What does Load threshold violation reported by '802.11b/g' mean?

I am assuming it is too many laptops on an access point. This environment has 24 laptops on a cart used in 1 room so shouldn't the controler divy them up between the 2 antennas  in the 1142 which is sitting right above them?

thanks

Gary

Hi Gary,

I think the user experience would improve greatly if

you deployed the 1140 series AP

With the greater bandwidth available with "N" 24 users

wouldn't be as problematic.You may still get the alarm

depending on the threshold you have set.

Cheers!

The AP doesn't work like that.  The antennaes work in "diversity" mode.

Hi Gary,

Just to add a note here to the good info from my friend Leo (+5 ponts L-Man)

You are most correct about the nature of this alarm;

WCS Message AP ''{0}'', interface ''{1}." Load threshold violated.


Symptoms A radio interface of an access point is reporting that the client load has
crossed a configured threshold.


WCS Severity Minor.


Probable Causes There are too many clients associated with this radio interface.
Recommended Actions Verify the client count on this radio interface. If the threshold for this
trap is too low, you may need to readjust it.


Add new capacity to the physical location if the client count is a frequent
issue on this radio.

As Leo noted, the dual antennas in "Diversity" mode won't help to mitigate

this issue. Only adding another AP can help load balance the client load

Cheers!

That room is an island in that it is surrounded by double block hallways etc. The 24 laptops have N in them but the AP is the 1131. I have 1142s in most of the rest of the building and they are the more expensive N variety. Would using that type of AP be better than the 1131?

thanks

Thanks Rob,

That was what I figured. We had about 40 1131s from previous installs but the rest of the 170 APs are the 1142s. I may just swap out and put in 1142s for any classrooms that frequently use 24 laptops. Of course they are not cheap by all means.

Hi Gary,

I hear you man

We are replacing all of our current 1130, 1240 series AP's on our

Campus now as the number of student/staff/faculty laptops increases. The first

area we are converting is our Library which frequently sees the same

issues as your classroom example. In our testing the conversion to

"N" standard AP's makes a considerable difference like you nicely noted.

Cheers!

Rob
