Motorola MB8600, in the list of officially approved devices
Blast Pro, 250Mbps
Connection is fine, but it locks up once evefy 24-48 hours
When it locks up, cable modem is not accessible via HTTP
Internet stops working until you reboot the modem. Modem doesn't recover on its own. Logs have many " No Ranging Response received - T3 time-out "
Have to reboot my modem once a day. Especially tough when connection goes away in the middle of important meetings
Said that I'm on Docsis 3.1 because downstream channel 32 from my modem connection page says " OFDM PLC "
Confirmed that MB8600 has a firmware bug with Docsis 3.1 which causes connection lock ups. Saying engineers are working on a fix (but no ETA)
I insisted and they shipped me a replacement modem just to rule out the hardware. It didn't help, replacement modem also has lock ups
Said I should talk to Comcast to switch me from Docsis 3.1 to Docsis 3.0, this is the only solution
Sent a technician to replace all the cables
Verified that signal levels are good +1..+3 downstream, 41..43 upstream
Sent a network supervisor for me to talk to (good conversation, but didn't yield anything)
Claims that Blast Pro boot file (d11_m_mb8600_blastpro_c01.cm) provisions customers using Docsis 3.0
They have no procedure of switching me to Doscis 3.0, as I'm already on 3.0
Won't let me speak to Tier 2 / Tier 3 teams because I own my own modem (even though it's in the list of approved devices)
So I'm stuck in the middle of Comcast and Motorola, and neither company is able to help me.
