If this is the case it is worth trying to configure the [[docs:guide-user:network:wan:wwan:ethernetoverusb_ncm|NCM]] interface instead.
  
 If the modem exposes //serial// interfaces then the appropriate driver needs to be installed (''kmod-usb-serial'' or ''kmod-usb-serial-option'' or ''kmod-usb-serial-qualcomm'' or ''kmod-usb-acm'') as well as a simple //terminal// app like ''picocom''. More about: sending [[docs:guide-user:network:wan:wwan:at_commands|AT commands]] from the router. If the modem exposes //serial// interfaces then the appropriate driver needs to be installed (''kmod-usb-serial'' or ''kmod-usb-serial-option'' or ''kmod-usb-serial-qualcomm'' or ''kmod-usb-acm'') as well as a simple //terminal// app like ''picocom''.

-Since RNDIS-based sticks create their own NAT'ed IP subnet, it is important that OpenWrt's LAN IP range is different from the modem's IP range. In the case of the Alcatel L850, the default range is 192.168.1.1, which clashes with OpenWrt's default. Therefore OpenWrt's LAN IP should be changed to something else, such as: 
- 
-<code> 
-config interface 'lan' 
-        option ipaddr '192.168.10.1' 
-</code> 
-

 If auto-connect is disabled, or PIN-request is enabled on the modem, you may need to visit its admin web interface (typically at ''http://192.168.1.1'') to enter the PIN and/or initiate the connection. If auto-connect is disabled, or PIN-request is enabled on the modem, you may need to visit its admin web interface (typically at ''http://192.168.1.1'') to enter the PIN and/or initiate the connection.
