Ranging Response T3 and Partial Service

Hi,

We have been having connection drops pretty much every day. Looking at the network logs I can see a number of ‘no ranging response’ and ‘RCS partial service’ error messages:

Looking at other forums it’s said that these relate to issues between the router and the box on the street. 

Has anyone else had this recently? How easy was it to get sorted by VM?

Thanks

Re: Ranging Response T3 and Partial Service

Check with Area faults on  0800 561 0061 or if you have a VM landline 150

Also please post your up/downstream stats.

Re: Ranging Response T3 and Partial Service

Thanks for your post on our Community Forums @Rruk21, and a very warm welcome to you!

Are you able to post the stats of the hub up for us, as per @Tutor's request?

Have you been able to check the local area for any faults?

Kindest regards,

Re: Ranging Response T3 and Partial Service

One upstream is on 16 QAM when it’s should be on 64 QAM and one downstream is near the minimum as well as there being a too wide a spread of power level. Also could you post the Pre & Post RS errors and the upstream t1/t2/t3/T4 counts. I think you will need a technician’s visit to rectify.

Re: Ranging Response T3 and Partial Service

Hello @Rruk21,

 

Welcome to the community, thanks for posting.

 

I am sorry for your current internet issues.

 

I was unable to locate your account using your forums details, can you tell me if you have tried doing a pin hole reset?

 

Many thanks,

Hayley

Re: Ranging Response T3 and Partial Service

Hi Hayley_S,

I am staying at my in-laws so it is their connection. I posted on here on their behalf. 

I believe they have done that reset a few times.

Re: Ranging Response T3 and Partial Service

Hi @Rruk21,

Thank you for coming back to me over Private Message. I was able to book in a technician appointment to look over your power level issues.

You can manage your appointment via your online account if needed. 

Please keep the thread updated on how you get on with your visit. 🙂

Thank you.
