My DSL slowed to a crawl last week (average speed 0.5 Mb/s). I contacted CenturyLink technical support but they were unable to improve my speed. On a whim, I swapped out my new Actiontec M1000 modem for my old Actiontec GT701 modem and my speeds came back up to 7 Mb/s. Is the slow speed with the M1000 likely the result of a reconfigured CenturyLink DSLAM with which my M1000 failed to properly connect? Or, is it time to toss my M1000 in the trash?
