How can it Be 5 GHz is this fast?

Recently set up new home wireless network with Spectrum-provided Arris TG1682 wireless dual-band router. Connected to an Intel NUC5 running Linux Mint 18.3 OS, using the 5G band.

As I normally do, ran Oookla Beta Speedtest, today and 2 days ago. Both tests returned 110 Mb / sec download speeds, the same speeds I was seeing on an Intel NUC5 in another room connected by network cable directly to the router. My experience over a decade with 2.4G is never seeing a wireless speed greater than 40% of the wired speed. However, thus is my first experience with 5G. My wireless sniffer program shows no competing 5G signals within 40db. I expected 5G to be faster, but nothing like this.

WPA2-AES encryption is being used. Does Speedtest somehow bypass the encryption-decode cycle ?? Browsing sites with plenty of video seems to confirm a major speed increase from what I'm used to with wireless. The Arris data sheet shows the TG1682 uses the standard 811.n, g, b, and ac protocols.

Anyone else see anything like this ??

5GHz is waaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaay faster than 2.4GHz in the majority of use cases. If you are coming from a G or N 2.4GHz only environment to a 5GHz AC environment, you without a doubt are going to see crazy levels of improvement. 2.4 is held back in speeds by the level of interference usually present as well as the newer AC standards don't apply to it.

Even if you had moved to 5GHz in the N days, you would have seen significant performance improvements. For what its worth, even back in the G days if you had an adapter that supported 'A' in 5GHz there was generally a nice boost since the airspace was generally cleaner.

Using a 2x2 AC client I can get 600mbps of real throughput when Im near my AC access point and using 80mhz channels.
