ONU: Why it is not lit?

Thu, 18 Jul 2024 11:26:05 -0700

Why It is doing its job by giving access to an internet connection (good download speed,and very slow upload speed) despite that its light(power , PON , LAN,LOS...) are all off?I tried trning it on and off and it is still the same.

Cable Modem: Motorola MB8600 Only has a light on the bottom (Ethernet)

Sun, 29 Mar 2026 05:20:53 -0700

I have so far rebooted and reset in all ways that I could.

I am able to log into the admin console it gives me the following errors:

CMSTATUS:US_ Diplexer_Mode_Change:Fixed lnitial, 5-42MHz.

SYNC-Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing(MAC Address Here):M-OOS=1.1:CM-VER=3.1

Trying to see if this is in fact something that I can fix or if it's not worth my time -- either way I appreciate anyone's input
