Arjan, any ideas why building against the current kernel version wouldn't fix this? What card are you using? Thing is, this driver hasn't changed in ages.... So, what version of wireless extensions a driver uses is completely driver dependent (it isn't a core subsystem) /me swears about DRI all over again. wvlan_cs must not be implementing the versioning right. Assigning to kernel. :) You may want to try using orinoco_cs instead. Or, try the attached. (mmm, unitialized variables...) Created attachment 26091 [details]
you know, if wireless-tools is trusting this value, we should set it. :)
(warning: *completely* untested. code cut-n-pasted right out of orinoco_cs) I'd probably use orinoco_cs if I it would work :-). After modprobing it, no network interfaces appear. I wonder what's the problem with it. I pointed the WE problem to Jean Tourrilhes and he said the module is not up to date. So, your fix looks promising from that perspective. (unfortunately, I'm unable to test the patch at this point). I'm using Lucent WaveLAN 11mbit gold card. Pretty basic stuff. We (Red Hat) should try to fix this for the next release. The same also happens with orinoco_cs (2.4.7-0.9.1 or the like too). wvlan_cs updated as of 2.4.7-2.4 should be fixed in that Sorry to repopen old wounds. Note warning message on 8th line below. This is
the wvlan_cs driver.

On RHL71 (with updates) and Roswell both I get like: Warning : Device wvlan0 has been compiled with version 68 of Wireless Extension, while we are using version 11. Some things may be broken... wvlan0 IEEE 802.11-DS ESSID:"B022" Nickname:"WLAN" Mode:Ad-Hoc Frequency:2.422GHz Cell: 02:60:1D:F1:64:37 Bit Rate:2Mb/s Sensitivity:1/3 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality:0/92 Signal level:-102 dBm Noise level:-102 dBm Rx invalid nwid:0 invalid crypt:0 invalid misc:0 I'm using wvlan_cs driver. Please note that 'compiled with version xx' changes between consecutive 'iwconfig' runs between 0 and about 236. As Link Quality, etc. have never worked here, I believe this may be a problem with those (or some other value that changes all the time). A problem could be that wireless-tools is compiled against glibc kernel headers. However, recompiling with -I/usr/src/linux-2.4.6-3.1/include changes nothing (and wireless.h is identical anyway). Rebuilding will not help. I find this most odd.
