connman is a lightweight nework manager.

You can connect to wifi APs through its CLI with connmanctl. The steps are usually as follows:

1. Enable Wi-Fi: hardware switch or enable wifi
2. Scan for APs: scan wifi
3. List found APs: services
4. Enable auth agent: agent on
5. Connect to AP: connect <id>

DNS is managed automatically by connman through its internal DNS proxy.

Connect to a new wired ethernet interface (regular, android hotspot, etc)

Configure manually under /var/lib/connman/ethernet_XXXXXXX_cable/settings Template for DHCP, should work most of the time

[ethernet_8a0d2241dceb_cable]
Name=Wired
AutoConnect=true
Modified=2026-06-03T02:01:24Z
IPv4.method=dhcp
IPv4.DHCP.LastAddress=
IPv6.method=auto
IPv6.privacy=disabled

Restart connman and voila
