I first noticed my Chromecast TV was disconnected, then my 2 mobile devices and also my tablet and laptop etc.
They were all setup manually in my router settings for both 2.4Ghz and 5Ghz Primary Wireless Network connections, and both were set to Deny All Devices, unless in Wireless Filter List, and yes they have all been in my Wireless Filter List for quite some time now without any problems.
I use a strong passphrase and absolutely no one but myself has access to it in my home.
Everything was still there in the Wireless Filter List, but none of my devices would connect, I had to delete and manually reconnect them all.
I did not notice any change ion the blue lights on the router as I was not in the same room when this happened.
So I'm guessing there is no more information, or no one is bothering with looking into this?
Well its unlikely they will have any logs for that, even assuming it was the case and wasn't just a coincidence, the superhubs are known to be useless and i've had hubs randomly reboot out of the blue, i wouldn't think too much about it as its highly unlikely a member of staff would waste their personal time knock you offline for such a short period of time, they can barely take a **bleep** in a call centre without someone complaining they aren't meeting their call answering quota, i've done a similar job
It sounds a lot of bother for a disgruntled sales rep to go to for no return. Even if they did they or their accumplis would have to be tech savvy and it is unlikely they would leave an audit trail. As all is working now I suspect continuing would only waste more time than the original unwanted call.
