After receiving a very informative comment from NetworkManager Dan Williams (see the upstreams linked bugreport: http://bugzilla.gnome.org/show_bug.cgi?id=541816#c2 ), it is very likely this bug is really a combination of one or many mac80211-based driver bugs as well as bugs in wpa_supplicant.
@Brian Pitts, @rihasant, @dnel,@dlgandalf: You all seem to be using mac80211-based cards/drivers, which makes it even more viable. @Francesco: Since you are using ipw2200, Bug #75358 may be more appropriate for you. Dan Williams also replied in a similar manner here, but mentions a ipw2200 patch suggestion as well: http://www.nabble.com/NM-0.6.5-Great-Problem-td18027324.html kernel (wireless-testing.git): 872ba53395b2a8be08c3ea2d39e225e5b4a8cb40 mac80211: decrease IBSS creation latency 507b06d0622480f8026d49a94f86068bb0fd6ed6 mac80211: send association event on IBSS create Two following four patches was suggested to be able to create Ad Hoc networks using 80211-based drivers: wpa_supplicant: [PATCH] wpa_supplicant: give adhoc associations a bit more time - http://lists.shmoo.com/pipermail/hostap/2008-June/017908.html [PATCH v2] wext: handle mode switches correctly for mac80211 - http://lists.shmoo.com/pipermail/hostap/2008-June/017907.html According to the following changelog, the two mac80211 patches has been incorporated into the mainline kernel by 2.6.25.6-1: http://lists.rpath.org/pipermail/foresight-commits/2008-June/024368.html The wpa_supplicant patches seemed to have been applied since version 0.6.3-2 (https://launchpad.net/ubuntu/+source/wpasupplicant): * Add 52_handle_mac80211_mode_switch.patch to enhance handling of mode switching for mac80211 using interfaces. * Add 53_give_adhoc_assoc_more_time.patch to give adhoc associations a bit more time. Thus, it would be very interesting to hear if this problem persists in the current Intrepid development version (it oughtn't...)! Do we have any brave Intrepid tester that can confirm or approve that these patches have fixed the issue? ** Summary changed: - Can't create new wireless network + Can't create new wireless network using mac80211 based drivers ** Description changed: - Binary package hint: network-manager - Hi, I am trying to create a new wireless network (particularly, with no encryption) with the gnome applet. However, I just get the message "Trying to connect to wireless network «(null)»". Then, after a couple of minutes or so, it gets back to the cabled connection and no wireless connection is created.
