I have an ADSL2+ broadband connection via Telecom feeding a D-Link modem/router and then several computers around the house accessing this service via ethernet cable or wireless.
I conduct financial instrument trading from home, so a reliable connection is critical. Before Xmas I bought a Telecom broadband USB modem to contect to their cellphone network.
How do I set my computer (ie just my computer - not all the household) up so that if I lose my LAN connection and/or the ADSL feed the USB modem will automatically connect to Telecom's cellphone network. This needs to be done in a manner that means the USB modem is not using any data when not activated.
The easiest option and quickest would be to just plug it in your PC and connect to the mobile broadband when your ADSL goes down. You can't really automate it - well, not easily without custom building software.
