broadcom bcm4318, slaby signal

Nazdarek, mam tuto nestastnu kartu v NB, nakoniec sa mi ju podarilo rozbehat cez bcm43xx-fwcutter natolko ze beha. (pri pouziti ndiswrappera /pod odstraneni modulu bcm43xx mi eth1 zmizne, takze mi je ndiswrapper na 2 veci). k veci: wifina ide, teda aspon sa tvari (az na diodu, ta svieti stale), problematicka je ale intenzita signalu. ked sedim u mna v izbe, kde je AP, apcko mi hlas intenzitu sig. cca 40%. Ak sa prepnem do windowsu a napojim sa, intenzita sa pohybuje okolo 80, 90%. Karta nepodporuje (aspon mi hlasi) nastavovanie 'power' ani 'tx-power', proste vyleziem s bookom do obyvacky a mozem si piskat...
