Nighthawk RAX15 -LAN setup change subnet mask but it does not get change

    Under Netgear LAN menu setup, I change the subnet mask  from 255.255.255.0 to 255.0.0.0   and click apply.

 

   But checking network setting using "ipconfig/all" the subnet mask never got change -still the old 255.255.255.0.  Re-Checking the LAN menu setup it show the new subnet 255.0.0.0.    I tried hard reset power on the router and perform  ipconfig/all it still shows 255.555.555.0   even though the LAN menu setup has the correct 255.0.0.0 .     I also tried disabling DHCP but still not change.

 

thanks
