# Why will my WAN connection not be started?

In contrast to a local network (LAN), a WAN connection will not be started immediately. A WAN connection will then be established, if a WAN chain, which contains the respective WAN interface, is started. The status of the existing [WAN chain](https://docs.insys-icom.com/kb/docs/wan-chains-and-wan-groups-en) is displayed on the *Status* → *Dashboard* page. The following prerequisites must be met for a functional WAN connection:

- In case of an Ethernet connection, the respective IP net must be activated ( *Network* → *Interfaces →* *IP networks*)
- In case of a cellular connection, the respective modem interface must be configured correctly ( *Network* → *Interfaces →* *LTE)*
- *The WAN interface must be contained in a WAN chain (* *Network* → *WAN / Internet)*
- *If the WAN chain contains more than one interface, all must be functional that the WAN chain can be started*
- *If more than one WAN chain exists, sequential order and WAN chain to be started in case of failure are decisive*
