Weak Signal/Intermittent Connectivity

Hi there,

Just posting to see if anyone could help me with a Wi-Fi issue that I've been having. Specifically I've been having an issue with a weak connection in one room of the house specifically and intermittent connectivity in multiple spots throughout the house.

The signal range seems to have dropped somehow as I used to be able to get a clean signal outside in the back garden, never mind in these spots.

Downstream:

Re: Weak Signal/Intermittent Connectivity

Your up power levels are all low - normally above 35dBmV is recommended. these may be ok but it needs a VM person to look with their "tools".

One should be here in a day or so - or try calling in and see what they say about it.

In the meantime post the two missing sets of data - down table of RS errors and up table of T disconnects

Re: Weak Signal/Intermittent Connectivity

If it's only a wireless problem, then those hub status figures aren't relevant - they report only on the performance of the connection between the hub and VM's coax network.  I do observe that the upstream power is rather low (unless this is a newer VM roll out that uses fibre rather than coax) but that wouldn't have any bearing on wifi performance.

Realistically, if this is just about wifi performance, you've got four broad options:

1) Tolerate the mediocre wifi, and maybe try tinkering with the hub's settings in the hope you can eek out a bit more performance

2) Change ISP if you're outside of a minimum term contract, and make sure the next ISP has a well regarded hub

3) Use VM's wifi pods - free to customers on Ultimate Oomph and then well worth trying (though stingily handed out).  Or if you don't get them free you can rent them, at a costly £5 a month each.

4) Put the hub in modem mode and buy your own wifi gear.  That's what I've done.

In terms of why it appears to have changed, who knows?  VM update the hub firmware from time to time, sometimes that fixes or improves things, sometimes it introduces new faults, but there's a range of other potential causes, such as competing wifi signals.

Re: Weak Signal/Intermittent Connectivity

Good afternoon @Kopper 

 

Welcome to the forums and thank you for taking the time to post. 

 

I am sorry to hear that you have had some issues with your services. 

 

Are you able to confirm if its just your WiFi you are having issues with. 

 

Kind regards,

Zak_M

Re: Weak Signal/Intermittent Connectivity

As far as I can tell it is just the Wi-Fi that is experiencing issues. Performance is just fine over a wired connection.

It also does not seem to be an area based issue, as whenever I check service status using Virgin's site I never encounter any issues. Nor have I ever heard neighbours complaining about the service.

Re: Weak Signal/Intermittent Connectivity

Hi Kopper,

 

Thank you for coming back to us, I have had a look at things our end and although I cannot see any major issues I can see some of your devices do have a low WIFI signal which may be the reason you are losing connection.

 

Because of the package you are on you may be eligible for our new Intelligent WIFI Pods which will improve your WIFI connection in your property.

 

So I can help further with this I will send you a invite into a private chat, please click on the purple envelope to accept.

 

 

 

Kind regards

 

Paul.
