Is that way popular in the UK? I think it is quite an expensive way, no?

In Belgium, plug-in line filters are the most popular, because the subscriber can easily install them without getting Belgacom in to rewire everything. A typical do-it-yourself installation takes about three days from going into the Belgacom teleboutique to pick up your line filters and sign the forms and then logging in.

The monthly cost is about EUR 30 for a 3Mbits/s service. I've been using it since about 4 years ago now, and could not bear to go back to dialup.

I am wondering about setting up a wireless network now, but at present the Alcatel Speedtouch modem feeds a NAT router/firewall (old Linux PC with a pair of NICs, one to the Speedtouch and one facing the internal 100Mbits LAN). Has worked without a hitch so far.
