Internet intermittent

  • Hi

Hope someone can help, working from home and 2 kids home schooling 😢😢. Sometimes the Internet is fine then drops,

Are the error numbers high? What could cause this there's no issue with tv?

Re: Internet intermittent

Its hard to see from what you have posted but looks like your downstream channels are way out. Are some of them above 10 ?

Re: Internet intermittent

I have the same issue. Internet disconnecting every 2 minutes for like 20 seconds or so.

This is just classic Virgin Media. Says there is no fault in the area. But when I run a test it does say there's an issue. If you rebooted etc and checked connections there is nothing you can do but wait until Virgin fixes their stuff.

Stats ok apart from RS errors and logs look ominous.  Can you do this.....

___________________________________________________________-

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 a few minutes

Then do a Hub “pinhole reset” - 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 firmly for at least 60 seconds, release the pin, leave for 10’ to stabilise - dont manually switch it off at any time.

When done, check back in the settings and ensure that the RS error counts have all reset to 0. Then check every hour or two for the next day or two to see if they start reappearing - they shouldn't. If they do (particularly the postRS ones) you have a problem (noise) that only a Tech visit will sort.

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 “share live graph” (as per instructions on the TB website) when it starts to develop.

Re: Internet intermittent

I have the same issue just spoke to someone on the phone and they've said there is an upstream issue that's being looked at.

My connection says unsecure on my laptop which it never did before and keeps dropping on multiple devices or stop working.

Re: Internet intermittent

Thanks I'll try this tomorrow

This evening I tightened the cable joint near the street (someone set fire to our bins so we have 2 external joints) this has stopped drop outs, but still loads of errors.
