Internet failure
 
For the past couple of hours our internet connection has been down more than up.

Nothing in the Shub2ac log, up and down levels all fine, and all the right lights are on.

The interweb is over rated anyway. Get out, have a walk and in the Sun, and see the spring bulbs emerging :)

The BQM graph tells the story better than words

https://www.cableforum.uk/images/local/2018/02/13.png

And when a connection is there it's not 200mbps but under 10mbps. Speedtest can't even get an upload response.

Re: Internet failure
 
I would keep an eye on power levels, sounds like there is a problem with noise on the upstream.

You have a big problem there i hope they get it fixed soon for you!

It was upstream noise that used to have the same effect every time I switched the Shub 2ac on. But they sorted that when we were moved to 8DL and4 UL.

The BQM graph is starting to look like a macaw's plumage...

Re: Internet failure
 
A neighbour came to our door asking if I could fix his PC. I just did a BQM test and it was the same as mine. So he called to report the fault. "Monday fix hopefully".

His immediate neighbour saw me and said he was unable to get on Facebook. Quick BQM run, and it was the same. So he called 150. "Fixed next week".

I crossed the road and asked the owner if he was having internet problems. Yes, So I told him to call 150.

Less than an hour later the fault disappeared. Bumped up in level somewhere so that they actually decided to do something?

Taf i gave up on downloading at full speed on Virgin a long time ago without a download manager.

I bought internet download manager and get around 51mb/s at full speed and without the download manager im lucky to get 25mb/s.

yeah, the problem is that when one person rings they think the fault is just with you so they will send a tech out to fix it and they rely on him to escalate it to networks if needs be. If loads of people ring up in a short time period they pick up on it, escalate it to networks themselves and it gets fixed pronto. This is the problem I always have when my connection goes down. No matter what you say they don't want to listen to you and your just pray that other people are ringing up as well so it gets fixed asap. They don't always deal with things in the most efficient manner.

have a read of the first half of this post

As an fyi, when you set it up you cant just copy and paste the url for the graph you see in your account because it has permissions attached to it and can only be viewed when logged into your account. You need click on the share live graph button, generate, right click the graph and properties, copy the url and then insert image in this forum.

SnoopZ 20-02-2018 09:25

Re: Internet failure
 
I would say share the snap shot version, a live graph is pointless if the user wants to show something as it changes.

Taf 20-02-2018 12:14

Re: Internet failure
 
I choose Small Graph, and then copy all inside the inverted commas after src =

e.g.

src="https://www.thinkbroadband.com/broadband/monitoring/quality/share/thumb/fcbd9d74b52c9b1dbe832147fcecdb07f0cb7215-20-02-2018.png" /></a>

so you only copy

https://www.thinkbroadband.com/broad...20-02-2018.png

This gets pasted as the url to post an image to this forum.

Re: Internet failure
 
When you've generated a snapshot graph click the option to generate the code.

Then go to the bottom option for "Small Graph (500x219 px) BB code" and copy the whole thing in that box and paste it here.

It includes all the necessary BB tags to generate the graph and links here.

A snapshot graph would not show anything 'as it changes ' only what happened at a set time.

Can anybody tell me if the v6 box will still give me tv channels if the internet goes
 
Hi ,I have been told that I will still be able to get tv with the v6 box even if I lose my broadband ,is that true.

ozsat 20-02-2018 14:57

Re: Can anybody tell me if the v6 box will still give me tv channels if the internet
 
Depends on the reason for the broadband going down- but usually the tv channels will stay active although you'll loose Catch-Up and OnDemand.

That is the whole point, you dont want it to change if you're showing an issue.

Then that wouldn't be "as it changes" would it? It would be what changed & when.

Semantics I know... but.

Total network failure for our area again from late yesterday until about 20 minutes ago. I was on hold with 150 for ages, so they must have been receiving loads of calls.

Hard to do when the internet is off. :dozey:

I've been having lots of random losses of connection. They say my connection is solid, then come back and admit it's all down to "network problems".

Re: Internet failure
 
I have seen similar looking graphs when the local area has had an SNR fault..... which would be consistent with the mention of SNR fault. In my area on the few occasions this has happened they have been on it very quickly.

DOCSIS T1, T2, T3 & T4 Timeouts

This is a handy summary of the various T1, T2, T3 and T4 timeout errors you will find in a DOCSIS network. T3 and T4 timeouts are described in much more detail elsewhere in this blog, however this post provides a high level overview of the various timeouts as a reference. Thanks to baranek110 for the tutorial located on Cable-Modem's Blog.

T1 Timeout ( No UCD’s received )

Explanation: The cable modem has not received any periodic Upstream Channel Descriptor (UCD) messages from the CMTS within the timeout period. This error message is DOCSIS event message is U01.0, Upstream Channel Descriptor.

T2 Timeout ( No Maintenance Broadcasts for Ranging opportunities received )

Explanation: The cable modem did not receive a broadcast maintenance opportunity in which to transmit a Ranging Request (RNG-REQ) within the T2 timeout period (approximately 10 seconds). The cable modem is resetting its cable interface and restarting the registration process. This error message is DOCSIS event message is R01.0, Ranging Request.

T3 Timeout ( Ranging Request Retries Exhausted )

Explanation: The cable modem has sent 16 Ranging Request (RNG-REQ) messages without receiving a Ranging Response (RNG-RSP) message in reply from the CMTS. The cable modem is therefore resetting its cable interface and restarting the registration process. This typically is caused by noise on the upstream that causes the loss of MAC-layer messages. Noise could also raise the signal-to-noise ratio (SNR) on the upstream to a point where the cable modem’s power level is insufficient to transmit any messages. If the cable modem cannot raise its upstream transmit power level to a level that allows successful communication within the maximum timeout period, it resets its cable interface and restarts the registration process. This error message is DOCSIS event message is R03.0, Ranging Request.

T4 Timeout ( Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received )

Explanation: The cable modem did not received a station maintenance opportunity in which to transmit a Ranging Request (RNG-REQ) message within the T4 timeout period (30 to 35 seconds). The cable modem is resetting its cable interface and restarting the registration process. Typically, this indicates an occasional, temporary loss of service, but if the problem persists, check for possible service outages or maintenance activity on this particular headend system. This error message is DOCSIS event message is R04.0, Ranging Request.
