I am running TP-Link AP's. Two of them are Google OnHub, which was built 
by TP-Link, and the 3rd one is the TP-Link Archer C6.

So they all support 802.11ac, which is where my device spends most of 
its time (5GHz).

No interference from my neighbors (separated by thick walls), and I am 
running separate channels for both frequencies per device.

Also, no other wireless device is suffering like this.

No issues on the wire at all. Quite perfect.

Like you, I hard-wire all fixed devices (TV's, a/v receivers, satellite 
decoders, gaming consoles, energy meters, e.t.c.). The only devices on 
wireless are mobile devices, tablets, laptops and the Windows PC which 
is hooked up via wi-fi as well.

I use Viscosity as an SSL/VPN client. The issue is the same whether it 
is enabled or offline.

Mark.
