The D830 driver for the Dell Wireless card says it is compatible with Windows XP 64-bit even though I know Dell does not officially support XP 64-bit for the D830. I know for a fact the wireless card works as I just swapped it with another D830 running XP 32-bit and it works perfectly. I have downloaded every wireless driver on Dell's support page for D830 wireless cards that state compatibility with XP 64-bit included older versions of the current driver. So far I have been able to load all drivers except the modem (which I do not need). Any help would be appreciated.
