Re: No Ranging Response; Frequent Drop outs; RCS Partial Service

Hi thebands,

 

Thanks for posting on the Communtiy Forums! Many apologies for our delayed response from here and for the broadband issues you've been facing.

 

I've been able to locate your account from here and nothing appears to be wrong with your hub specs - everything appears to be normal on this end. How have things been since you last posted? The last graph looks quite normal, so I'm hoping that was the most recent data!

 

If you are still having issues just let us know and we'll be happy to help further.

 

Beth

Re: No Ranging Response; Frequent Drop outs; RCS Partial Service

Sorry for not replying earlier, been away on holiday.

The issue is that several times a day I will suffer a complete loss of WiFi affecting all devices including laptops, Alexa, Ring video doorbell, at locations all over the house. The ring doorbell is less than 10 feet away from the router. I do not have any wired devices capable of checking QoS.

When the loss occurs it is not just a drop in signal strength but a complete loss of signal with the SSID disappearing from the list of available networks. 

The Hub has been reset to factory settings (pinhole reset) and has been rebooted numerous times over recent weeks.

If the power ratios are OK and no one sees an issue in the monitor logs then I can only conclude this is a problem with the router (Hub3) but not sure how I can prove there is an issue? As I am working from home full time then this is very aggravating and disrupting.

Re: No Ranging Response; Frequent Drop outs; RCS Partial Service

Are the issues only evident on wifi connections or do you see them at the same times on devices connected on ethernet cables? If you don't know, can you check to help diagnose whether it is just a wifi issue or it could be network connection related?

What are the various Hub lights showing/doing when this happens?

If we are convinced that it is only a wifi issue and the network turns out to be fine, then on a Hub3, you can try separating the SSID's of the 2.4 and 5 GHz wifi bands by renaming them in the settings and at the same time switch off "channel optimisation" apply and save the settings. All wifi devices will need reconnecting to the best SSID at each location. Also use a wifi scanning App to find the best wifi channels to use (just select and use channels 1,6,11 on 2.4GHz) - this often helps Hub3 users get better wifi performance - but its still no substitute for getting better kit 🙂

To address the wifi, VM now supply “wifi Pods” (not “boosters”). Pods are free to 1GB or Ultimate Ooomph package customers others will be charged £5/month. If they are free they are well worth getting and offer a simple solution.  Order via the phone or a VM person will do it here.

If not, at that level of investment you would soon pay off that cost by buying a "better" wireless solution that will be yours to own and use forever and which will cure all your wifi problems.

"Pods are free to 1GB or Ultimate Ooomph package customers others will be charged £5/month"

Which is typical of Virginmedia, ignoring loyal customers who have been with them for many years and giving freebies to new customers who are likely paying less for a 1Gb connection than I am paying for 100Mb.

Not your fault I know but it annoys the hell out of me that I am expected to pay extra for a service that should be provided already.

Thanks for the advice but when I am giving VM nearly a thousand pound a year already then I'm not paying any more.

Re: No Ranging Response; Frequent Drop outs; RCS Partial Service

A few thoughts, since I think there's a range of different issues that are concerning you:

1) the network log you posted showed a frequency and type of error that indicated a faulty broadband connection, not just wireless.  That might have been an area fault affecting multiple users and could have been fixed without you knowing, but if those types of error continue, then your VM line has a connection fault, and VM need to send out a technician to fix it.  If VM staff are insisting that there's nothing visible from their end you may need to be persistent.  Avoid using the crap offshore telephone support at all costs, stick with the forum.

2) Getting the connection fault fixed may still not resolve the wifi - VM hubs are adequate for the most undemanding use, they're not really up to anything approaching a "connected home".  You might not want to pay VM more (and rightly so in my view) but that doesn't get away from a possible need to invest in your own wifi equipment, as many of the rest of us have done.  Here's my experience.

3) If you're paying top whack for a 100 Mbps deal, then presumably you're not getting a discount and not in a fixed term contract?  Are you playing the game?

Re: No Ranging Response; Frequent Drop outs; RCS Partial Service

NB. I have already tried using a TP-Link Archer C50 AC1200 with the VM hub in modem mode but the WiFi performance was even more disappointing than the VM Hub itself and wouldn't reach parts of the house that the VM hub does. House is a typical 3 bed semi with a loft conversion.

Re: No Ranging Response; Frequent Drop outs; RCS Partial Service

Hi there @thebands

 

Thank you so much for keeping us updated. I have rechecked your Hub specs and it does appear a few issues are now showing, for this reason I think it would be best if we got an engineer out to your property to investigate the equipment fully. 

 

I will now send you a PM so we can get this arranged. Please keep an eye out for the purple envelope in the top right corner of your screen alerting you to a new message.

 

Thank you.
