Hi All!!! I'm having a little trouble. I have ubuntu 7.04 on my laptop with an ethernet modem (seen as a wired connection). I'm getting my IP by DHCP. On my win XP it is done very quickly with no trouble. But on my Ubuntu it is not . I can see the modem, I can ping and access my gateway(my modem) in firefox (so I can reset the modem from the laptop or do any settings). When I connect to my modem, in it's settings it is said that my MAC is 'Proprietary', so all seems good. Everything seems great, but after I try to connect, it says that 'You are connected to wired network', but I get almost all ip adresses equal to '<a href="http://0.0.0.0">0.0.0.0</a>' in network manager. Seems like dhcp client does something wrong maybe.... Because the gateway itself is 100% working and I get my IP normally on winXP (just plug in the cable to my PC with XP and it's working. Plug in into my laptop with ubuntu - doesn't work )... The dhcp server sends the IP addresses by the MAC addresses. The MAC address is registered by my ISP, so it must be known on the other side. My modem (which is actually my gateway, which, I believe, should give me the IP using DHCP) is Motorola Cable Modem SB5101 Here is some data, which is taken after I try to connect and get all IPs '<a href="http://0.0.0.0">0.0.0.0</a>' in network manager: $ ifconfig -a eth1 Link encap:Ethernet HWaddr 00:16:36:4D:CF:3A inet6 addr: fe80::216:36ff:fe4d:cf3a/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:5267 errors:0 dropped:0 overruns:0 frame:0 TX packets:495 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:447752 (437.2 KiB) TX bytes:69316 (67.6 KiB) Interrupt:17 eth1:avah Link encap:Ethernet HWaddr 00:16:36:4D:CF:3A inet addr:<a href="http://169.254.5.200">169.254.5.200</a> Bcast:<a href="http://169.254.255.255">169.254.255.255</a> Mask:<a href="http://255.255.0.0">255.255.0.0</a> UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:17 lo Link encap:Local Loopback inet addr:<a href="http://127.0.0.1">127.0.0.1</a> Mask:<a href="http://255.0.0.0">255.0.0.0</a> inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:171 errors:0 dropped:0 overruns:0 frame:0 TX packets:171 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:15536 (15.1 KiB) TX bytes:15536 (15.1 KiB) $ cat /etc/network/interfaces auto lo iface lo inet loopback auto eth1 iface eth1 inet dhcp auto eth2 iface eth2 inet dhcp auto ath0 iface ath0 inet dhcp auto wlan0 iface wlan0 inet dhcp iface eth0 inet dhcp address <a href="http://87.237.115.100">87.237.115.100</a> netmask <a href="http://255.0.0.0">255.0.0.0</a> gateway <a href="http://87.237.115.1">87.237.115.1</a> auto eth0 $ route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface link-local * <a href="http://255.255.0.0">255.255.0.0</a> U 0 0 0 eth1 default * <a href="http://0.0.0.0">0.0.0.0</a> U 1000 0 0 eth1
