Need Assistance with MediaTek7628 2.4GHz Network Restart Issue

I'm encountering an issue with my MediaTek7628 2.4GHz network where the following error messages are logged:

[139968.236344] phy0-sta0: authenticated
[139968.251532] phy0-sta0: associate with 58:d5:6e:aa:1f:85 (try 1/3)

[139971.588023] phy0-sta0: deauthenticated from 58:d5:6e:aa:1f:85 (Reason: 15=4WAY_HANDSHAKE_TIMEOUT)

This issue occurs during the MediaTek7628 2.4GHz network restart, and I'm unsure how to resolve it. Below is my wireless setup configuration:

cat /etc/config/wireless

config wifi-device 'radio0'
        option type 'mac80211'
        option path 'platform/10300000.wmac'
        option channel '1'
        option band '2g'
        option htmode 'HT20'
        option txpower  '200'
        option disabled '0'

config wifi-iface 'default_radio0'
        option device 'radio0'
        option network 'lan'
        option mode 'ap'
        option ssid 'OpenWrt'
        option encryption 'none'
        option disabled '0'

config wifi-iface
        option device 'radio0'
        option network 'wwan'
        option mode    'sta'
        option disabled '0'
        option key     'xxxxxxx'   # my router's ssid password
        option encryption 'psk2'
        option ssid    'xxxxxx'    # my router's ssid name

I would greatly appreciate any insights or suggestions on troubleshooting and resolving this issue.

Thank you for your assistance!

Best regards,

Steven
