1. If your ISP checks the MAC address
Some ISPs checks the user device (usually a computer) MAC address before assigning a WAN IP address. If
the MAC address matches one on the ISP＇s system, the ISP sends an IP address to the user device and allows
Internet access. However, if the user connects another computer with a different MAC address directly to the
modem, the ISP discards any DHCP discovery packets from the un-authorized MAC address and no IP address
is assigned.
You can set the P-2024 to copy the MAC address of the computer whose MAC address is authorized by the ISP.
The P-2024 will use the copied MAC address as its WAN MAC address.
In SMT menu 2, enter the computer MAC address. The P-2024 will use the copied MAC address as its
WAN MAC address and update SMT menu 24.1.
