Service drops multiple times a day across Wi-Fi and ethernet connections

[PhilC]

Over the last week, I have been having major issues on maintaining a stable connection to the net, I have multiple devices connected via Wi-Fi and they drop many times during the day, even devices which are located and used right next to my Hub 4.

I am also noticing connection drops on devices which are connected via Ethernet, from both being directly connected to the hub 4, and also via a Gigabit switches

We had a major service outage around a month ago, where it was down for 2 days, came back up, then when down again for a day, and was finally stable, but since then I have noticed more drops over Wi-Fi and now across ethernet connections

I have run checks on the connection, via the hub 4 interface, which says everything is working, but I have had 5 disconnections from Wi-Fi this morning and 3 from a PC directly connected to the Hub by ethernet. I have taken these devices to another location and they connect and work fine, so there seems to be an issue with my connection

I have tried to use the support/help via the My Virgin media, but the online element doesn't work, and the phone queue, I am in a long line, any ideas on how I can get this resolved, as I am paying a fortune for a service, which is not consistently working everyday now. Is the Hub on its way out?

can you do this...

_______________

Post up your Hub/network connection details in the format below and someone will check to see if there is a problem there.  In your browser’s URL type in 192.168.0.1 if in router mode or 192.168.100.1 if in modem mode. No need to log in - just click on the “Router Status” icon/text at bottom-middle (Hub3/4/5) or top/right (SH’s) - of the Login page.

Then… Navigate to these “data pages” and just copy/paste the normal “Formatted Text” (not images) 3 FULL sets of data onto here – 2 tables from the Downstream, 2 from the Upstream, & the Network Logs pages. Don't worry too much about the formatting it can be easily read & DON’T include personal data or MAC addresses - blank them out - if you copy/paste the data, the board software will do this for you (you may need to click the "submit" button again). If character limits are “exceeded” - just do two posts

Also, If you haven’t already, set up a free, secure and “offlsite” - “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”. Click the lower link (Share Live Graph) then, click generate. Copy the text in the Direct Link box, beware, there may be more text than you can see. On here click the Link icon (2 links chain to the left of the camera icon) In the URL box paste the link you copied and then click OK

[PhilC]

Thanks John, hopefully someone can read those and let me know if there is an issue, as its really frustrating having multiple intermittent connection issues, when WFH and presenting

[jbrennand]

Power levels look ok to me - also errors all fine - not sure about Down 3.1 channel as some ubcorrectables  there - someone else needs to comment on that and the logs

Also... lets see the BQM -it will be informative

[PhilC]

Its currently generating, will post it, when it has a couple of hours
