Infrastructure

Mode

In Infrastructure mode, a wireless client communicates with other wired and

wireless clients through an AP router. A wireless client connected in this way can

access resources of Ethernet or wireless LANs connected to the AP router, including

access to the Internet using a shared modem.

Setting Up

Wireless LANs

When setting up a wireless LAN, take note of the following points:

❑

Start by determining the areas to be networked, the number of users and the type of

devices to be used. Then determine if you require AP routers and where they should be

placed.

❑

If two AP routers are placed close to each other, you can optimize your bandwidth by

setting them to different channels.

❑

Radio waves can pass through walls and glass but not metal. If the signal on the other

side of a wall is weak, it may be that the wall has reinforcing metal in its structure. Install

another AP router to circumvent this problem or move your AP router to another location.

❑

Floors usually have metal girders and metal reinforcing struts that impede radio waves.

Frequently Asked Questions

Turbo-G

Your Creative wireless device comes equipped with Turbo-G™ technology,

which improves your device's performance by 35%, without affecting that of

other wireless local area network (WLAN) devices in the neighbourhood. By

installing a few Turbo-G capable devices in the network, overall networking

speed can be dramatically improved. Turbo-G technology is fully compliant

with 802.11g and 802.11b standards.

When using a Turbo-G capable device to surf the Internet

wirelessly, why is there no speed improvement?

Turbo-G capable devices do not affect your Internet connection speed. Your

Internet connection speed depends on your modem and your Internet service

plan. It is unrelated to your use of Turbo-G devices.

Will my wireless networking speed slow down when a non-Turbo-G

capable device joins the wireless network?

Your wireless networking speed may slow down when a non-Turbo-G capable

device joins your wireless network. Your Turbo-G capable device, however, will

always continue to maintain a higher performance speed than standard

802.11g or 802.11b devices.

How do I obtain maximum wireless networking performance?

Make sure that your access point and wireless client are Turbo-G capable.

Disable your wireless security options (for example, Wired Equivalent Privacy,

Advanced Encryption Standard or WiFi Protected Access) in your web

configuration.
