Hi Kel, Thank you for the links.
> Well, in my experience these gui apps for configuring wireless on linux > really cause more trouble than they are worth. Maybe, but: 1. You and I are fine with console based configuration tools, but many people, including the owner of this laptop, will not touch them. The majority of users really do want a GUI. 2. Software should never crash. Error messages are fine when something goes wrong, but a crash is never acceptable, especially in kernel mode. So "don't use a GUI config tool" is only valid as a temporary workaround, not as a permanent solution. That said, I'm here to help, not to belittle your efforts. Let me know if there's anything I can do. I'm thinking about having a look at the code (ath_ioctl_giwscan). I'm pretty good with C, though not at all familiar with Linux kernel code. But it might be worth a shot. -- graham
