The SAGEM (Sagem Fast 3464) ADSL modem/router Belgacom b-box 2 is a multiservice router with a Wireless Access Point, offered by Belgacom. This modem/router is required to use the Belgacom TV services and to connect the TV decoder. If however, you have not subscribed to Belgacom TV services and you do not use a decoder, you can re-configure the router and use 4 lan ports, instead of 2. Check this post for the lay-out of the connections.
The default adress of the Access Point is http://192.168.1.1 (factory setting).
Works fine with Windows XP, Vista Home Premium and Windows 7.
