I live in Spain and am thinking of going for a broadband connection.
Once installed, is there any difference between having a modem or a router ( and or, a network card )as a USB modem instalation here, can work out cheaper. I have just the one computer but do realise that a modem can only serve one computer.
If you get a USB ASDL modem, you'll (almost certainly) be limited to serving your internet connection to just the one PC. The more expensive route would be to buy an ethernet modem that plugs into your network connection on a seperate PCI card or your motheboard. The advantages of this method is that should you have more than one pc in the house, you can connect the ethernet modem to a router and provide all the PCs in your house with a connection to the internet. I have an ethernet modem and wireless router which means both my PCs, my modem and Pocket PC all share am internet connection without an endless trail of wires.
The connection to the Broadband servers is also "always on" as the ethernet modem essentially deals with the connection rather than the PC. I beleive a USB modem would have to negitate the connection to the servers each time the PC is booted (a delay of about ten seconds :-))
If you don't have a network, (or indeed a network connection), go for the cheaper USB route!
