No Ranging Response received - T3 time-out

Internet has been dropping out frequently and whilst it will only be for 5-10 minutes, it is unbearable especially when the alarm system begins to beep when it is not connected to the wifi.

Any advice?

Some logs below;

Re: No Ranging Response received - T3 time-out

Your downstream power levels are all very high - the recommend maximum is +10dBmV. It will need a tech visit to adjust.


Call it in on 150 (VM Phone) or 0345 454 1111 (any other phone) and see what they say when they test the connection. Calling at 08.00 midweek (09.00 Sun) is the best time to get through quickly. Although some people are still reporting getting through fine at other times with no long waits

If you get cut off after an automated reboot cycle, just call back in a couple of minutes as the system should know that you have just been on and it hasn’t helped and put you in the queue. Or try options 1,1,4,4, “thinking of leaving” - they usually pick those calls up quickly and then transfer you to the appropriate queue (or cut you off !).

You can also text them on 07533 051809 include account name/number and what the issue is – replies usually take longer.

A VM person should pick this up here and respond, but it can take a week or so for them to get here.

Re: No Ranging Response received - T3 time-out

Good afternoon @wongman 

 

Welcome to the forums and thank you for taking the time to post. 

 

I am sorry to hear that you have had some issues with your services. 

 

As advised above it dose seem as though the has been an issues with your downstream power levels. 

 

I have taken the opportunity to book an engineer for the next available appointment, you can find the time and date of your appointment via your online account. 

 

Kind regards,

Zak_M
