Aggressive Load Balancing?

[Sergey Tarasevich]

Hi! There is a question about an aggressive load balancing. In this mechanism will work Intra-Controller Roaming? Does balancing with associated clients or it only happens when you connect to an access point?

Don't ever use it! That's all I can say. To make it simple, many clients don't support status code 17 which is used to try to force clients off to hopefully attempt association to another AP. your clients will just not connect is what you will see.

So don't even research it any further and leave it disable.

OK. Then the following question. For example, I have a room and 200-300 clients in it. How then to load balance between access points, so that did not happen, which is a single access point associated 9 clients, and the second 30 clients? What can you do in that case?

Tweak your RF. You need to adjust the TX power and the data rates. The reason you have one AP with 9 clients is probably because that AP has the lowest TX power setting like 7-8. Make each AP the same TX power level, depending on how many AP's and how big the room is. You will need to play around with this and the data rates to achieve what you want.

Here is a guide to look at too

What you see is normal if you let RRM alone with no tweaking by the way.
