Constant outages

[Walmo21]

For the last couple of weeks I’ve been getting constant outages initially one or twice a day but this week 4 or 5 times a day 

Hub 3.0 is in modem mode and the network log has been showing t3 no ranging  responses. Today though I’ve had my first t4 ‘no maintenance opportunities received.’ 

I’ve checked the cables and they’re fine so this seems like a virgin issue not an issue my end.

Can you help.

First thing is to check for any “known network faults in your location - Look in 2 places

1) Try the “check service,”Area status webpage (https://www.virginmedia.com/help/service-status)

2) Then also Try the “free & automated” Service Status number - 0800 561 0061 - which usually gives the most up to date info. and tells you of more local issues and fix estimates, down to street cab/ postcode level.

Thanks I checked there are no issues reported.

Looked at network stats. Power levels are fine but pre/posts r’s are show lots of errors

Checked the cables but nothing seems loose or damaged. Have disconnected 6/7 times today. I reset the hub and got about 4 hours of solid connection but have had 3 disconnects in the past hour. Here are screenshots of the errors I’m getting

Cant read tables - can you do this....

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

I had already set up a BQM but my router was blocking the ping requests so will need to wait till tomorrow to see the results
