Re: Hangs and general inconsistant speeds

looks ok to me (a few T3's might mean an issue) - but someone more familiar with the Hub4 needs to comment.

----------------------

In the meantime... 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” (as per instructions on the TB website) when it starts to develop.

Re: Hangs and general inconsistant speeds

On the face if it, the raw figures don’t look too bad - but then again, I’m known for regarding the values as reported by the Hub 4 as being about as reliable as the Taliban’s report on how well they respect the rights of women! Worryingly there are a lot of errors being logged which all seemed to stop on 6th when the Hub evidently just gave up on logging them - who said the Hub 4 wasn’t a superbly engineered quality product?

So, basically who knows what’s going on?

@jbrennand’s suggestion on the Think broadband Quality monitor is certainly a good one, also, assuming that you have already power cycled the hub, I’d suggest factory resetting it to see if it can’t be persuaded to start logging something useful.

The lack of data makes a proper diagnosis difficult, but I suspect you have a cable connectivity issue and will need an engineer visit to fix, we’ll need some more recent info to be able to check though.

Re: Hangs and general inconsistant speeds

A few yellow spikes are perfectly normal - what you dont want to see are blocks of red and a red "fringe" at the top of the trace. See how it develops over 24 hours.
