Can't get IP by DHCP (Wired network)

[Njoku, George O.]

I pretty much doubt it that your Ubuntu dhcp configuration is the problem....

Using network manager.....re-configure eth0 for dhcp (don't worry if it work)

[Then focus on modem] 

Check modem configurations to see if any restrictions on leases....netmast config, range config.

Also see if you can "reset to default settings" using your laptop. Not just restarting it.

I'm using motorola SB5101E, I can't find such a button here. But I can
restart it from my laptop using its interface (I've done it many
times). Also, I've tried to power it on\off, it sometimes helped me on
my PC, but not on my laptop...


1 thing - maybe it's important. When I installed ubuntu (yesterday :)
), at first my network manager gave me some addresses, not 0.0.0.0. I
didn't get the internet, but the network manager was like it was doing
something. And after that (in 1-2 hours, when I unplugged and plugged
my cable from laptop to the desktop again and then back to laptop), it
stopped working.
