Broadband connection dropping

[h5pdk]

I have been having connection issues with my broadband now for sometime. This is also affecting both my 360 TV boxes so I'm am unable to watch recordings or catch up TV etc. 

The broadband will work fine and then suddenly go off by its own accord, sometimes freezing and then sometimes losing connection altogether. When this happens if I disconnect my device I am using from the Internet it comes back on for a short time then the connection fails again. 

I have tried rebooting the router but this does not seem to have helped with the issue. The connection is being lost on both wired PC's and wireless devices in the home. All the wiring is fine and the connections on all cables are secure and  tight.

I would appreciate it if a Virginmedia moderator could get in touch with me as things have got that bad I'm having to use my phones 4g connection.

Hello h5pdk

Sorry to hear of the broadband connection issues and the inconvenience this is causing you, we appreciate you taking the time to contact us via the forums to make us aware.

I've arranged for a technician to attend tomorrow between 8am and 12pm, please let me know if there are any individuals shielding or if the appointment isn't convenient for you.

Thanks

Rob

Morning Rob, I had the tech guy out yesterday. He changed my hub plus another box and some wiring but unfortunately the fault is still there. Please advise on what to do next

Can you post your Hub status and logs?
Someone should be spot if there is a problem
Navigate to http://192.168.0.1 (or http://192.168.100.1 - if in modem mode)
Don't log in!
Click on 'router status'
Copy/paste the data from each of the tabs. The forum software will remove the MAC addresses for you (you may need to click the 'post' button again).

Also, set up a 'Broadband Quality Monitor'. This will monitor the state of your connection and record any network dropouts etc - You can do this at ThinkBroadband (https://www.thinkbroadband.com/broadband/monitoring/quality)
Give it a while to gather data and then click 'Share Live graph' and paste the 'Direct Link' into the forum!

Hi h5pdk, 

Thanks for coming back and letting us know how things went with the engineer. I'm sorry that the issue is continuing for you. 

Based on the fact the Hub was changed, we can rule a faulty hub being the cause atleast. 

I have checked the connection, and all is looking well at the moment. 

I think it would be best to set up a BQM graph as mentioned above by lotharmat so we can view the continuous stats. 

Could you also connect the Hub to a pc or laptop via an ethernet cable, reboot the Hub and then run a speed test through speedtest.net and post the results here so we can look at them. 

Many thanks,

[h5pdk]

Thanks for coming back to us @h5pdk, 

I would advise just monitoring it over a couple of days, and if the speeds are still low then I would advise coming back on here and we can look through it. 

Everything does look okay for me on the account, there are no faults or outages that could be causing issues but please do keep us updated. 

Thanks 

[h5pdk]

It isn't a speed problem it is the fact that the connection fails altogether. I am monitoring the connection on think broadband and will post the results in a couple of day. 

[Sasha_W]

Oh I see, thanks for this, 

If you could just post it in a couple of days that would be fab and we will certainly look into this if you're still experiencing a lot of drop outs. 

Thanks

Upstream should be 64 QAM - Not 32 shouldn't it‽
