a relative has ATT DSL service. About 37 days ago it stopped working. many calls to India, California, Michigan. Test, OK, users problem, ATT OK, MUST BE USER. Replace phone line(pots)1500' away because open, got dial tone on, noise off, still no i-net. Replace user phone line, buy new walmart voice phone, buy new ethernet cables, buy new netgear modem/router, etc. PROBLEM WAS: ATT had changed password that goes on router / modem and didn't know it. (we had verified old password w/ ATT several times. ) friend said ATT probably changed and forgot password - did that and now everything is good, at least for the moment. 4k e-mails to read! FWIW
