Title says it all. The internet has been going out constantly everyday for over a year now. Almost all lines have been replaced as well as any type of splitter. A new router (Netgear n600 WNDR3700) as well as a new modem (Motorola Surfboard Sb6141). The modem will go out and will receive packets, but will refuse to send packets (so basically the "on" button lights up, the second light below lights up, but the third remains blinking indefinitely). I would really appreciate if ANYONE has any sort of idea of what this could be. We have had a Comcast tech guy out here once before and nothing was fixed from his "changes". We have also considered any type of overheating scenario, but that seems to not be the case.
Thank you so much. If any more information is needed please let me know!
