I think we fixed this in 2.6.26.x/2.6.27.x-ish. Is this still an issue? Yes, it is partly an issue. The connection can now successful establish every boot, but always with this error: ioctl[SIOCSIWAUTH]: Operation not supported WEXT auth param 4 value 0x0 - and the link quality is pretty low, even if i place the AP next beside me. (but this can be a issue with my card, maybe...) $ iwconfig wlan0 [...] Link Quality=16/100 Signal level:65/65 [...] I'm using now: $ modinfo rtl8187 filename: /lib/modules/2.6.26.6-49.fc8/kernel/drivers/net/wireless/rtl8187.ko license: GPL description: RTL8187/RTL8187B USB wireless driver author: Andrea Merello <andreamrl> author: Michael Wu <flamingice> srcversion: E9AACD354F4F5132591DD84 [...] depends: mac80211,eeprom_93cx6,cfg80211 vermagic: 2.6.26.6-49.fc8 SMP mod_unload 686 4KSTACKS $ uname -a Linux localhost.localdomain 2.6.26.6-49.fc8 #1 SMP Fri Oct 17 15:59:36 EDT 2008 i686 i686 i386 GNU/Linux best regards Hmm, the WEXT message is due to some mismatch between kernel and user tools, how's that possible? Do you have a self-install wpa_supplicant, etc? The link-level, etc is being improved at the moment... Mmh, i'm using all the stock rpm's, that comes with Fedora. wpa_supplicant-0.5.10-6.fc8 wireless-tools-29-0.2.pre22.fc8 I played around a little with wpa_supplicant and found, that this errror disappears, when i start wpa_supplicant with the "-w" option (wait for interface to be added, if needed.). So there might be some timing issue elsewhere? Anyway, i think this may not related to the kernel driver? thanks NetworkManager is responsible for launching wpa_supplicant on demand, I think. The link quality, etc are being improved as we speak (i.e. my laptop has some prototype patches I am testing from somebody else) - and some of fc9 kernels are gradually having them, so it will gradually filter down. OTOH, there are a lot of wireless-related improvements, so one of these day you should upgrade to fc9. (and in a few weeks, fc10). I'm not using NetworkManager in F8, to many problems. ;-) Therefor i am using wpa_supplicant without the dbus interace (-u). At the moment i'm still stick to F8 and wait for F10. I'm pretty fine with this "solution" right now and i can live with this low Link level thing for now. So works for me. Thanks I switched now to F10. The new module is working fine (with both NM or standalone wpa_supplicant), but still with very low link quality. I have to use it now on a "real" link and i'm not able to get much traffic over the air. Please can you provide one of these "prototype patches"? I'm willing to testing and/or proofing. Thanks! Download a current compat-wireless tar ball and give it a spin. I think you will find it work even better than what f10 gives you. http://linuxwireless.org/en/users/Download Any issues with compat-wireless, write to the linux-wireless mailing list and cc the 3 of us.
