Random drop outs lots of T3 timeouts

verved1
Tuning in

Been suffering with some random dropouts and decided to have look at the SH4 logs and found a lot of T3 timeouts a small sample I’ve copied in.

Hoping someone from VM tech support can contact me.

Thanks.

Lets see the rest of the data...
___________________________

Navigate to these “data pages” and just copy/paste the normal “Formatted Text” (not images) 3 FULL sets of data onto here – 2 tables from the Downstream, 2 from the Upstream, & the Network Logs page again.

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). If character limits are “exceeded” - just do two posts
____________________________________________________________
Also, If you haven’t already, set up a free, secure and “offlsite” - “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “share live graph”. Click the lower link (Share Live Graph) then, click generate. Copy the text in the Direct Link box, beware, there may be more text than you can see. On here click the Link icon (2 links chain to the left of the camera icon) In the URL box paste the link you copied and then click OK

Something a bit wrong with the downstream power level on 3.1, it’s -10.8 which is out of spec and way different to the 3.0 downstream channels power levels. Wait for a VM staff member to get to your post.

Thanks for your post @verved1, and I'm sorry to hear of the issues you've been experiencing on the connection.

Looks like we'll need to get an engineer out to you on this occasion.

Please check out the purple envelope in the top right hand corner for a private message from me.

Kindest regards,

David_Bn

Thanks for coming back to me over private message @verved1, I've been able to book in an engineer appointment for you. 

For details of the time and date of the appointment, and if you need to change or cancel your appointment you can do this online or via the MyVM app by 4pm the day before the appointment.

Furthermore, I'd need to advise that;

There will be no charge for this visit unless:

  • The technician diagnoses the faults as not being caused by our network/equipment
  • The technician discovers that the fault or problem relates to your equipment
  • The technician discovers that the fault or problem relates to any system that we are not responsible for

The technician will confirm during their visit if any of these instances apply, and if so, a £25 charge will be applied to your account.

If you do miss an agreed appointment for any reason, a £25 missed appointment charge will be applied to your account on the day of the appointment.

Please ensure there is someone over the age of 18 present at the time of the visit.

We will continue to monitor your services and if we can see that the fault has cleared and the visit is no longer required we will cancel the appointment and let you know by text and email.

Kindest regards,
