Once in, scan the network, add an empty place to store credentials, then input them.
> scan

> add_network
This outputs a network number, e.g. '3'. This is the new network you'll work with.

> set_network 3 psk *"Kosachok2019"*
OR (for no password)
> set_network *3* key_mgmt NONE
> enable_network 3
> save_config
This takes a while to connect, so to speed things up, restart the service:
> sudo sv restart wpa_supplicant
# Scripts
You can script like this:
> wpa_cli add_network
That returns an ID, so you can say:
> newNetwork="$(wpa_cli add_network)"
Then `$newNetwork` would equal that number, and you can add/ remove networks with scripts.
But remember to escape the quotes, so adding a network would be:
> wpa_cli set_network *3* psk *\""passphrase"\"*
