How to properly set up aliases for GIT?

Question

linux

A few days ago I switched to linux from Windows (Dist. Mint cinnamon).
It's a bit difficult to understand how it all works here ...
In short, there are two problems that I can't solve in any way:
1. I can't set up aliases to work with the git system (config and terminal on the screen).
2. Not so important, but still. After rebooting (reset) the computer, the network card stops working, more precisely, it does not see the network. After turning it off and on again, as well as after waking up from sleep, everything is fine.
Help who than can))).
Thanks in advance!

Answer 1

Aliases are configured in the [alias] block, and even better, with such a directive

git config --global alias.[alias-name] [command]

# например
git config --global alias.co checkout

I won’t tell you with a network card, google
