I have the MP6,1 12-core/1TB SSD/D700s/64GB RAM model. It does have Wi-Fi hardware 802.11ac. It has 3 displays... 60" Sony TV, LG 21:9 34" and 23" ACD. The MP6,1 is placed next to one side of a 60" Sony TV (not powered up) and has a speaker within 12 " of it. The other 2 displays are off to the other side of the MP6,1. The Internet is accessed via a 2TB Time Capsule (dual band 802.11n). This device is about 3 feet above the MP6,1. I find that at times (frequently) the MP6,1 will not connect to my Wi-Fi network be it the 2.4GHz on Chan 9 nor the 5GHz one. I have a MP5,1 with Wi-Fi which is located some 12 feet away from the same Time Capsule yet it never has issues finding the Wi-Fi network. Could the speaker close to the MP6,1 be such an influence I wonder ? Regardless, I would expect that the Time Capsule being just 3 feet away from the MP6,1 will ensure a strong signal and that the speaker should not be causing any issue.
