1240AGP Access Points/4402 Controller

Unanswered Question
Mar 5th, 2007

To clarify for me - I have a 4402 controler set up, with 2 APs in this site. How many people can can connect to a 1240agp AP before degradation starts? and how does the Laptop (wireless user) know which AP to go to? Is it just the closest one, and how does the users recognize which one is the closest?

New technology for me and will be setting up at various sites. Great fun!

Theresa

Hi Theresa,

Here is todays reading assignment :) With great answers from Scott,Eric,John,Steve,Robert and many others

Number of Users per AP:

These are questions that come up all the time.As you can see from the answers in the links below,there are alot of factors that come into play.The consensus from everything I have read would be 20-30 users per AP depending on actual applications etc.Have a read for some great answers provided in this forum by some "hands on" experts:

As far as Roaming goes,this is controlled by settings on the client side that determine when to move (based on Signal strength etc) have a look at these answers;

Q. Why does my client card not associate to the closest access point?

A. If you have multiple access points in your wireless topology, your client maintains an association with the access point with which the client originally associated. The association remains until the client loses keepalive beacons from that access point. The client then seeks out another access point and attempts to associate to that access point, if the client has sufficient rights and authorization on the new access point.

Make sure that available configured data rates match between a given client and the access point desired. An auto setting on the client card does not automatically match everything, but allows the client card to rate shift among available rates that the access point advertises.

From this good doc;
