I do find it strange that if my hub reports critical connection problems then surely the device it connects to must also have a similar network logs. If CS agent was made aware of the occurrence of critical errors (beyond an occurrence repeat threshold) then they could respond more effectively to customer calls. Currently the approach is analogous to asking someone if their pc has a blue screen right now, and not look at the frequency of previous blue screens. Proactively resolving issues in the "last mile", I understand is a huge task but ignoring the opportunities of visualising the data when needed could bring real value to end users and to VM's customer service Re: 16 Consecutive T3 Timeouts Causing Internet Blips - another thread Update on my issue. After a visit by VM tech who said he swapped the connection port on the street cabinet and checked signals which originally were bad and we're now good. The tech knew his stuff, understood the problem and followed up with a call 3 days later to check. The BQM and network logs are clean since a few hours after the change. Kudos to the tech and VM, just a pity it took a complaint to get things done.

I have a similar problem and have my first engineer visit scheduled for 28th July. I have tried three times via the CS, hard reset the hub, replaced in-house cables where I can, and even got a WiFi Pod for my CS efforts (go figure that waste of money - I have not even taken the device out of the box). But I have raised a formal complaint, BQM and Network Log errors correlate - here is the BQM graph Thanks for communicating your frustrations.
