Power levels on Hub5
Hi guys, had an engineer visit last week and only really got a chance to test it all properly. To cut a long story short I was having intermittent issues with connection, ping, jitter etc so engineer instantly said that the signal was too high for the line. So started testing under load, and it’s probably worse than it ever was but a bit late in the week now for VM to resolve. Looking through some threads on here and couldn’t really find a “what should my power levels be” thread. picture of downstream/upstream network status, either above or below? Thanks 🙂Lots Of Timeout Errors
Hello all, I have factory reset my Hub Today, as Microsoft Teams seemed very slow and the general usage of the Internet. I have had a look at the logs and there are a lot of Timeout Errors. My Power Levels also don't seem right and this is after a pinhole factory reset (held for 60 seconds). Please can someone have a look at Virgin's end and also my errors /power levels?Latency and Packet Loss Spikes for Months, Are These Power Levels Normal?
Hey everyone, for the last few months we have been having very high packet loss and latency spikes (ranging from only a few seconds to a few hours at a time). For a quick example here is the connection today to OpenDNS. With average latency of around 900ms during the window (the graph is for 3 hours). Before and after will be okay with latency of between 10 and 21ms. Local traffic is completely fine. The box is a SuperHub 3 and has been running in Modem Mode for years. I have been trying everything and speaking to Virgin Media but as the issue is intermittent they are not interested in investigating. One final thought I have is that it might be related to power levels. I don't really know anything but I feel the T3 timeouts look a bit high. What do people think? This was also during a period of the connection working, will try and capture it during a spike next time. Also, thank you so much for any time you spent on this. It has been driving me insane.
