RT3200 optimal wifi settings

Can someone review my 5GHz settings for my new AX router (Belkin RT3200)? Any suggestions to get the best preformance from the router? I only use 5 GHz, no 2.4 GHz.

Mode = AX
Channel = 157
Width = 80 MHz
Maximum transmit power = 23 dBm (199 mW)

Encryption = WPA3-SAE
802.11w Management Frame Protection = Required
Enabled key reinstallation (KRACK) countermeasures = On

DTIM Interval = 3
Short preamble = On
Disassociate on low acknowledgement = On

Country Code = US
Coverage cell density = High
Beacon Interval = 101

This is /etc/config/wireless

config wifi-device 'radio0'
	option type 'mac80211'
	option path 'platform/18000000.wmac'
	option channel '1'
	option band '2g'
	option htmode 'HT20'
	option disabled '1'

config wifi-device 'radio1'
	option type 'mac80211'
	option path '1a143000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0'
	option band '5g'
	option htmode 'HE80'
	option country 'US'
	option cell_density '2'
	option beacon_int '101'
	option txpower '23'
	option channel '157'

config wifi-iface 'wifinet2'
	option device 'radio1'
	option mode 'ap'
	option encryption 'sae'
	option dtim_period '3'
	option wpa_disable_eapol_key_retries '1'
	option network 'lan'
	option ssid 'Lowjack'
	option key 'secret'

config wifi-iface 'wifinet3'
	option device 'radio1'
	option mode 'ap'
	option ssid 'LowjackGuest'
	option encryption 'sae-mixed'
	option dtim_period '3'
	option key 'secret'
	option ieee80211w '2'
	option wpa_disable_eapol_key_retries '1'
	option network 'guest'

you should probably read Belkin RT3200/Linksys E8450 WiFi AX discussion

@frollic - I have started to do but it is over 1000 replies and some are old so I don't know what content is current. Like the first post from 8 months ago says AX mode is broken but it is not now. Is there any specific discussion in it you think recommend to me about the settings? Thank you.

start reading from the bottom instead .... :wink:

But I think 160MHz is available too ?

Those are good settings, though they will restrict some usages. All clients must be WPA3-capable, and the cell density 2 means the signal will not reach far away users. That is actually good for speed, but you may need to trade back for coverage if you only have the one router as the single wifi AP serving a whole house.

160 MHz operation is possible but the chip drops down to two RF chains instead of 4.
