Not having been inside my machine in over a year, I went into panic mode when I failed to log in online. Through trial and error I made a judgement call that the modem had failed-for what ever reason. Not being willing to take the time to diagnose why it had failed (remember panic mode?) I just ordered up a new one! Two day shipping - hurry, hurry! No net-no life! Two days of pacing my living room later, It arrived and I hooked it up-closed my eyes and booted up- NO NET!!!! Oh God don't do this! Re-configure the modem? forgot that little detail. needless to say,running smooth now. Was sweating bullets for a while though over something so simple!
