My stepson recently bought himself a Macbook Pro, which he has attached to our wireless network. It is, for want of a better way of expressing it, absolutely hosing our internet connection - to the extent that my Android cell can't even manage to stay connected to basic online apps when he's using it. I am almost certain it's related to the Macbook; I work remotely and I'm online all day every day, and this is only an issue when he's home and using that computer. He isn't doing anything that he wasn't before on his PC (no BitTorrent, no hardcore gaming, nothing that logically would be hosing the network or bandwidth).

I'm running a Netgear Nighthawk R7000, on firmware V1.0.5.48_1.1.79 (the router tells me that no update is available). I've set him to lowest upload priority by assigning a QoS policy to the Mac MAC, but I don't have the ability to QoS the downstream traffic. I understand that router is supposed to have dynamic downstream QoS. WMM is turned on. I'm hoping that the QoS update and turning on WMM will help some, but I'm not convinced.

I am completely Mac illiterate, but a bit of time with the Googles has informed me that this seems to be a relatively common problem related to a process called nurlsessionid. Here is what I'm considering as my next step.

Anyone else come across this and have any other insider tips?
