Manage Network Access Control Lists
You can use access control to block or allow access to your network. An access control list (ACL) functions with the
MAC addresses of wired and WiFi devices that can either access your entire network or are blocked from accessing
your entire network.
The modem router can detect the MAC addresses of devices that are connected to the network and list the MAC
addresses of devices that were connected to the network.
Each network device owns a MAC address, which is a unique 12-character physical address, containing the
hexadecimal characters 0–9, a–f, or A–F (uppercase or lowercase) only, and separated by colons (for example,
00:09:AB:CD:EF:01). Typically, the MAC address is on the label of the WiFi card or network interface device. If you
cannot see the label, you can display the MAC address using the network configuration utilities of the computer.
You might also find the MAC addresses through the web pages of the modem router (see View Devices Currently
on the Network on page 234).
Add Devices to or Remove Them From the Blocked List
If you set up an access list that allows all new devices to access your network but you want to block some devices
from accessing your network, you must specify the devices that you want to block.
To add or remove devices that are blocked:
1. Launch a web browser from a computer or WiFi device that is connected to the network.
2. Enter http://www.routerlogin.net.
