding is working. Follow these steps to insure
everything is working properly.

1. Log into Router A
2. Run ping to Router B

o /ping 192.168.0.20

3. Run the speed test tool to Router B

o /tool bandwidth-test 192.168.0.20 direction=receive
status: running
duration: 9s
rx-current: 213.4Mbps
rx-10-second-average: 69.4Mbps
rx-total-average: 69.4Mbps
lost-packets: 0
random-data: no
direction: receive
rx-size: 1500

4. While the speed test is running disconnect one of your ether's connected to your UBNT
Device, you should get a few missed pings then see something similar to the following.

status: running
duration: 8s
rx-current: 93.3Mbps
rx-10-second-average: 38.1Mbps
rx-total-average: 38.1Mbps
lost-packets: 0
random-data: no
direction: receive
rx-size: 1500

Conclusion

A couple of things I would like to point out here. The total bandwidth achievable here is 2X the
speed of the slowest link. Example: Let’s say one link does 213.4 mbit and the other does
93.3 mbit your total throughput should be around 180 mbit (90 x 2). The bonding
configuration outlined here is a half-duplex link. Bonding will work over multi-hop links as long
as there is layer 2 connectivity between the endpoints doing the bonding.

Sequence of Second 21 and Second 22 repeats

This LED sequence is displayed when the radio senses (correctly or incorrectly) that its [Reset] button is depressed

as the radio powers ON.

Several factors may simulate this condition
 Some UBNT PoE injectors include a [Reset] button. When it is depressed, it placed +Voltage on an Ethernet

cable data line. Ethernet cable that has been pinched may short a +Voltage to a data line, simulating the

pressing of the [Reset] button on a PoE injector.

 Additionally, improper Ethernet connecter termination (RJ-45) can short PoE +Voltage to a data line,

simulating the pressing of the [Reset] button on a PoE injector.

 It is possible that a PoE itself may be faulty, placing +Voltage on a data line even when its [Reset] button is

not being pressed (or even if you are using a PoE that lacks a [Reset] button!).

 It is possible that the Ubiquiti radio itself may have a "stuck" [Reset] button.
 It is possible that the Ubiquiti radio's firmware is corrupt (and is user fixable).

In almost all cases, the "flashing LED's" state is likely an error that is being simulated, rather than a true radio

failure.


Basic Troubleshooting guide

 Simple reboot. Power the radio off. Pause 20 seconds. Power the radio on. If that fails to clear the condition,

continue to next strategy.

 Ethernet cable fault. Replace all patch cables used by your installation (between the Radio and the device

connected to the PoE's LAN port). Re-terminate any already-mounted Ethernet cables. Replace even the

already-mounted Ethernet cables.

 PoE fault. Replace the Power over Ethernet (PoE) injector.

 LAN Ethernet fault. Plug the radio PoE's LAN port into a different computer, switch port (or an entirely

different switch).

 Stuck [Reset] button on radio. Using a stiff wire (such as a paper clip), gently "bounce" on the radio's [Reset]

button. You know it is "free" when you can feel a slight click when depressing it.

Advanced Troubleshooting

The alternating flashing LED sequence indicates the radio has entered TFTP mode (and can enter this mode due to

any of the factors mentioned above, but also if the radio's firmware is corrupt). When in TFTP mode, the radio is

available to receive firmware just as if it was on the assembly line in the factory. It is possible that uploading a

fresh firmware image (referred to as "Firmware Recovery") will recover your radio!

Instructions for this "Firmware Recovery" are found here: http://wiki.ubnt.com/Firmware_Recovery

Final Troubleshooting

The "Firmware Recovery" procedure is considered to be the most technical form of recovering a Ubiquiti radio. If

that procedure fails to work, you may initiate a Return Merchandise Authorization (RMA) by visiting the UBNT

Product Support page (http://www.ubnt.com/support).
