Hey guys. Saw this thread over here.
So I'm hoping that you all might be able to help me shine some light on what's going on with my modem here. It intermittently disconnects with Comcast. Tech came out and said I should try doing the whole Best Buy check and see method - but really don't want to pay for yet another modem to have this happen again. (I've had to get a couple since 2011.)
Router is a Netgear WNR834Bv2 - Haven't had too many problems with my LAN when the modem isn't functioning.
When the modem becomes unsynced with Comcast, the Online light stops flashing and simply goes straight amber:
So, as asked in other threads, here's what I've been able to round up as far as info needed:
Upstream / Downstream Levels:
Normal status:
T3/T4 Timeout (Not "Synced"):
