I have a dell optiplex 9010 desktop PC. I have just installed ubuntu 18.04, alongside windows 10, on my hard disc in a separate partition. All is ok except I cannot establish an internet connection. When I go onto settings> Wi-fi.....it says no wifi adapter found. I have tried running an ethernet cable from laptop to desktop but it will not establish a connection. I then tried tethering my mobile phone and this allowed me to go online however I still cant figure out how to install the drivers!!

Using my laptop (packard bell) I have looked online for the drivers for these devices only because I am assuming the device drivers are not present, I downloaded from an intel web site what I think are the related drivers. The name on the file to be extracted was e1000e-3.8.4.tar.gz. I have extracted these files to a usb stick but have no idea if 1) This is the probable fix and 2) if it is how can I upload these drivers to my desktop. (my desktop is an optiplex 9010)

I am very new to linux and following some suggestions online I used the terminal command 'lspci' and this showed the following what I believe to be wifi/ethernet related devices on the system:

  1. ethernet controller [0200]:intel corp 82579LM gigabit network connection. Subsystem: Dell 82579LM gigabit network connection. Kernel driver in use: e1000e. Kernel modules: e1000e
  2. ethernet controller [0200]:intel corp 82572EI gigabit ethernet controller. Subsystem: intel corp PRO/1000PT server adapter [8086:1082] Kernel driver in use: e1000e. Kernel modules: e1000e

I have two ethernet cards in my desktop.

  1. Intel PRO/1000PT server adapter 82572EI and...
  2. Intel 82579LM gigabit network connection...

Any help would be very much appreciated. Thanks in advance.

  • The e1000e module is provided with the standard repositories. Ensure your Dell firmware is up to date and look for "missing firmware" messages: dmesg |egrep -i "fw|firm"

  • Thank you for your response. I will check online how I can tell if the firmware is up to date or not. If honest I dont understand what 'standard respositories stand for/what they are but it has given me something to look into.

  • I have not noticed any messages that relate to 'missing firmware' ...but I will look for them. When would these message likely occur?

  • At power-on, the missing firmware messages wouild show up with in a few seconds. The e1000e module is present on my 20.04 Ubuntu, and I don't even have that hardware, so I doubt it's missing on your system.
