I'm having trouble with my prism card....

Make sure you have the most up-to-date firmware! It's 1.8.4 for most prism versions. See next question.

What's an easy, reliable way to update the firmware of my prism card?

I (DrDT) have updated the firmware of many different kinds of prism cards using this method (on Windows). It requires modified Senao drivers, the winupdate program, and the correct firmware files for your card. You can find the correct firmware types from this table . Match your "Component ID" (see hostap_diag under linux, or winupdate in windows will show you) against the table and you'll find what primary and secondary firmwares you need. Then you can find the latest primary (pL######.hex, where L is the letter for your primary type) and secondary (sL######.hex, where L is the letter for your secondary type) firmwares on sites such as

Most people will have cards of type 800C or 8013 in my experience; according to that table those types of cards require a "K" Primary and a "F" secondary. the latest versions of these are at (primary "K" version 1.1.1) and (secondary "F" version 1.8.4)

Make sure you have the right type of firmware, and no programs running/problems with your computer during the update. Any small error will permanently kill your prism card! Ask me in the channel if you have questions.

Here's my recommended procedure to update your prism card on Windows:

1) get the Senao prism driver 2) get the winupdate program 3) get the 2 firmware files which match your card, the primary and secondary according to the info above. 4) After removing any old prism drivers, install the Senao driver. Then go into your windows inf directory

5) When you insert your prism pcmcia card, it'll ask for a driver. Select "choose from list" in that box and

6) After installing the card, go to your prism card's driver's options and deselect the "update firmware" option

7) Install and run the winupdate program. Your card should be automatically selected. 8) Add the 2 fimware files above using the "file" menu. Those 2 files should be listed in the main winupdate box,

9) Press the "flash" or "update" button... I forget what it is. Anyways, it'll ask for confirmation and then will start

Again, if there are any questions, ask in the channel.

Help with windows specific stuff in NetworkCommands and AssociationWithNetworks would be greatly appreciated. I have pictures and commands for the orinoco software under windows that I can take care of, but anything else is fair game. Further wikiizing this page (like the lucent cards), and any further FAQ's would also be welcome :) --ForrestEnglish
