Mikrotik Sextants on their way
The new MikroTIk SEXTANT is very similar to the popular SXT unit, just slightly bigger. Inside is the brand new RB711-5HnD dual chain wireless device, with high performance, high output power, and low power requirements.Easy to use and quick to deploy, SEXTANT is ideal for point to point links.
I think this will be your new favorite CPE so hurry and come get some!

Keeping RouterOS Queues on Top
One frustration I have recently dealt with is the dynamic simple queue behavior in MikroTik RouterOS that started sometime after version 3. Somewhere in there, they started adding new, dynamically created queues (created by MikroTik HotSpot or UserManager/PPPOE) to the top of the list instead of at the bottom.
This really causes an issue with static queues you might have in place for prioritizing traffic like VOIP. When the dynamic user queues are inserted above your VOIP queue, VOIP traffic from that user's target IP no longer has priority. I contacted support@mikrotik.com and Janis Megis from MikroTik indicated it was a requested feature that would be added at some point in the future. This caused me a lot of grief recently workign with a large HotSpot deployment on a RouterBoard RB1200.
Until then, here is a solution.
Create a script with the following code:
/queue simple move [find name="VOIP"] [:pick [find] 0]
In this code, I have a simple queue named UDP that I always want at the top of the list of queues. You can repeat this code for other queues to be placed below this queue like this:
/queue simple move [find name="VOIP"] [:pick [find] 0]
/queue simple move [find name="VIDEO"] [:pick [find] 1]
/queue simple move [find name="SSH"] [:pick [find] 2]
Then, create a scheduler job to run the script every 10 seconds or so and you should be in QOS heaven!

This is Mac Heaven
After several weeks of arguing with my Windows 2003 server and the interoperability issues it now has with Mac OSX Lion, I bit the bullet or more appropriately drank Steve Job's kool-aid and spend the evening configuring my new Mac Mini server in my hotel room. Four hours from home and teaching a MikroTik class in Dallas, I was bored and angry that my Time Machine backups weren't working any more because Windows 2003 server's Appletalk protocol has not been updated. Blame it on Lion or blame it on me for still using Winblows as my server, whatever, it was time.
Off to the store I went and am now the owner of a Mac Mini (our new file server, contact server, calendar server, etc.) and a Time Capsule for our home backups. This is Mac heaven.
Since I didn't have a monitor, I jacked the hotel television (thank goodness for HDMI inputs)
hooked up the new mac mini and started downloading Lion server while my Time Capsule backed up my 15" Mac Pro and served up the wireless. This is Apple bliss!
Thank goodness I am able to watch a movie on my I Pad while I watch Lion install on my Mac Mini and type my blog on my MacBook Pro. Heaven I tell you!

Dallas MikroTik Training Started Today
MikroTik MTCNA Training started today in Dallas, Texas with a great group of students. Typically we spend a lot of time with the basics but this group has a great grasp of basic networking so we moved quickly today. We started with the OSI Modem and ended with firewalls. Tomorrow we start the day with bandwidth limitations and hope to finish early on Wednesday.
Are you ready to train? Our next MikroTik Training is in Las Vegas, NV, in October. Send us an email or visit us at LearnMikroTik.com.

Netscape, are you kidding me?
While navigating around the AT&T wireless site today, I noticed something kinda funny. The favorite icon is Netscape! If you don't understand what that is, you won't find this funny...

OmniTIK Now Available
We just got a load of the new OmniTik's, Mikrotik's newest integrated solution. OmniTIK is a weatherproof outdoor AP with dual-polarized omni antennas - the perfect companion for the SXT, or for any other 5GHz 802.11a/n standard device.
Weatherproof, durable and ready to use. It has five 10/100 Ethernet ports, PoE support and a built-in 400mW 802.11a/n wireless radio. It supports Nv2 TDMA technology with up to 200Mbit aggregate throughput.
LED signal indicators on it’s back are fully customizable, show Ethernet activity or wireless signal - or any other information from RouterOS.
The USB port gives the ability to connect a 3G modem or a storage drive.
I am thinking of applications for this device including wireless networks for apartment complexes, as a backbone for an RV park WiFi, temporary internet access venues. etc. What is missing in my opinion is a second radio. I would rather sacrifice the dual chains for 802.11n and instead add a second radio running 2.4 GHz. A dual band mesh node at this price point would be awesome and could lend itself to municipal WiFi deployments, etc.

Script to Set Rate Limits for Self Created Users in MikroTik UserManager
Usermanager is MikroTik's version of radius and is a great way to centralize AAA on your network. In addition, it also has facility to allow users to buy credits on your network through hotspot, however, the only limitation it can automatically create is a time limitation. You can create packages that allow access for a day, week, month, etc., but in order to set a rate limit for that customer and their package, you have to manually make that change to the user in Usermanager.
I needed a way to automatically accomplish this so I enlisted the help of my script guru, Andrew Cox. Although I have never met Andrew in person, I can tell you he is a bright guy who is one of the few people I know that truly speaks MikroTik's scripting language. As usual, Andrew rose to the challenge and wrote a few lines of code that function perfectly.
A few notes, first the script uses the user property "credit-price" to determine which package the customer purchased, therefore, you need to have unique prices for each rate limit. For example, if the Gold package is 128k/64k and costs $25, then users that buy the 64k/64k package that costs $25 will get the same rate limit. In this example, just change the price slightly on one of the packages and it will work correctly. For example, make the 128k/64k package $19.95 or something similar.
So, here is the code, past it into a new script item through Winbox, set the scheduler to run it once every minute or so and you will enjoy the benefits of automatic rate limits with self created user accounts.
