hAP low speed

Hello,
I have a MT hAP router and I have a very big problem with wifi performance. My best speedtest result is download 15Mbit / s upload 35Mbit / s or is it the max of this device?
Very simple configuration:
wlan1 + ether1 … ether5 - bridge

wlan1 settings:
name=“wlan1” mtu=1500 l2mtu=1600 mac-address=64:D1:54:36:47:B5 arp=enabled
interface-type=Atheros AR9300 mode=ap-bridge ssid=“dom” frequency=2422
band=2ghz-b/g/n channel-width=20/40mhz-Ce secondary-channel=“”
scan-list=default wireless-protocol=802.11 vlan-mode=no-tag vlan-id=1
wds-mode=disabled wds-default-bridge=none wds-ignore-ssid=no
bridge-mode=enabled default-authentication=yes default-forwarding=yes
default-ap-tx-limit=0 default-client-tx-limit=0 hide-ssid=no
security-profile=default compression=no

Device plugged in after ether1 speed 90Mbit / s / 90Mbit / s so the problem is with wifi. The device hooked on wifi is a huaway P9 lite phone.

Post there - “wireless registration table” with visible TX/RX rate a CCQ

How “fast” is your internet (DSL, cable, fibre etc…)

If you connect a laptop / PC to one of the UTP ports (and switch off WiFi on the laptop), what speed do you get then?

Hi
CCQ - have 95-104%
signal to noise 64dB
tx/rs signal strength -54dBm
tx/rs signal strength ch0 - 63dBm
tx/rs signal strength ch1 - 55dBm

if i connect laptop to ether1,2,3,4,5 - have speed 90Mbit/s /90Mbit/s.
Problem is only whit radio.

And registration table? Which datarate see you there during speed test?
