Repeated drop outs

Good afternoon,

We've been with Virgin since late March. Over the last month, we keep losing signal on various devices. I've checked the service status and rebooted the router and devices multiple times but the issue keeps happening.

I've set up a BQM as I saw that's what others on the forum, were doing. Here's a snapshot of today:

Is there anything I can do to improve this? Also am I more likely to get a reply on this forum than calling the general customer services line?

Thanks.

Mark

Re: Repeated drop outs

Looks bad - can you post the Hub stats as per below. A VM person will respond here in a day or so and book a Tech visit if needed - lets see the stats.

Don't worry too much about the formatting it can be easily read & DON’T include personal data or MAC addresses - blank them out - if you copy/paste the data, the board software will do this for you (you may need to click the "submit" button again.

Re: Repeated drop outs

The RS error counts may be a concern or just historical build up as may be the T3 timeouts so can you reset then as below. The BQM looks poor earlier in the day but ok since ~3pm. See how it goes but I think a VM person needs to take a look when they get here
_____________________________________________________________

Switch the Hub off and unplug it for a few minutes and then start up. Whilst it's off, do a quick check that all of your coax cable connections are in nice and "finger" tight - at the Hub and wall box and also at any connectors etc. Ensure there are no “unterminated cable loose ends. Disconnect all the connections and reconnect to be sure.

When done, check back in the settings and ensure that the RS error counts have all reset to 0. Then check every hour or so 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.

Re: Repeated drop outs

Thanks again John. I've just followed your instructions and all the Post RS Errors seem to be 0, copied below. Should the pre RS Errors be 0 or are they ok? I'll keep an eye on this over the next few hours.

Re: Repeated drop outs

You often get a few pre RS errors and they get "corrected" - if they dont they appear as post-RS errors
See how it goes

Re: Repeated drop outs

Haven't noticed any Post RS errors change from 0. However, I've still had a few drop outs this evening.

Re: Repeated drop outs

Hi holty88, 

Thanks for your post and apologies to hear you've been having an issue with repeated drop outs. 

I'm happy to take a look in to things but I've been unable to locate your account via your forum credentials. I will need to confirm some information with you in order for me to proceed with checks.

I have sent you a private message regarding this and will investigate further once I receive your reply. Just click on the little plum envelope at the top right hand side of the page to access your inbox.

 

Thanks,

Re: Repeated drop outs

Hi holty88, 

Thanks for coming back to me via private message with your details. 

Checking the account, all is looking good. Your power levels and signal levels are optimal and there are no issues in your area too. Timeouts and error logs are looking fine now too. 

Looking at your WiFi, most, if not all of your devices are connecting to the 5Ghz band. As there are so many, this may be causing the issues with the drop outs. 

Try using the devices in the area they are most used, instead of connecting them close to the Hub. Turn the device to flight or airplane mode then turn it off. This should connect to the band best for the device and should help to improve things. 

Monitor things over the next few days and let us know how you get on. 

Thanks,

Kath_F
