Ubiquiti RocketM to Cisco Router

Cisco Router -> RocketM (AP-WDS Mode) this will setup a transparent bridge to allow the Cisco to do the DHCP.

Ubiquiti Point-to-Multipoint (PtMP)

Point-to-Multipoint (PtMP) links are used routinely to serve up to 100 locations from a single Access Point (thanks to Ubiquiti’s airMax technology).


There are many approaches to providing PtMP services.  This example is the simplest, using a single Ubiquiti radio with an omnidirectional antenna to create a bridged network.  Even a simple IP addressing schema is included!


Clearly, a more complex approach is often desired; one that uses multiple Ubiquiti radios with sector antennas along with a fully routed (rather than bridged) configuration. That however, is not this article.  Most new users will benefit by starting with this simplified approach to become familiar with PtMP or to serve a smaller, limited area.

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 The instructions for doing this are different for each router manufacturer. Please consult their FAQ for assistance if needed.


Configuration and Setup


Accessing the Radio:

  1. Restore your radio to FACTORY DEFAULT values. This is critical, especially if you are troubleshooting a problem.  To perform a reset, press-and-hold the [Reset] button, power-on, release the [Reset] button when the lights begin to flash.
  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 as the “URL” to gain access to the radio’s management console.
  4. Enter “ubnt” as the administration account and “ubnt” as the password.

  • 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.

SOHO WiFi Router

Wiki BeansTalk-55x_WiFi_SOHO_Router.pngRather 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 to use 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 Because each router is different, please refer to your router manufacturers FAQ for assistance.

Bandwidth Requirements for HD Video Streaming

If there isn’t a dedicated internet connection available, streaming can be achieved over 3G/4G, WiFi, or a shared network; however, delivery using these methods increases the likelihood of a failure and is not recommended.


System Center 2012 Overview

Configuration Manager lets you deploy software to employee’s devices and computers, inventory their hardware, push out OS / software updates as well as deploy OSs to bare metal computers. New in Configuration Manager 2012 is user centric management of devices and software with the concept of a user’s primary device(s), self-service software catalog, management of mobile devices, a vastly simplified infrastructure hierarchy, remediation of configuration drift through settings management and Role Based Access.

Virtual Machine Manager manages your fabric infrastructure for virtualization: hosts, clusters and networks from the bare metal to the ultimate abstraction in private clouds. The 2012 version has changed fundamentally from its predecessor in the overall scope by now managing the entire fabric, creating Hyper-V clusters from bare metal, managing resource and power optimization natively, interfacing with Hyper-V, VMWare ESX and Citrix Xen server hosts and orchestrating patching of clusters. There’s also a Service model that lets you deploy (and subsequently update) entire groups of related VMs for a distributed application, there’s Server App-V application virtualization deployment, built in High Availability for Virtual Machine Manager itself, storage control (iSCSI and FC SANs) and built in self-service with Role Based Access control.

Operations Manager keeps an eye on your servers (physical and virtual), OS (Windows and Unix / Linux), applications (All Microsoft, many, many third party and Java application servers) and your networks through Microsoft and third party Management Packs that contain knowledge about each component. New in 2012 is a simpler infrastructure with built in High Availability, much better and easier network monitoring, enhanced dashboards that can be published to SharePoint for wider audiences, Application Performance Monitoring (formerly known as Avicode), Java Enterprise Edition (JEE) monitoring and enhanced functionality and security for *nix monitoring.

Data Protection Manager is the best backup product for Microsoft’s workloads, following supported processes to backup from Disk to Disk, Disk to Tape, Disk to Disk to Tape as well as Disk to Disk to Cloud. New in 2012 is a centralized console (through Operations Manager) that can manage hundreds of Data Protection Manager servers (including DPM 2010), a new console UI, scoped consoles for troubleshooting, Role Based Access, improved Item Level Recovery (ILR) for recovering files from within VMs that have only been backed up through a host level backup, much faster SharePoint recoveries and certificate based communication for workgroup data sources.

Orchestrator (formerly known as Opalis) is a newcomer in the Service Center 2012 suite but it’s very important as it integrates and links the other components through automation. Via a Visio like interface Activities are linked together into Runbooks that can then automate IT processes on demand; Runbooks can be started from a web interface or from Service Manager or any other product that talks to the new Orchestrator Web Service. The true power of Orchestrator comes in the form of Integration Packs that allows it to “talk” to many other systems, including all the components in System Center 2012 as well as earlier System Center versions and many other third party systems, giving you a true automation engine to better provide IT as a service.
