i recently got an acer ex4420 that came with vista home premium. it had signalup technology and i was able to see 3 networks in my area. i took off vista cus i didnt like it and put in xp pro sp3. everything works except i cant see the 3 networks in my area anymore. i have a feeling signalup is a vista exclusive, but im not an expert in this field. does signalup work for xp? if so, how do i get it to work?
