Started Unicast Maintenance Ranging - No Response received - T3 time-out
Hello,
My internet keeps going out every hour or 2 and it's so frustrating, this directly affects my work and personal life. It only comes back with a power cycle to the modem as well. I have a cable modem router from Motorola, the MG8702. I had a tech come out a few months ago and tighten/swap my coaxial run inside the house, but the issues persisted. I keep getting these error on my modem's logs when I check online:
Started Unicast Maintenance Ranging - No Response received - T3 time-out
Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out
Any assistance is appreciated! Here is some other info that may help (Not sure what channel 33 is, I haven't seen it on other devices):

Please create a new topic of your own here on this board detailing your issue. Thanks. The original poster has not returned. 2-month-old dead thread is now being closed.
For future reference, it is better to submit your own post as it creates a ticket to get help, and posting on someone else's older thread can delay getting help.
