No Ranging Response received - T3 time-out

The download speed from my 200mb contract is 2mb. When I look at the log of the hub, I see there’s a “No Ranging Response received - T3 time-out” message, and the associated time stamp is 1 Jan 1970. Odd. Any suggestions?

Re: No Ranging Response received - T3 time-out

Post up the rest of the hub data like this.
__________________________________

Copy/paste as “Formatted Text” (not images) 3 FULL sets of data onto here – 2 pages from the Downstream, 2 from the Upstream, & the Network Logs (again) page. 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.

Also, in the meantime... If you haven’t already, set up a free and secure “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” (as per instructions on the TB website) when it starts to develop.

Re: No Ranging Response received - T3 time-out

Mmmmm... all Hub stats are fine - however the BQM is dreadful - so far. really needs 24h of data to get a proper picture but it looks ominous - it could be overutilisation in your area (too many customers connected. Which, if it is the case - is not a great place to be.

So leave it and see how it is tomorrow at this time and then we can get VM to comment.

Can you describe ti issues you are getting at what times of the day. Is it just speed fluctuations, or are there noticeable disconnections too?

In the meantime, can you 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. Also check that the internal wiring is ok with no kinking or chaffing, check that all looks good with the outside cabling and wall box.

Re: No Ranging Response received - T3 time-out

Thanks, John!

It’s stable and consistent just incredibly slow (2mb down; 0.5mb up). My experience of it has been exactly the same at all times of day since it was installed 5 days ago. 

Cables inside are new, installed by a VM engineer and look & perfect. Outside the cables are exposed (i.e. no box) and - although tightly connected - a little weathered and generally not looking great.

Re: No Ranging Response received - T3 time-out

Good afternoon @Je_Reis 

 

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

 

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

 

I have just taken a quick look over your account and can see that you spoke with someone regarding this yesterday and you have an engineer booked to come and take a look over things. 

 

If we are able to assist further then please do let us know. 

 

Kind regards,

Zak_M

Re: No Ranging Response received - T3 time-out

Hi Zak,

Thanks for looking over my account. Until now, every VM person I spoke to on the phone insisted that there’s nothing wrong with my broadband service. After five days of calling, I said my only option is to cancel my contract unless an engineer visits, because I don’t have usable broadband. Finally that did the trick.

Can you recommend anything for me to pick up with the engineer tomorrow? I’m concerned the visit won’t be helpful, and I can’t face having to phone VM again. Literally the only helpful input  I’ve received so far is from John on this forum (thanks John!!).

Re: No Ranging Response received - T3 time-out

Hi Gareth,

The engineer replaced the cables and port, but nothing helped. Then a team came to pull a replacement cable (from our flat to the cabinet on the street), but there’s a blockage, and so now it seems we’re waiting on the “blockage team”.
