I purchase a cm100 about 8 month ago at a local store to match my Linksys wrt54g . in the last month or so I have notice sporadic internet service during which my ping time increase by ~ 500m for period of roughly 2-3 minute . well my cm100 finally die today after a gentle existence on the floor behind my tv . I be not pleased that a $ 70 modem only last 8 month .
