Virgin Media - Potential Power Level Issues?


[link to this post]
 
Afternoon all,

A bit of a weird one that I can't figure out, if any experts could lend their two cents that would be appreciated.

The past month or so, my VM Hub3 would drop connection around 2am every night on the dot. Usually it would reconnect 20-ish minutes later, but recently it doesn't reconnect at all. Fiddling around with the cable at the back, unplugging it and plugging it back in, sometimes works, sometimes doesn't.

The cable coming in from the street is split - one goes to a TiVo box, the other to the hub. I originally thought the cables or splitter were knackered after years of use, but replacing them fixed nothing.

If I plug the cable from the street directly into the hub, it works with no issues. Once the cable is split, however, the hub just won't connect any more. Worth noting that the TiVo box has zero issues when connected to the splitter.

This makes me suspect it's a power level issue that's caused when the signal is split since there is no issue when it isn't split. I don't know nearly enough about this to be certain though.

Anyone have any ideas before I call out an engineer? Currently have the hub directly connected to the cable coming in from the street, but without the splitter, the TiVo box has no signal and can't be used.

Thanks in advance for any advice.

The splitter attenuates the signal, looks like your power levels are low. You would be better to ask in the VM forum.

Who replaced the cables and splitter? If it was an VM engineer they should have checked the power levels afterwards.

Browse to the Hub's admin page at 192.168.0.1 Do not logon to the Hub at this point. There is a link "Router Status". Click on this link and you will get to the Hub information page.
The Downstream power should be between -6 and +10 and the Upstream should be between 34 to 51.
