The SMC support page has diagnostic tools (under downloads) and info.
http://www.smc.com/index.cfm?event=support&localeCode=EN_USATo rebuild the network stack (software) go to control panel and delete all network connections, then reinstall them as described here
http://support.microsoft.com/kb/308522/ Obviously it's best to be sure to check and remember (write down!) any settings and gather any info, discs, drivers BEFORE you start this process.
You also didn't say if you have a router, and or the modem brand/model#.
there are a number of other things that can cause DSL disconnects (most under the control of the phone company and your ISP), so dialing up tech support wouldn't hurt either.
