Constant disconnecrions

The Hub 3 has been for a long while randomly disconnecting at peak times. It's in router mode and most devices are connected via cable.

It starts throwing a fit, Internet on off on off on off on off on off on off on off on off in a matter of 5 minutes. Ran network diagnostic and saying couldn't contact DNS which I believe is your end?

Infuriating is understatement. Seems as i want to use computer, Virgin Media says no! Not without frustration. 

Also recent speeds have been up and down at best. Ranging from 0.90Mbs to 620+mbs (that was today after doing a reset)

I'm not sure if relevant but when the extra phone line was installed recently, the cover on the box outside doesn't close. Maybe related? Could it be getting wet and messing things up?

My problem too. It is not a local problem. It is a central problem that Virginmedia seem to be incapable of fixing.

Re: Constant disconnections

It has been very slow pretty much all week now, sometimes complete disconnection.  I've messaged Virgin Media (C-051220716) as the box on wall outside house has been left exposed to the elements, which also seem to coincide with outages/dropouts, following an engineer visit to install a second phoneline (extension to existing) Updated Readings:   Downstream bonded channels

Re: Constant disconnections

Horrendous RS error counts = noise getting in. You need VM to take a look at the connection and probably a Tech visit to fix.

Try calling in at 08.00 messaging is too slow

Try this as well...

_____________________

First switch the Hub off for 5 minutes AND unplug it from the mains. Whilst it's off, do a quick check that all of your coax cable connections are in nice and "finger" tight - at the Hub and wall box and also at any connectors etc.  Ensure there are no “unterminated cable loose ends.  Disconnect all the connections and reconnect to be sure.  Also check that the internal wiring is ok with no kinking or chaffing, check that all looks good with the outside cabling and wall box.  Then switch it on again and leave 5 minutes

Then do a Hub “pinhole reset” -  but, make sure the 2 passwords on the Hub sticker are still there and legible first ! Disconnect any ethernet cables from the Hub, and then with the Hub still "switched on" throughout, press pin in firmly with paper clip/SIM tray tool or similar "thin thing" and hold it there firmly for 60 seconds – release the pin then leave the Hub 10’ to stabilise.

Also, in the meantime... if you haven’t already, set up a free and secure “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “shared graph” (as per instructions on the TB website) when you have the first 24h period.

Re: Constant disconnections

You say "Noise getting in" is it possible that it's because that outside case is off then?

The grey box on the wall of the house, the cover has come completely off. VM sent an engineer out around August to install another phone line and the guy never put the plastic back on properly. It has now since fallen off completely

Yes that's a possibility - but there are lots of others 🙂

Took onboard your advice, did a reset via hub page made little to no difference then I pulled power and left is about 20 minutes while I went outside and looked at wires hanging out of the wall!  All sorts of gunk on them, mottled cobwebs and what looks like string but most likely just crap gotten mottled up with dirt, dust and cobwebs.  Have rested the cover over top of cables to keep worst of elements off it but the way they've left them, there's no way I'm attempting to put it on properly as it would mean mashing them all up to fit inside the box!

Plugged HUB back in and so far so good.  Getting acceptable speeds now and connection seems solid at time of typing!

Thanks, J will keep posted if goes belly up again!
