my customer use wireless network (controller based).

WLC 4404(4.2.130) + LAP(1131) + WPA1(TKIP) + Radius(ACS4.1)+HREAP

some client disconnect frequently, so we update client wireless driver, and change channel & power ,WLC RRM fix

so we change LAP to Autonomous AP,

all fine.. why?

i dont understand....why client disconnect?

Kim,

Are all the ap's H-REAP and when troubleshooting, is the issue in a specific area.  When you changed the AP's to Autonomous, were you still authenticating back to radius?

KIM:

Many problems are derives from customers, VISTA,  cause many problems, and as for XP, must have all the patches,

ok. I understand your problem, I spend the same a few  months ago with the same infrastructure, raise a case with Cisco, which  told us that the problems are the type derives by network design, as  ap, have a limit, in my case, had 20  for the model 1130, as probedor I observe, that the problem was derived  from customers, points out that the ap, the only thing it does is  radiate the signal, but the client does is the one who initiates the  negotiation.

As  recommendation.
Check the number of customers each AP supports.
If possible perform a site survey, the controller Check how  many customers are associar to each AP, it is possible that more than  enough capacity.
For now is all I can think of.

thank you... your reply....

AP is enough.....and Client Driver all Update

I think that auto-AP NO RRM fuction.. but LAP RRM fuction enable

Channel Interference may give rise to Client Roaming..although Channel & Power is fix

I set-up more less tight Performance profile on Controller (Cisco recommand : Controller very tight)

I attach channel analyze report

result although Performance profile change more less tight on LAP environment

I think that controller base wireless inconsistence on heavy Channel Interference environment

thank you..!! please reply
