buy this modem because of how well supposedly it work with Comcast and think I could avoid the $ 7.00 rental fee every month . so after follow the ` easy ' instruction , I have no internet access , my network can not be find and there be absolutely no support . Comcast could not & would not help I because it be not there equipment . so basically I have a $ 85 paperweight . oh and it only take 2 hour to restore the network , reset the router at 1am . I work from home after hour so must be connect .
