Internet Intermittently Cutting Out

garetht1985
Tuning in

Having a tricky issue and looking for some help. 

Throughout the day, my internet cuts out for a minute or so before reconnecting. Seems to happen more when I’m using more bandwidth, particularly video conferencing with work. The WiFi signal remains active but I lose all connection. Happens to all devices simultaneously so can’t be the work laptop or anything like that. Happens far less frequently on evenings and weekends so at a loss on what could cause it. 

Issue started maybe 6 weeks ago but has grown more frequent ever since. Starting to impact my home working, particularly as I’m the guy who keeps disappearing from video calls!

Router is a Superhub 3 and it’s a 100mb fibre connection that was flawless up until this issue. 

All suggestions appreciated, cheers

Hi Kath,

Virgin Engineer that you arranged came in yesterday and he changed the connector (for fiber input) at the back of hub 3. 

Unfortunately intermittent cuts still continued yesterday and today. Can you help please?

Can you post your Hub status and logs again?
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).



------------------------------------------------------------------
Hub 3 - Modem Mode - TP-Link Archer C7

We've checked your connection from our side and everything appears to be within the ranges and the spec's we'd expect them to be, as lotharmat has requested, can you post the Hub stats for us please?

I'm going to send you a Private Message to get some more details from you to arrange for a technician to come out aliyanik.

 

Looking forward to hearing back from you.

 

Rob

We understand the frustration aliyanik, I have booked a technician in for you and you can find the details of the visit via your online account or here 

 

Thanks

 

Rob

Hi @James20211

Thanks for coming back to me via private message. 

I have rebooked the engineer for you now. As before, we cannot confirm the appointment time slot publicly, so to view this please sign in to My Virgin Media here: My VM

Even if the issues seem to be resolved, keep the engineer visit as the power levels won't go to where they need to be by themselves. An engineer is required to do this. 

Please let us know how the visit goes. 

Thanks,
