Internet keeps dropping both wifi and wired

[stevemagee60]

Internet keeps dropping on both wifi and wired we probably notice it a couple of times a day but could be more.  This is the logs from the router but no idea what it means?

There's nothing in the log that really stands out (a few errors are normal, what counts is the type and frequency), but if you post the Downstream and Upstream tables that you'll find alongside the Network log then we can take a look for potential noise or power faults.

Hi Andrew, thanks so much for the reply. My wife wanted me to try something fix it this morning so I reset it to factory settings so I think that wiped the logs.as there was definitely at least T3 errors there so not sure if this will be helpful. Before I had done that the wired had been out for almost 24hrs and that did seem to fix it temporarily . I've been out today but she says so far her wired connection cut out again but wifi was then ok. I just tried to wired and seems to be working again now. 

Thanks again
Steve

Nothing really leaping out there so...
------

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

Hi stevemagee60, 

Thanks for your post and welcome to the forums. It's great having you on board with us in the Community. 

I'm sorry to hear you are having an issue with your broadband connection. 

Taking a look at you hub, all is looking good. The power levels, signal levels and uptime is all looking good. The area segment is looking good too so there is no developing area fault affecting you. 

Looking at the devices connected to the Hub, the following links will help you to optimise your network 

• Wi-Fi hints and tips
• Wi-Fi troubleshooting

In terms of the wired devices dropping too, please set up the BQM and post the live URL here so we can look in to this further for you. Keep us posted on how things go. 

Thanks, 

[stevemagee60]

Sorry I have been sick for a couple of days I will do this soon. Thank you 🙂 

[stevemagee60]

Hi John, thank you for this and apologies for replying at the time I have been sick for a few days. I haven't done that yet so I will do it now.  

Thanks again 

Steve

Hi @stevemagee60,

Hope you are feeling better?

We look forward to receiving you BQM and we can take it from there 🙂

[stevemagee60]

Hi all, I think I have followed the instruction right and this is the link to my live graph. https://www.thinkbroadband.com/broadband/monitoring/quality/share/6891460ed17a808f32cd469508b0770910... 

On Saturday it completely stopped I think I restarted the router but it didn't come back immediately. I also bought a boaster which says it's working however hasn't seemed to make any difference. I also bought one of the ones plugs in directly that goes through the powerlines just to try but even pluging driectly into the the back rarely works.  

This evening I disconnected every device in the house apart from my wifes laptop that she was working on and on the google internet speed test she was getting 0.99 Mbps download and 0.5 Mbps upload for a good while now with more devices reconnected it's 9.65 Mbps download 3.12 Mbps upload.

I'm on Virgin Media M100 Fibre Broadband if that makes  any difference.  

Many thanks for all your help and advise! 
Steve

Your BQM is fine.

We’re these Speedtest done on a wired device?

Don’t use the Google speed test either - it’s highly inaccurate.
