For information, my exchange was Broadband enabled in 2003. In 2004 I followed with a new computer, windoze XP and a D-link router/modem/radio LAN. It only had WEP security and I didn't manage to even enable that for quite a few years but it has been working H24 since then. About 6 months ago, my wife acquired a Win 7 computer. My ancient D-Link router interfaced with it immediately and continues to work perfectly.
P.P.
