Ubiquiti announce Training course updates

linitx product Ubiquiti airMAX Certified Admin Course main image.Ubiquiti have renamed the existing UACA (Ubiquiti AirMAX-Certified Admin) and UUCA (Ubiquiti UniFi-Certified Admin) training courses. But this is not just about a simple re-branding.  Ubiquiti have announced that instead of the training being equipment specific, it will be more orientated towards the typical roles encountered in ‘Enterprises’ and ‘Carriers’.  Therefore with immediate effect the UACA becomes the UCWA (Ubiquiti Carrier Wireless Admin) and the UUCA becomes the UEWA (Ubiquiti Enterprise Wireless Admin). Enterprise training will therefore be based upon UniFi, AirVision etc. Carrier will be for example, more on AirMAX and AirFiber etc.

Tired of adverts in Skype?

If like myself, you are becoming tired of the Microsoft adverts within current versions of Skype, copy/paste this into your Mikrotik Router’s CLI (if it is providing you with your DNS Service).

/ip dns static

HowTo: Ubiquiti EdgeRouter performance testing

Ubiquiti EdgeRouter Lite 3-Port EdgeMAX Router
The EdgeRouter Lite from Ubiquiti promises excellent performance for a great price.
So what performance can you get out of it ?

We tested two things:

1) a typical routed configuration, including NAT, and stateful firewalling.
2) IPSec over a routed connection.

Here are the headline figures: (tests using iperf over TCP, details shown later)

1) 888 Mbits/sec routed

HowTo: IPv6 over PPPoE on the Ubiquiti EdgeRouter Lite 3-Port EdgeMAX Router

The new 1.2.0beta2 version of the EdgeMAX software on the EdgeRouter Lite has the following entry in its changelog:

[PPPoE] Add IPv6 settings for PPPoE client interfaces, which allows a PPPoE client interface to work with IPv6 address

So how does that work and how can we use it ?
Ubiquiti EdgeRouter Lite 3-Port EdgeMAX Router
Our ISP, Andrews & Arnold, provides native IPv6 over PPPoE, so we thought we would test it.

HowTo: Managing POE for multiple radios

A typical wireless broadband provider/WISP usually has multiple radios, each with their own POE connection.

Here’s a way of providing Gigabit POE with the ability to power cycle individual radios:

For Gigabit POE we use a MikroTik RouterBoard Gigabit Passive PoE Injector:

LinITX.com product Gigabit PoE Injector main image.

 

Each POE injector plugs into the main router and has  power fed to it  from a single 28V PSU via a relay, i.e. there is one relay per POE injector.
