Hi
First timer, not sure if this is the correct Forum
I’m beginning to suspect my 4-year-old cable modem is going South, but not sure??
Front panel LEDs seem to be OK?
Data LED blinks rapidly (as expected) when connection is established & data transfer is in progress
When disconnection happens Data LED blinks slowly & only occasionally
Disconnection happens on home desktop & laptop computers both running Windows XP SP2 Pro
Apart from replacing modem, does anyone know if there is a definite check to determine if cable modem is OK?
Understand some of the 192.168.100.1 information but there is no help file to explain if values are within acceptable limits or any explanation/meaning of Log entries?
Recurring Log entries were: (I’m only guessing what they mean)
Error ToD request sent - No Response received
Log entries never reflect true date or time so assume ToD means time-of-day
Critical Started Unicast Maintenance Ranging - No Response received - T3 time-out
This entry may be the one that causes disconnection, assume number of T3 entries has a upper limit
Information Got a map with the new UCD change count, and changed upstream parms
Twice tried start frequency reset to 339000000 Hz
First time with Router connected – nothing changed
Second time with Modem only – reboot Log entry indicated Locked Frequency = 331000000 Hz
The Downstream Frequency changed down from 331250000 Hz to 331000000 Hz
This appeared to clear the critical entry
Now with either Modem only or Modem + Router connection, the only recurring Log entry is ToD error (appears once every 2.5 minutes)
Not sure if there’s an upper limit for this error before disconnection occurs & assume the Modem gets ToD from a Virgin Media network service server?
It’s either a failing modem or could be a Virgin Media cable broadband network service problem
Does anyone have any ideas, meanwhile thanks for any help?
