A: Using the B49G Router as a DHCP server By default, the router will
function as a DHCP (Dynamic Host Configuration Protocol) server,
allowing it to assign IP, DNS server, and default gateway addresses to all
computers connected to the router's LAN. The assigned default gateway
address is the LAN address of the router. IP addresses will be assigned to
the attached PCs from a pool of addresses specified in this menu. Each
pool address is tested before it is assigned to avoid duplicate addresses
on the LAN. DCHP helps prevent IP conflicts.
Q: What is the IEEE 802.11g standard?
A: The IEEE 802.11g standard specifies data rates of up to 54 Mbps in the
2.45-GHz band. It uses Orthogonal Frequency Division Multiplexing
(OFDM), which is provided by this standard and is compatible with
802.11b standard offering speeds of about 11 Mbps. This standard uses
Complementary Code Keying (CCK) modulation. Both 11g and 11b can
operate at a range of up to 300 feet.
