Ethernet devices don’t show up in “/dev
” (although CANbus can, this is different). These occur with “/sys
” exports for most cases.
Depending on software release one of these sets of commands will be of interest to you (I am excluding Wi-Fi commands in the first part of the list):
# older and my favorite:
ifconfig
route
# newer:
ip -s addr
ip route
I’m not really a Wi-Fi person, but the above will show some Wi-Fi devices (if active). Some other commands related to Wi-Fi:
rfkill
rfkill list
Someone else would have to help with wireless, but one of the things that confuses a lot of people is that Wi-Fi usually runs only from a GUI login, and is then owned by that user until they log out. Not being in the GUI, or having some detail about your login account not behave as expected, could lead to Wi-Fi also failing. You would have to provide more details about what you are doing and connecting for someone to help (and if it is Wi-Fi I can’t help).
