Error for wireless request "Set Mode" (8B06)

Im using Fedora 8, when i try to activate my wlan0 I get the following error and the computer locks up

Error for wireless request "Set Mode" (8B06) : SET failed on device wlan0 ; Invalid argument.

My network controller is a RaLink RT2561/RT61 802.11g PCI and it is recognizing it.

any ideas?

I assume you're using rausb driver from serialmonkeys? (I believe it is included in latest fedora 8 kernels).

The driver had a bug in it (at least some version did). I never managed to set encryption for my wlan, and when I first used it with open wlan, whole machine frozen. I managed to make it working with open wlan by enabling IRQpolling on kernel startup at grub's config.

I get the same error message, but it connects and works correctly. However sometimes I lose my connection (maybe it's an ISP problem). My wireless card is also a PCI Ralink RT61.

Actually my Fedora 8 used to freeze sometimes too, but I found that it was a hardware issue: the pci slot was dusted.

Could you give some more details? What about the device settings?
