I have recently changed my ISP to BT, and I use a BT-supplied router and ADSL connection.
I have two computers; one is a desktop PC, with a wired connection to the router, the other is a laptop with a wireless connection. Almost all the computing I do is on the PC, with the laptop acting purely as a backup if the PC fails in some way. It sits in a cupboard, coming out once a month for re-charging, updating software etc.
When I connect the laptop to the modem, three connection options come up in the little window, whereas with my previous ISP I only had one. The two extras that I don't recognise are BTWifi-X and BTWifi-with-FON. A bit of browsing tells me that these are for connecting to Wifi networks away from home. The security on the BTWifi-X is WPA2, as is the connection to my own modem, but the BTWifi-with-FON connection is unsecured, i.e. open. As I have never used these two facilities, and am unlikely to do so in the future (but you never know...), should I be worried about the unsecured FON connection, bearing in mind that we're always being urged to make sure our modems and other equipment are secure to prevent others hacking in to them. If I do need to make it secure, how do I do this? Is it simply a matter of accessing the modem and setting a password for FON, in the normal way, or is it within the computer itself, or doesn't FON need password protection?
