Hi, yesterday I've done a release upgrade from 10.4.1 LTS to 10.10 and I faced the following issues: 1) br0 does not bridge anymore eth0 and wlan0 (I have a DNMA92 wireless card that runs ath9k drivers) at startup even if specified in /etc/network/interfaces: [CODE] auto lo iface lo inet loopback pre-up /sbin/iptables-restore < /etc/network/firewall-rules.conf # The primary network interface auto eth0 iface eth0 inet manual auto wlan0 iface wlan0 inet manual post-up /sbin/iwconfig wlan0 txpower 17 auto br0 iface br0 inet static address 10.0.0.1 network 10.0.0.0 netmask 255.0.0.0 broadcast 10.255.255.255 bridge-ports eth0 wlan0 [/CODE] If I reboot the server, then [I]brctl show br0[/I] shows only interface eth0.. before 10.10, everything worked without problems... I've solved the problem adding to the above code [I]pre-up /bin/sleep 5s[/I] and it seems to work now... maybe wlan0 is not ready when the brctl tries to add it to the bridge br0? Any idea? 2) is there a configuration file or a particular statement that I can use to specify that I want wlan0 to work at 17dB instead of 27dB? I've added the post-up directive above to change the txpower when wlan0 is brought up, but maybe there is a better way (such as an option to pass to the ath9k kernel module..) 3) Hostapd seems to have problems at boot and if I try to connect to the WPA2 protected network after a server reboot it keeps telling me that I'm using a wrong password... I can not find useful messages in my syslog... if I restart the hostapd, everything works.. again, it worked before the upgrade. At present time I've solved the issue by adding a post-up directive to br0: [CODE] auto br0 [...] post-up /etc/init.d/dhcp3-server start post-up /etc/init.d/linux-igd start post-up /etc/init.d/hostapd restart [/CODE] As you can see, I need to start again also linux-igd (the upnp daemon) and dhcp3 since they fail to start up since the bridge is not ready yet when their respective startup scripts are invoked... maybe you have some useful ideas also to avoid these post-up directives and to tell dhcp3 and linux-igd to start after br0 is ready or to keep trying until br0 is ready. -- -------------------------------------------------------------------------------------------------------------- | Gianni Costanzi (<a href="mailto:gianni.costanzi@gmail.com" target="_blank">gianni.costanzi@gmail.com</a>) | <a href="http://utenti.lycos.it/giannicostanzi/" target="_blank">http://utenti.lycos.it/giannicostanzi/</a> | | My Fotoblog: | <a href="http://giannicostanzi.fotoblog.it" target="_blank">http://giannicostanzi.fotoblog.it</a> --------------------------------------------------------------------------------------------------------------
