Can you help me solve a couple of problems with the Mikrotik router?

Question

Computer networks

I bought the other day Mikrotik hAP AC. Connected to it at 5GHz - iPhone SE, Macbook Pro 2015 and iPad mini 2 at 2.4GHz. NAS connected via gigabit cable.
Problems:
1) iPad turns on the screen and connects to the network for 30 seconds. on the last zyxel router - it was instantaneous.
2) The speed of copying from NAS to Macbook does not exceed 400Mbps or 50Mbps. The disk system here and there is very fast. It's about the network. ipref gives out 400Mbit between computers, although the connection is at least 800Mbit, and I tried it on 1300Mbit. Maybe it's the LAN between the NAS and the router. But the card is gigabit, the cat.5e cable is definitely of high quality. I’ll make a reservation right away, 80MHz, 3x3 MIMO is enabled on Mikrotik and is supported by a macbook.

Answer 1

show the registration table at the time of the test
/interface wireless registration-table print

Answer 2

The maximum speed of a gigabit connection over a copper wire in one direction is 597 megabits (with the Jumboframe enabled + trimming some of the headers and halving the preamble). Nothing more can be expected from him. It's built into the transmission standard.
Optics is able to utilize the physical medium differently, and in / on optical gigabit you would get almost 1Gb / s in one direction (or in each direction, depending on the type of connection), but not in the case of copper. So in your case, 400 megabits to the NAS is the limit and, at the same time, an excellent indicator.
Config notes:
/interface wireless
set [ find default-name=wlan2 ]
preamble-mode= both
/interface wireless nstreme
set wlan2 comment="WiFi 5Ghz" enable-polling= yes
set wlan1 comment="WiFi 2.4Ghz" enable-polling= yes
Rebooting the device because the provider is not paid is unnecessary:
​​/system watchdog
set watch-address=8.8.8.8
For wireless network speed - try playing with the location of the device (inside not the most powerful antennas) and channels.
