Internet issues - slow/dropouts

Nicolleevans
Tuning in

Constant issues with our internet connection and speed. Lots of drop outs - having to disconnect and reconnect and restart.

Previous post: https://community.virginmedia.com/t5/Networking-and-WiFi/Intermittent-WiFi-where-do-I-complain-how-d...

Fobbed off with "there are issues that are being resolved once the work is finished it'll all be okay" - this has been going on since the WiFi was installed - it's a complete waste of money.

Do you have a Broadband Quality Monitor running at Thinkbroadband.com?

Have you checked for “known network faults”

As well as trying the “check service,” Area status webpage" (link at top right of this forum), 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 down to postcode level. These may not be listed on the Area Status web page (Areas are not “Geographic” they are billing areas) as that usually only covers faults affecting 1000’s of customers) so phone may give you more info, but even that wont cover problems affecting just a few customers.

See what that says.

Hi Nicolleevans,

 

Thanks for posting and sorry to see you've had some issues with the connection.

 

Have you been able to set up a BQM as jbrennand has suggested?

I think this is right?

Thats it... it looks good - apart from around 10.30am. Are there any network log messages for that time.

Also can you do this to reset the RS errors.

Switch the Hub off and unplug it for a few minutes and then start up. When done, check back in the settings and ensure that the RS error counts have all reset to 0. Then check every hour or two to see if they start reappearing - they shouldn't. If they do (particularly the postRS ones) you have a problem (noise) that only a Tech visit will sort.

It's weird because I've had to turn WiFi off on my phone to access the Internet in the last hour 🤷‍♀️

I have to restart the hub regularly and it always starts dropping out again.

At 11.30am this morning it kept kicking me out of my zoom meeting on the laptop.

Hi Nicolleevans, thanks for getting in touch.

 

Sorry to hear about the internet issues you've experienced since your installation. I've taken a look from here and everything appears to be OK to be honest, There are no signs of SNR or congestion - and all power-levels appear to be within spec as well. 

 

The logs above show a few more errors than we'd like to see ideally - however the most recent one is from the 30th, and I can see it's been more than a couple of weeks since the hub was rebooted.

 

If there's been issues in your area recently (which it looks like there has been) then your hub could definitely benefit from a reboot/fresh connection as advised above. 

If you continue to experience issues from there please keep us posted with updated hub data so we can see if errors continue to build up.

 

Tom 

 

 

I've now missed two online meeting because the WiFi is not capable of hosting the meeting without continual drop outs. 

I appreciate it might not have been restarted in the most recent weeks but historically restarting it is NOT solving the issues we are having.

Ive taken the hard cable out of the virgin media box and I am able to use the Internet without the drop outs.

What can I do about the WiFi considering there is only one product plugged in with the hard cable and its not possible to plug everything else in directly to the router. 

Thank you for the update @Nicolleevans.

 

Reboots can sometimes clear hub errors and in this case may resolve the issue you are facing. Please try rebooting the hub and let us know if the problem persists.

 

If so, we can look into further steps such as a technician visit.

 

Thanks,
