I'm having this same problem on a Dell XPS17 with the Intel Centrino Advanced 6230. I check the linked thread above that is marked as answered, but that applies to businesses with Cisco APs. I'm at home connecting to a TP-Link WR1043ND.
Same symptoms, wireless connectivity mysteriously drops every minute or so. Event ID 5060 in my logs multiple times each minute. A constant ping to my router shows frequent time-outs and high latency at times.
Driver version is 15.9.0.5 for some reason even though I installed the latest 16.1.1 installer. Windows 7 Home Premium x64 My router is using WPA2-PSK on 802.11n
