Checking through the log, this message appears many times. I have loads of trouble with getting devices to stay connected. The wifi is dropping off all the time and we have to reconnect. I used to have no issues at all and had a really stable connection but the last 4 months have been awful. VM have been next to useless and suggested that we need boosters. I have an M600 line and this drop off happens when you are literally sitting on the router.

I have seen responses on various threads that VM can make adjustments in the cabinets. I have checked all the cables and rebooted 1000 times. The only option is to cancel my contract if this cannot be resolved

I'm not sure it's critical in itself.
I get the T3 timeout appearing regularly too and that's on a 100% fibre installation.
There has never been a dropout or speed issue.

[richardW67]

Thanks for the reply. All ii know is the connections keep dropping and i'd like an engineer to survey and test. Something has changed in the last 4 months whereas we i had a permanent connection and no dropouts

[Andrew-G]

T3 timeouts often appear as momentary disconnections, although depending what you're doing and when they occur they may not be noticed.

I'd suggest you go back to where you got the network log, find the other tabs titled Downstream and Upstream, and copy and paste all the data for each of those two.  That'll enable us to look for noise or power level faults.

[chaoshusky]

As Andrew has said, please get the information logs from your Router, usually via 192.168.0.1 in your browser, post the contents of all the tabs here so we can take a look. Could you possibly do that for us?

Kind regards,

Lee

Not sure if this is what you need but these are all the log files I can find

Thanks for you assistance

That looks like a lot of T3s

Can we start from a blank slate?

Power off your hub
Unplug it
Leave it off for about 5 minutes
Plug it back in and switch on
Wait about 5-10 mins to stabilise

repost the stats - Let's see what starts happening!

[richardW67]

Will do. Although i do this regularly in the vain hope that it will revert back to what it was 4 months

Will have to wait until family are not using otherwise i get router rage 🙂

does this help?
