Hi. Apologies if this has been covered elsewhere
For the past 5 or 6 weeks I have been suffering from an extremely annoying intermittent connection. My modem is downstairs and I am hardwired upstairs so I don't always get to see the modem, but:
The ready light on my modem stays steady
as does the ethernet and sync lights. The send receive lights seem to go blank however and it usually takes about 5 to 10 minutes for the modem to recover.
This is not good if your are using your connection through a Router as it seems to excercabate the connection issue.
I recently had my modem replaced to the 256 model but the problem remains.
My connection comes through the wall and is split into TV/Modem. I'm currently using the connection directly from the wall (not split), but it still keeps happening.
I'm having an engineer come tomorrow so I would like to be able to suggest some solutions.
My modem diagnostic/power levels seem fine:
Downstream Lock : Locked
Downstream Channel Id : 0
Downstream Frequency : 402750000 Hz
Downstream Modulation : QAM256
Downstream Symbol Rate : 5360.537 Ksym/sec
Downstream Interleave Depth : taps32Increment4
Downstream Receive Power Level : 8.0 dBmV
Downstream SNR : 39.8 dB
Upstream Lock : Locked
Upstream Channel ID : 4
Upstream Frequency : 25584000 Hz
Upstream Modulation : QPSK
Upstream Symbol Rate : 2560 Ksym/sec
Upstream transmit Power Level : 39.3 dBmV
Upstream Mini-Slot Size : 2
But my event log tells a different story:
I won't post the entire log but the main messages include:
Critical (3) Started Unicast Maintenance Ranging - No Response received -
Information (7) CableModem software upgrade failed
Notice (6) SW Download INIT - Via Config file cmreg-ntlhm250-mid.cm
Can someone help with some ideas please? This is extremely disruptive when working from home, or gaming!
Many Thanks in advance
