New to Virgin (problems already)

[UselessCS1]

Signed up to Virgin on the 19th of June after being away from Virgin for 2 years

 been checking the router log. Seems to be some critical errors apparently. 

Can anyone tell me what it means?

Shall I post It in there?

[jbrennand]

No just see that to answer any Q's re Log Messages - so stay here

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

Hi there. Thank for posting. Sorry to hear of the broadband issues. I've done a system check today and can see you're affected by a SNR (signal to noise ratio) issue. F009929024 - this is your fault reference. The estimated fix date is the 7th July, just after 1pm. Please monitor the connection for me after this date and let me know if having issues still, will be happy to help.

Best,

Hi I'm still getting "critical" error after the 8th

critical

No Ranging Response received - T3 time-out;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.0;

[Andrew-G · Accepted solution]

A few T3 timeouts are not unusual on a cable internet connection - if you've got speed, reliability or connection quality problems then focus on those rather than the network log.   If you're seeing T3 errors multiple times in a day then that's usually a sign of a problem, but if you're only aware of the T3s because you went looking, and there's only one every two or three days then I'd ignore it.

Thanks! I haven't really had no problems so I should stop looking at the logs 🙈🤣
