does not work, then you may need to configure the network manually:
sudo service network-manager restart
after you are connected you can download dhcpcd:
sudo ifconfig eth0 your_ip_addr
sudo route add default gw router_ip_addr
echo "nameserver dns_ip_addr | sudo tee -a /etc/resolv.conf"
sudo apt-get install dhcpcd
sudo dhcpcd eth0
looking forward to your writeup
I'm taking notes for a guide writeup.
