В доме интернет через wi-fi роутер. При установке Ubuntu успешно к нему подключилась. Далее я хотел поставить по проводной сети систему на нетбук. Для этого поставил tftp, dhcp и перенастроил вручную eth0 (проводное соединение не использовалось), потому что без этого dhcp не вставал:
sudo ifconfig eth0 192.168.0.1 netmask 255.255.255.0
После этого после отключения от wi-fi (перезагрузка) система не может к нему снова подключиться. Цитата из сислога (SSID сети - IKh):
