called TekSavvy complaining about the droppouts. They sent rogers to check the lines - no issue found. I called back Teksavvy, and asked about modem swap despite warranty date passing. They send me a (free) new DCM476 modem and now problems all resolved ! My 1 year was up in august so they gave me service despite 4 months over the purchase anniversary...I'm happy with Teksavvy !!!
