how about range, does the AC86U have better, worse, or the same Wireless range as the AC88U?
I can compare my two AC86Us (1 as router, other is an access point) to the two AC68Us they replaced. Signal strength is slightly stronger on the 5Ghz, slightly weaker on the 2.4. I get 4-5 bars on every wireless device in the house over 2 floors (about 1700 sq ft). When son is home that's 3 cell phones, 3 smart TVs, an HTPC and wife's tablet plus 2 computers, 2 NAS boxes and a color laser printer hardwired. handles all of them fine, wireless data through put is a bit faster. No benchmarks, just every day usage shows it's a bit faster.
