I too have been experiencing these problems with the Atheros 5212 Chipset (both IBM Thinkpad buildin and Netgear external PCMCIA/PCI adapters) and network-manager when connecting to hidden access points - though all my adapters work with K/Ubuntu 6.10. I have tried to locate the problem, as I suspected the driver to be the problem (Ubuntu Restricted Modules), but must admit I was suprised to find that it's the network-manager or knetworkmanager that must be the problem.
Yesterday I tried to use wpa_supplicant from the console line instead. First I created a wpa_supplicant.conf file from the template under /usr/share/doc/wpasupplicant/templates, then : sudo iwconfig ath0 essid MYSID sudo wpa_supplicant -Dwext -iath0 -c/etc/wpa_supplicant.conf -dd sudo dhclient Works every time and after reboot too, so now I can't help suspecting the network-manager. What's odd is that K/Ubuntu and network-manager seems to work flawless with Intel 2915A/B/G and 2200B/G (Buildin IBM Thinkpads) adapters against the same hidden access point. I seems that problems much alike this have been reported in several other bugs (often under linux-restricted-modules) in launchpad under Ubuntu and network-manager since version 7.04, but a great deal of the bugs unfortunately don't state which WiFi chipset is used. But why can't network manager handle the Atheros chipset against hidden AP, when it can handle Intels flewlessly ? - could the difference between hardware be the reason that this bug has not yet been solved ?. -- A bug between Atheros Communications AR5212 802.11abg nic and Ubuntus network applet https://bugs.launchpad.net/bugs/111068 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
