Yes I have and it takes about 1.5 hours to download. I even put a dedicated 802.11b access point in the room to make sure it has a good signal. I did buy a microsoft 802.11b card through Ebay (it is also a Prism chipset card) and it will download the latest firmware in about 30 minutes but after finishing the download it reboots and it will constantly give the pulsing "O" - nothing ever appears on the small LCD display. The card must not be totally compatible with the firmware. If I take out the microsoft card and re-insert the Philips card it will boot properly and do its usual sleep problem.
