Intermittent Broadband

Hi

I am getting regular, short interruptions in broadband and am getting a bit frustrated.

Sometimes the lights start flashing, sometimes they don’t.

I am concerned it is a wiring issue but I cant seem to find a way to ask someone to check wiring.

My neighbours don’t seem to have an issue and I check the status page each time but no area issues. My neighbours do have the Superhub 4 and I have the 3.

Apart from obviously visually checking, I don’t know how to check if the wiring is an issue.

If anyone can give any advice I would be really grateful!

You have a problem with downstream power levels - some are too high, and the range is too wide.  I'll mark that for staff to advise.  Usually this is a straightforward fix for the field team, although very occasionally intermittent faults can be a real pain to track down and take longer.

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!

Thanks for your post and for reaching out to the Community Forums, Tansleypete,

 

Sorry to hear that you have been having connection issues, have things improved since your post? 

Can you confirm which lights are flashing: https://www.virginmedia.com/help/virgin-media-what-do-the-lights-on-your-hub-mean

Is the hub connected to the mains or is it an extension?

 

Cheers,

You have a problem with downstream power levels - some are too high, and the range is too wide.  I'll mark that for staff to advise.  Usually this is a straightforward fix for the field team, although very occasionally intermittent faults can be a real pain to track down and take longer.

What exactly does that mean? Sorry I am not great with Broadband terminology.

Is it a physical or a software/router issue?

Hi Tansleypete,

 

Thank you for your post and welcome to the community. 

 

I'm very sorry to hear about the broadband issue you're having. 

 

I have been able to locate your account and would like to look into this. 

 

I will send you a private message to get some details.
