No Ranging Response - T3 time-out, Registration RSP Rejected, T6 Time-out

Anybody in area 26 having issues with their Virgin connection?

I keep getting examples like the below - which is making my connection unusable and I am relying on tethering to my Mobile to allow me to work uninterrupted.  As the only fix is restarting the hub which is not a quick thing so outages last 10-15 mins. 

This is my 2nd occurance of these type of issues , last April 20 was the last needed an engineer out - it was the connection into the house and at the junction box.  Whilst I had delightful run of 8 months, with the occasional issue. The last couple of weeks it is progressively getting worse.
Hardly any service yesterday, restarted my hub about 5 times  and this afternoon.

Any ideas ?

Re: No Ranging Response - T3 time-out, Registration RSP Rejected, T6 Time-out

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 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.

Down power levels are on the high side although still inside the recommended range.

The RS error counts are high so can you set them to 0 like this. 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 for the next day 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 another Tech visit will sort.

Someone more qualified needs to comment on the Logs
