Network cards on 15.04 not working - no internet access

[sam135]

I decided to install Ubuntu for the first time on a new computer, and upon booting up the live session, the ethernet would not establish a connection. I still went through with the install and the same thing continued to happen after booting into the fresh install. Decided to go out and buy a wireless network card and I can detect my network with it, but when I try to connect it attempts to do so for a short time then tells me I am offline. So no internet access through Ethernet or WiFi. I am a noob, but am willing to do whatever it takes to fix this issue. Also Ethernet worked perfect on windows. My wireless card is "Ralink RT5390". Ethernet controller is "Realtek RT8111/8168/8411". I just would like one of these to work, Ethernet perferebly. Thanks in advance.

Hi,

download these files and save them in "Downloads":

http://media-cdn.ubuntu-de.org/forum....039.00.tar.gz

http://de.archive.ubuntu.com/ubuntu/...buntu3_all.deb

Installation:

cd ~/Downloads/
sudo tar xvf 3005217-r8168-dkms-8.039.00.tar.gz -C /usr/src
sudo dkms add -m r8168-dkms -v 8.039.00
sudo dkms build -m r8168-dkms -v 8.039.00
sudo dkms install -m r8168-dkms -v 8.039.00
sudo depmod -a
sudo update-initramfs -u 
echo "blacklist r8169" | sudo tee -a /etc/modprobe.d/blacklist.conf

Reboot. LAN should work. Now run the wireless-script from the sticky-thread and show the outputs.
