ubuntu/dhcp/installation problem

[D1G1T4L]

so i am installing ubuntu and it's trying to configure the network, it says "Network configuration has failed" your network is probably not using the dhcp protocol. Alternatively, the DHCP server may be slow or some network hardware is not working properly.

so it seems like ubuntu config cant detect my network, yet my router sees the ubuntu ethernet address and assigns a dynamic ip to it, how can this be?

i installed ubuntu
i am trying to connect to internet, it's not working, i have even tried another ethernet card

when i try to ping my router i get "connect: network is unreachable"

and when i do sudo dhclient eth0, i think it tries searching and then says no dhcpoffers
no working leases in persisten database-sleeping

i am looking in my /etc/network/interfaces


it says

iface eth0 inet static
network 192.168.0.0
broadcast 192.168.0.255
dns-nameservers 192.168.0.1
address 192.168.0.100
netmask 255.255.255.0
gateway 192.168.0.1

this is after i tried setting up static ip in ubuntu and my router

i have no idea where the 192.168.0.0 and 192.168.0.255 came from

what should i put for network and broadcast?



in my route -n
it shows
destination gateway genmask flags metric ref use iface
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 eth0

is your modem working? have your powered the odem and router down and restarted? go into the nic properties and reactivate the eth0 nic. should work after that.
