Internet Keeps Dropping Out with wired connection

Hi

I connect via wired ethernet to my Hub 3 and my broadband connection is intermittant.  I can be browsing then the connection drops and comes back around 30 seconds later.  It's very annoying!  I have a couple of PC's (all wired) which exhibit the same behaviour.  Of course I have reset the Hub and swapped out cables etc but nothing helps.  I'm trying to work from home but it's almost impossible.

If I log into my account and run the broadband test, it mostly shows there are no problems because the internet comes online just before I perform the test.  There are quite a few errors shown in the network log of the hub:

13/07/2020 14:01:8 critical No Ranging Response received - T3 time-out;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.0;

errors

Can anyone help?

Thanks

Re: Internet Keeps Dropping Out with wired connection

Looks like you image is rejected because it has "personal info in it.

Can you do it this way..

Copy/paste 3 FULL sets of data onto here – from the Downstream, Upstream, & Network Logs pages. Don't worry too much about the formatting it can be easily read & DON’T include personal data, i.p.'s, 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 a second time for it to send).

Also, in the meantime, (if you haven’t already) set up a free “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts - 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” when you have the first 24h period.

Re: Internet Keeps Dropping Out with wired connection

Stats look ok to me - although down channel 14 has a lot of preRS errors but seemingly all corrected (0 post errors) - I dunno if that is an indicator of an issue - hopefully someone else will comment. The BQM should be a good indicator.

Re: Internet Keeps Dropping Out with wired connection

Hi John

Here is my BQM for yesterday.  I'm not sure whether the yellow spikes indicate an issue as such [?]  We did have some dropouts yesterday but unlike the previous day, we could at least use the connection.  The dropouts lseem to last for about 10 seconds.  It feels like the VM network is overloaded, trips and then resets itself a couple of seconds later.  What do you think?

Re: Internet Keeps Dropping Out with wired connection

The BQM shows no evidence (I can see) of network disconnections - these are usually evidenced by full height vertical red bars that last for the duration of the "downtime". Ping intervals are 1 second - so anyhing of that length and above, not received back, will show. See here for explanationss

https://www.thinkbroadband.com/faq/broadband-quality-monitor

Does this time-span cover your known down times and what does the network log show at those times as well?
If its not evident in either, they are probably just wifi connection drops.
