Further information & work around: I have discovered that Network Manager writes the WEP passphrase to /etc/network/interfaces as plain text despite selecting Hex. I can get my network working with static IP iff I manually change /etc/network/interfaces and enter my WEP passphrase in Hex. The result of this intervention is the I can get wireless working with static IP but nm-applet no longer does its job and the routing table comes up misconfigured(ie. sends internal traffic to eth0 instead of wlan0. I assume nm adjusts this normally but my intervention stops this being properly configured at the time the network is being brought up). To have the routing table come up in a working form I have had to remove all references to eth0 in /etc/network/interfaces.
Also note: I now think that avahi error was a symptom & not the cause as I get no error message from avahi now. But also note that avahi enters items in the routing table which are irrelevant to my network - not sure if this is a bug or not??? I think avahi is entering this line in routing table: 169.254.0.0 * 255.255.0.0 U 1000 0 0 wlan0 Also note: The above mentioned desktop slowdown is very real when I have no network connection (a common situation with a laptop). The effect is immediate once the network is lost. -- Wireless won't work unless 'Roaming mode' selected https://bugs.launchpad.net/bugs/110187 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
