DWL-520E (works!)

Here's what I did to get the card working:

- I made the following source code changes:

A) as was specified in the DWL-650P thread, I changed "*pos++ = 0x03;" in
prism2_srec.c to "*pos++ = 0x07;"
B) I also uncommented PRISM2_DOWNLOAD_SUPPORT in hostap_config.h

- I built and installed the driver
- loaded the PCI module with the no_primary option set to 1.
- loaded the WEP module.
- downloaded the appropriate firmware, following the DWL-650P thread.
- card was operational - ran "ifconfig wlan0 up".
- I then configured it to my network using iwconfig and ran dhcpcd.
- I was online.

Hope that helps.

I was using a program called kwifimanager to query the status of the card,
that was probably what was causing the SIOCGIWENCODE message.

That's nice to hear. What did you need to change in the driver or

I modified no-PRI f/w mode to automatically determine SRAM type and card
type (PCI or not). Could someone with DWL-520 E (or any other PCI card
without PRI f/w in flash) test whether the current CVS snapshot is enough to
work with such a card? At least, the new version seems to work fine with
DWL-650 P1.

8B2B is SIOCGIWENCODE. In other words, something is trying to read WEP key
configuration from the driver, but this program seems to have a bug (invalid
buffer passed for SIOCGIWENCODE). This could be a wireless status tool, etc.
