de-activate internal card and using other (spetec)

[ataris]

Hello,

the network card that hat my orange m600 (qtek s200) works badly with cisco AP's in my work, but works with other normal AP's (linksys, etc)

I think taht perhaps can buy other wifi sd card, like SPETEC, but anyone know how-to de-activate the internal wifi card ?

or anyone know a software that allow me edit internal parameters ( buffer sizes, etc ) for the internal card?

Any suggestion are welcome,

Than you in advance,

Jose
