Connection Drops “No Ranging Response Received” and “Unicast Maintenance Ranging Attempted - No response”
“I’m seeing very frequent connection drops. Daily drops, and multiple hours when the network is unavailable. This means I cannot work from home and is very frustrating, especially as it seems impossible to get any support from the call center.
Today (Wed 2020-05-27) the network connection failed. After I restarted the Hub 3.0 it claims to be on-line, but I am seeing massive levels of packet loss.
Tue 2020-05-26 the network connection was down for 3-4 hours.
Sunday 2020-05-24 the network connection failed for 1 hour then again for 2 hours
2020-05-19 the network connection failed twice
2020-05-12 the network connection failed
2020-05-08 the network connection failed
2020-05-07 the network connection failed
The Hub 3.0 model is VMDG505/TG2492LG-VM. Network Log in the Hub 3.0 shows the first error is:
“No Ranging Response Received - T3 time-out.”
Downstream power is between 0.7 and 1.5 dBmV (SNR is 38dB)
Upstream power is between 4.425 and 4.5 dBmV (SNR is not shown)
This problem has been going on for a while, but is getting significantly worse. Sadly, trying to get support from the call center is hopeless, as the default response is “switch it off and switch it on”. I have already tried that, it then takes up to an hour or more to re-connect ...
Is there any way I can raise a trouble ticket on-line, as it looks like a physical layer issue?
