Hello, I've recently installed Kubuntu10.10 on a laptop Acer TM660 (rather old hardware now), running in 32b with a Centrino chip for wireless connection but I didn't find how to configure interfaces; in the menu to configure the network I was able to put parameters for new wireless connection but surprisingly there is no option to bind connection with a specific interface; thus, after that, there is no mean to set up interface as it is not yet configurated; command ifconfig -a gives: eth0 Link encap:Ethernet HWaddr 00:c0:9f:2e:d9:bf UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Packets reçus:0 erreurs:0 :0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:1000 Octets reçus:0 (0.0 B) Octets transmis:0 (0.0 B) Interruption:10 eth1 Link encap:Ethernet HWaddr 00:04:23:77:53:2b UP BROADCAST MULTICAST MTU:1500 Metric:1 Packets reçus:0 erreurs:0 :0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:1000 Octets reçus:0 (0.0 B) Octets transmis:0 (0.0 B) Interruption:10 Adresse de base:0xa000 Mémoire:e0206000-e0206fff lo Link encap:Boucle locale inet adr:127.0.0.1 Masque:255.0.0.0 adr inet6: ::1/128 Scope:Hôte UP LOOPBACK RUNNING MTU:16436 Metric:1 Packets reçus:116 erreurs:0 :0 overruns:0 frame:0 TX packets:116 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:0 Octets reçus:8784 (8.7 KB) Octets transmis:8784 (8.7 KB) and content of file /etc/network/interfaces is only: auto lo iface lo inet loopback Problem is not solved if i do following instructions: iwconfig eth1 essid <my network name> iwconfig eth1mode Managed iwconfig eth1 rate auto iwconfig eth1 key <myKey> Any suggestion(s)?? Thanks in advance Regards
