Re: DRIVER NEEDED: Broadcom 802.11g (Windows XP Professional) [PCMCIA]
802.11g is not a model number nor a chipset number... it's a protocol that could apply to hundreds of different network cards. Please provide a valid model number and also say if this is a separate add-on card or integrated on the motherboard (I realize you said pcmcia but not every one gets it right). If it came pre-installed (or packaged with) your computer, please include the computer/motherboard brand and model.
Also please note that Broadcom is a chipset maker, they do not make network cards.
