In hostap mode, and without WEP, it works fine. In hostap mode with WEP enabled, the laptop cannot get an association. As soon as I turn WEP off on both ends, the laptop can get an association. I'm using Hex keys, and even simple unambiguous keys (like 0x11111...). I've tried 64 and 128 bit WEP. I've asked about this in the -stable list, and gotten a couple of "me too"s from people with other wireless cards, but no answers. So I don't think it's necessarily a case of user error. (Yes, I know WEP is not much chop but it's good enough to stop casual leeching of my cable link.) [Severity is Serious/medium because it is very unwise to run wireless without some sort of security.] As an aside, I can't go from hostap mode back to ad-hoc mode without a reboot, it gets ENXIO. Looking at if_wi.c, something like this appears to be deliberate (in wi_media_change(), line 2846ff), but I think the ENXIO is coming from sys/net/if_media.c:ifmedia_ioctl(), due to ifmedia_match() failing, which is very very odd..... >How-To-Repeat: # ifconfig wi0 inet <whatever> netmask <whatever> ssid <whatever> wepkey <whatever> (Put laptop in Ad-Hoc mode with same key) Note that the link works. # ifconfig wi0 wepkey <whatever> mediaopt hostap (Put laptop in BSS mode) Note failure to get an association. # ifconfig wi0 -wep (And turn WEP off on the laptopo) Note the laptop is able to associate. # ifconfig wi0 mediaopt adhoc ifconfig: SIOCSIFMEDIA: Device not configured # >Fix: None known. Possible work-around is to use IPSEC or PPPoE for network security. I'm willing to play around with this box if anyone can give me some pointers or wants me to try some debugging. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
