WLC compatibility anWireless card RALINK 2561 T on a light Pc (NEC TCM 160)

Hello i have strange roaming conditions with a NEC light Pc (no hard drive, flash card and windows XP embedded) and an integrated wireles card RALINK 2561 chipset.

I have put latests drivers for XP on xp embbeded NEC pc.

WLC are 2 WiSM in version 3.2.116

Access points are 1131LAP

My case is : a corridor with 2 LAP

i bootup the NEC-PC and associate to the right AP (nearest AP)

I walk along the corridor, and when i am under the second AP, i am still attached to the first AP, so i keep on walking and i stay associated to the first one with some lost ping and very bad times (1 to 2.5 seconds for exemple)

In order to roam i have to walk and go outside the corridor where i don't see anymore the first AP in order to roam to the second AP.

That's quite strange becaus with a "normal Windows XP" i roam 2 or 3 meters before i walk under the second AP.

I will try to upgrade controller but i think the trouble is more in drivers or windows XP embedded;

I use Windows zero config in both cases (xpe or xp pro).

Does anybody have seen this with this card ? with windows XP Embedded ?

Thanks for your help.

Upgraded to

same trouble with roaming and windows XP embedded wifi client

With ralink client and parameter "fast roaming" set at -60dbm => roaming is better.

but without ralink wifi client : not working better.
