Public bug reported: Binary package hint: gnome-system-tools
Version: Dapper Drake 6.06 LTS i386 Steps to replicate: 1.) Boot with "old" access point configuration: (HOMEACCESSPOINT, note - no WEP key) $ cat /etc/network/interfaces auto eth1 iface eth1 inet dhcp wireless-essid HOMEACCESSPOINT 2.) Scan to find "new" access point essid: $ iwlist eth1 scanning eth1 Scan completed : Cell 01 - Address: 00:20:A6:62:3E:11 ESSID:"WORKACCESSPOINT" Protocol:IEEE 802.11bg Mode:Master Channel:6 Encryption key:on Bit Rates:54 Mb/s Extra: Rates (Mb/s): 1 2 5.5 9 11 6 12 18 24 36 48 54 Quality=100/100 Signal level=-159 dBm Extra: Last beacon: 48ms ago 3.) Run network-admin and configure: $ gksu network-admin Network name (ESSID): WORKACCESSPOINT Key type: Plain (ASCII) WEP key: WORKWEPKEY Connection settings: Configuration: DHCP 4.) After OK (twice) and a few minutes delay until network-admin closes: But no IP address. I then check config: $ cat /etc/network/interfaces auto eth1 iface eth1 inet dhcp wireless-essid WORKACCESSPOINT wireless-key s:WORKWEPKEY 5.) Looks ok, so I try restarting networking: $ sudo /etc/init.d/networking restart One of the last messages is: No DHCPOFFERS received. 6.) Make no changes and reboot Then authenticates to access point and works great, *** OR ***** 6. (alternate) specify essid, channel, and key $ sudo ifdown eth1 $ sudo iwconfig eth1 essid "WORKACCESSPOINT" key s:WORKWEPKEY channel 6 $ sudo ifup eth1 Then authenticates to access point and works great, Expected behavior: After changing configuration in network-admin, the new configuration settings should be used, just like they are used during boot. I do know that doing iwconfig without explicitly setting "channel n" would not result in a connection. Not sure if it is relevant, HOMEACCESSPOINT is on a different channel than WORKACCESSPOINT, and HOMEACCESSPOINT does not have a WEP key whereas WORKACCESSPOINT does. When I go the other direction, use Wi-Fi at home, I need to do: $ sudo iwconfig eth1 essid "HOMEACCESSPOINT" key off channel 1 Hardware: HP Pavilion zx5078cl $ lspci |grep Broadcom 0000:02:02.0 Network controller: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller (rev 03) ** Affects: gnome-system-tools (Ubuntu) Importance: Undecided Status: Unconfirmed -- Changing ESSID requires reboot or, or manual iwconfig for changes to take effect https://launchpad.net/bugs/80499 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
