Wireless Bandwidth Hogs - how to combat

Greetz:
I (try to) run a WISP and have five APs covering my neighborhood, but this question focuses on one area, the main AP (which serves the other multipoints in an omni radius). This main point is an Engenius 3220-ext AP that uses Access Control to allow only certain users (APs or Client Bridges) via MAC address.

The system is fed by a T1 line through an Adtran NetVanta 3430. The Adtran has no QoS policy enforced.

I installed PRTG Traffic Grapher on a server and monitor the main APs for latency and bandwidth. The graphs have revealed that when any single  user grabs 300k or more of the bandwidth, other users experience service disruption. Bandwidth use directly correlates with latency.

Two questions then:

1. what is(are) the best tool(s) to use to find out what kind of traffic is causing the bottleneck and where it comes from?
2. Can anyone suggest a QoS reference for an Adtran NetVanta, or would volunteer to help?

I can't help you with your questions, but I do have a simple solution.  If you purchase a Linksys WRT54G and install the open source firmware DD-WRT, you can do everything you're looking to do.  The total cost is only $50.

You should google DD-WRT.

The biggest problem with this solution is that I must have a outdoor, weatherproof antenna.

perhaps this turn-key solution might be of interest?:

http://www.duxtel.net

based on Mikrotik RouterOS which is also an excellent hardware to provide wireless hotspot, captive portal and traffic shaping.

Cheers!

I would love to try that out. Do you have a contact at the company or should I use the website contact? I have also done some research on NetEqualizer's "AirEqualizer" product. It costs $800 which is inexpensive compared to the main NetEq products. What does Duxtel equipment cost?

In re: previous posts on this I found this link:
http://en.wikibooks.org/wiki/DD-WRT/Features
However, I have not found a weatherproof, external antenna that will flash with DD-WRT OS. Does anyone know of one?

Oops, I found the Duxtel outdoor at http://shop.duxtel.com.au/index.php?cPath=22_23 and it is the same price as AirEqualizer. I can't find the specs on it, tho...

Hi,

The linksys WRT is a domestic grade appliance.  It generally transmits at around 65mW, although I understand that there are some hardware hacks that will bring it up to 150mW or thereabouts.

The DuxMaster is a commercial grade device with a 600mW radio.  Add to that an 8dbi antenna, the range and sensitivity is far superior.

for additional details, you should contact the company direct.

Cheers.

Also,

looking over your existing soution, you wouldn't need an outdoor DuxMaster for that job.  You could easily get away with just an RB532 based router - a cost of probably less than $500 (AUD)

Cheers.

Since we never answered the question about outdoor WAPs, I gave this question a grade of B.
