Now Spectrum has updated the CM3000 to version 6.01.03 - they refuse to roll it back
This darn broken firmware has made its way to Spectrum. They refuse to believe the only solution is to rollback to 5.0.X as proven method by Xfinity and other ISPs who dealt with this mess months ago...

Can you give details on what issues you have been seeing with v6 FW loaded on your CM3000?

GUI unresponsive.
Upstream light refuses to lock. Modem shows poor connection status. OFDMA channels refuse to lock.
If power cycle, sometimes all lights will lock. Modem shows good connection and shows 2 OFDMA channels are locked. However, only lasts 20-40 minutes before internet connectivity fails, even though all lights show fine. Have to power cycle to try and get connectivity back.
If power cycle several times, can get somewhat stable connectivity, but upstream light refuses to lock and OFDMA not locked and modem shows poor connection, but will hold that status for several days. Upstream/downstream speeds highly erratic.
