Trying really hard to bring an old e1505 back to life. A few days ago I installed Ubuntu 16 on it and worked fine, except it can't find any network devices. The weird thing is that it can detect the ethernet port when I boot it from the Live CD, but after installing it it couldn't find anything. However, I got it working by reinstalling the system. The Wi-Fi wasn't working, but ethernet did work. Later I managed to fix Wi-Fi with the help of this but then I did something horribly wrong with the system and I had to reinstall again, but after this reinstall it can't find any network devices.
Here's the output of ifconfig:

lo        Link encap:Local Loopback  
      inet addr:127.0.0.1  Mask:255.0.0.0

  • You can get the Ethernet temporarily working by sudo modprobe b44. Please [edit] your question and add output of lspci -knn | grep Net -A2 terminal command. – Pilot6 Sep 10 '16 at 11:50
  • sudo modprobe 44 is stuck, doesn't output anything, doesn't fix it either. edited question and added the output of lspci -knn | grep Net -A2. Sorry for the late reply. – Areg Hovhannisyan Sep 10 '16 at 12:27

You installed a wrong wireless driver that also blacklisted the Ethernet adapter. You can fix it this way.

Run

sudo apt purge bcmwl-kernel-source

Reboot.

After that the Ethernet adapter should work. Connect to the internet by wire and install firmware for your wireless adapter by

sudo apt install firmware-b43-installer
