Make a Wifi Access point

Wifi Access point

To make a Wifi Access Point you will need to have a working uplink connection. The connman will share that connection on the wifi.

In connman terms this is call tethering the wifi. As written in the Introduction connman creates a bridge and connects all tethered interfaces to that bridge and then runs a DHCP server on the bridge interface.

Note: This means all the tethered interfaces form a single network. As there is a DHCP server running on this network, alle devices that connect are automatically assigned an ethernet address.

All the non-tethered interfaces are uplink connections. All traffic from the bridge will be routed to the uplink connections.

Warning: The tethered interfaces are all the interfaces of a certain technology. If you have 2 wifi adapters, tethering wifi will connect both wifi interfaces on the bridge, creating 2 wifi AP’s. This is probably not what you wanted to do.

Steps:

Make sure you have a working uplink: use the services command in connmanctl. * indicates a verified uplink connection.
```
connmanctl> services 
*AR Wired      ethernet_xxxxx_cable
SomeWifi   wifi_xxxx_managed_psk
```

Make sure the wifi technology is enabled: use the technologies command in connmanctl.

connmanctl> technologies
