I am running windows XP SP3 using a Sagem ADSL modem.I now wish to run with a wireless Speedtouch DSL and eventually network a laptop.
My problem starts when I try to load the software for the router.A popup box tells me the software is not compatible with SP3 and I am led to believe that once you download SP3
You cannot remove it!
Any help would be appreciated.

Why even bother. Most modems have a web-based interface. Use it. The only real reson you need the "software" is if your using the USB port.

Just copy the settings. VPI and VCI are the most important.
