Virus scan showed nothing - as expected, I am carefully on the security side of things (Obviously not immune though)
Not tried safeboot yet but will.
As for network, am certain that's not a issue, I have no similar problem on any other device, and our network is well run and managed.
If you must know though we have:
Multipal "Boxes" for dad works, mainly switches ect, Test equipment and enviroments, we have added nas, we have a Test PC that I am hopeing to convince my dad to set up as a server to.
we also have:
5 Phones, 4 laptops, 4 Tablets, 1PC (Mine) and a Test PC for dads work. We also have a printer and the odd guest.
Nothing out of unusal tbh, I know the network is fine, my dad works with and on network's at a extremely high level, although mainly its VOIP and and stuff like that, Network we have is sound and sercure.
Conections are made via wifi,powerline,enthernet, we use all three
as said its a pc related issue I am almost sure of it.
