Hitron HT-EMN2 User’s Guide
Once authenticated, devices that have joined a network via WPS use the WPA2
security standard.
2.6 Guest Networks
Your HT-EMN2 supports the creation of a wireless guest network. A guest network
enables you to allow temporary visitors to access your wireless Internet connection
without revealing your primary network password(s). Computers connected to the
guest network can access the Internet connection only, and have no access to other
computers or devices on the wireless or wired network.
2.7 MAC Addresses
Every network device possesses a Media Access Control (MAC) address. This is a
unique alphanumeric code, given to the device at the factory, which in most cases
cannot be changed (although some devices are capable of “MAC spoofing”, where
they impersonate another device’s MAC address).
MAC addresses are the most reliable way of identifying network devices, since IP
addresses tend to change over time (whether manually altered, or updated via
DHCP).
Each MAC address displays as six groups of two hexadecimal digits separated by
colons (or, occasionally, dashes) for example 00:AA:FF:1A:B5:74.
NOTE: Each group of two hexadecimal digits is known as an “octet”, since it
represents eight bits.
Bear in mind that a MAC address does not precisely represent a computer on your
network (or elsewhere), it represents a network device, which may be part of a
computer (or other device). For example, if a single computer has an Ethernet card
(to connect to your HT-EMN2 via one of the LAN ports) and also has a wireless card
(to connect to your HT-EMN2 over the wireless interface) the MAC addresses of the
two cards will be different. In the case of the HT-EMN2, each internal module (cable
modem module, Ethernet module, wireless module, etc.) possesses its own MAC
address.
