Positioning Your RSGu3502 for Optimal Wireless Performance

Review the guidelines below before deciding where to place your RSGu3502 in order to achieve the best
wireless performance:

• Connect at least one computer through a wired Ethernet connection.

• Placing your RSGu3502 in the physical center of your network is best, because its antenna sends out signals in all

directions.

• Placing the RSGu3502 in a higher location, such as on top of a cabinet, helps disperse the signal cleanly , especially

to upper floors.

• If possible, position your RSGu3502 in direct line of sight with other home network devices using

a wireless connection.

• Avoid placing the RSGu3502 next to large, solid objects like computer cases, monitors, walls, fireplaces, etc. This

helps the signal penetrate more cleanly.

• Other wireless devices, such as televisions, radios, microwaves, or 2.4 GHz cordless telephones, can interfere with

the signal. Keep these devices away from the RSGu3502.

• Mirrors, especially those that are silver-coated, can reduce transmission performance.

Multicast

Multicasting is a form of limited broadcast. UDP is used to send datagrams to all computers in a host group,
one or more hosts identified by the same destination IP address. The following statements apply to host
groups:

• Anyone can join or leave a host group.

• There are no restrictions on the host location.

• There are no restrictions on the number of members that may belong to a host group.

• A host may belong to multiple host groups.

• Non-members can send UDP datagrams to the host group.

Multicasting is useful when the same data needs to be sent to more than one device; for example, if one
device is responsible for acquiring data that many other devices need. Using multicasting uses less network
bandwidth than sending the same data to individual devices.
Multicasting also enables you to receive multicast video streams from multicast servers. The residential
gateway supports an Internet Group Management Protocol (IGMP) proxy that handles IGMP messages.
When enabled, the residential gateway acts as a proxy for a LAN host making requests to join and leave mul­ticast groups.

Field Description

Establishing Security for Your Wireless LAN

To prevent unauthorized viewing of data transmitted over your WLAN, you must encrypt your wireless trans­missions.

If all of your wireless clients support WPA encryption, we recommend using WPA instead of WEP. The ben­efits of using WPA:

• Provides a much stronger encryption and is more secure

• Provides authentication to ensure that only authorized users can log on to your WLAN

• It is much easier to configure

• It uses a standard algorithm on all compliant products to generate a key from a textual passphrase

Q What does the Motorola RSGu3502 Residential Gateway do?

A The RSGu3502 Residential Gateway is a stand-alone media terminal adapter (S-MTA) containing a home

router:

• As an S-MTA, it converts analog voice signals to and from a standard telephone to digital data that

can be transmitted through a broadband connection across the Internet. It provides an alternate
means to make voice calls.

• Its built-in router provides full network connectivity, a firewall, and VPN passthrough.

Q Will the RSGu3502 Residential Gateway work with a cable modem or DSL modem?

A Yes. The RSGu3502 Residential Gateway supports DHCP, which is specified for DOCSIS

modems, and PPPoE, which is used by most DSL providers.

Q Can I operate a virtual private network (VPN) application behind the RSGu3502?

A Yes. The RSGu3502 Residential Gateway supports IPSec and the most common VPN protocols.

Q Can I play online games through my RSGu3502?

A By default, the residential gateway blocks all unsolicited messages to the computer or local network as

a standard security measure. However, for online games that require some unsolicited messages to be
transmitted through the residential gateway, you can specify ports and IP addresses on which to allow
unsolicited messages. The RSGu3502 enables you to set up virtual servers or a DMZ.

Frequently Asked Questions 71

Frequently Asked Questions

Q How do I configure the RSGu3502?

A Most people can send and receive calls immediately after completing installation. You can configure

your home or office network through a GUI using a connected computer configured to obtain its IP
address using DHCP. Or, you can configure the computer statically to 192.168.15.xxx (xxx is from
2 to 254), subnet mask 255.255.255.0, and default gateway 192.168.15.1.

Q What is included with the built-in router?

A The RSGu3502 supports a firewall, RIP, port triggers, advanced ALGs such as RSVP, POP3, SNMP, and

streaming media. No separate routers are needed.

Q Is any Quality of Service (QoS) implemented on the RSGu3502 Residential Gateway?

A Although VoIP service is typically best-effort, the RSGu3502 provides upstream voice prioritization to

ensure that upstream voice data has priority over other Web data. This ensures good voice quality even
during heavy upstream data transfers, such as e-mail synchronization or file sharing.

IP address and subnet mask to each client. It enables the automatic reuse of unused IP addresses.

The RSGu3502 can simultaneously be a DHCP client and a DHCP server:

• A DHCP server assigns a WAN IP address to your RSGu3502.

• The RSGu3502 contains a built-in DHCP server that assigns private IP addresses to each

computer on its LAN.

DMZ A “de-militarized zone” is one or more hosts logically located between a private LAN and the

Internet. A DMZ prevents direct access by outside users to private data. (The term comes from
the geographic buffers located between some conflicting countries such as North and South
Korea.) In a typical small DMZ configuration, the DMZ host receives requests from private LAN
users to access external web sites and initiates sessions for these requests. The DMZ host cannot
initiate a session back to the private LAN. Internet users outside the private LAN can access only
the DMZ host. You can use a DMZ to set up a web server or for gaming without exposing
confidential data.

DOCSIS The Data-Over-Cable Service Interface Specification define a standard interface for cable modems

to deliver data between a cable network and computer systems. Euro-DOCSIS is DOCSIS adapted
for use in Europe.

DNS The Domain Name System is the Internet system for converting domain names to IP addresses. A

DNS server contains a table matching domain names such as Internetname.com to IP addresses
such as 192.169.9.1. When you access the Web, a DNS server translates the URL displayed on the
browser to the destination website IP address. The DNS lookup table is a distributed Internet
database; no one DNS server lists all domain-to-IP address matches.
