Hello,
I'm having the same issue with my Wireless-AC 3160 adapter. I've been reading it's due to some incompatibility issues between the WLAN adapter and TP LINK routers (mine is an N600), but I still can't figure a way to fix the problem. Did you somehow manage to solve it?
I've been playing around with several drivers and configurations. As of now, the one that best works for me is:
Driver version: 7.1.0.19 (which I believe is the latest one)
Advanced configuration (Control Panel > Network and Internet > Network Connections > [Right click on Wi-Fi] > Properties > Configure > Advanced):
Wireless Mode: 802.11b/g (in order to disable AC protocol)
HT Mode: HT Mode (same as above)
Ad Hoc QoS Mode: VMM Disabled
U-APSD: Disabled
With this, I get spikes less often and they last shorter, plus increase in response time isn't bigger than 500% (at very maximum), whereas with the default configuration it was getting over 1000%. It'd be good if you could give me a hand getting rid of the spikes at all.
