Why Can’t I Change the LAN IP Address of the Router to Certain Specific IP Addresses (MG7310, MG7315, MG7540 and MG7550)?

ANSWER:

The MG7550 and MG7540 reserve subnets 192.168.1.x & 192.168.2.x, and 192.168.21.x & 192.168.22.x for Guest networks. These reservations cannot be changed.

The MG7310 and MG7315 reserve subnets 192.168.1.x through 192.168.7.x for Guest networks. These reservations cannot be changed.
