DHCP clients are having netmask 0.0.0.0

[ppfoong]

I just noticed all my DHCP clients are having netmask of 0.0.0.0 instead of 255.255.255.0 for my 192.168.0.x network.

Firmware 3004.388.11 on RT-AX86U with YazDhcp 1.2.5

Is this normal?

Subnet mask in LAN IP setting page is 255.255.255.0

There is no subnet mask setting in DHCP page.

DHCP IP pool range is 192.168.0.101 to 192.168.0.199

No. Check the contents of /etc/dnsmasq.conf for corruption.
