1.3 Signal Range
The signal range of ASRock WiFi-802.11n module varies from the operating
environment. Obstacles such as walls and metal barriers could reflex and absorb ratio
signals. Devices like microwave ovens may also interfere with the wireless network
greatly.
Signal range:
Indoor 330ft (100m), outdoor 980ft (300m)
By default, ASRock WiFi-802.11n module should automatically adjust the data rate.
The closer the wireless stations are the better the signal and transmission speed they
will receive.
Note:
* To reach higher data rate, we advise users to adjust the channel bandwidth of Wireless AP to
40MHz instead of 20MHz. However, under the circumstances of a noisy environment, users
may adjust the setting back to 20MHz, which may get less interference.

2.4 Utility Setup
After you have installed the driver and utility to your system, now you are ready to set
up the utility in your network. ASRock WiFi-802.11n module supports two kinds of
wireless network mode: Access Point Mode (AP Mode) and Station Mode. Please
refer to below introduction and select the most appropriate mode when setting it up.
A. Access Point Mode (AP Mode)
If you want to share the Internet access with the wireless stations in your
environment, such as PC, notebook and other devices, you can configure ASRock
WiFi-802.11n module in an access point mode (AP mode). In this mode, ASRock
WiFi-802.11n module becomes the wireless access point that provides local area
network and Internet access for your wireless stations. The AP Mode feature is ideal
for home/SOHO networks with several computers, a shared printer, and a shared
Internet connection.

B. Station Mode
If you do not plan to use AP function with ASRock WiFi-802.11n module, but just
want to use the wireless function to connect the access point (AP), or connect
with other stations in the wireless range instead, please set up ASRock WiFi-802.11n
module in station mode. There are two choices provided in station mode:
Infrastructure mode and Ad-hoc mode. Please read below introduction for the
differences of these two modes.
B-1. Infrastructure Mode
If you have a present access point (AP) in your wireless network environment for this
station to join, you can set up ASRock WiFi-802.11n module in Infrastructure mode.
In this mode, ASRock WiFi-802.11n module acts as a wireless adapter. In other words,
it is centered on an AP that provides Internet access and LAN communication for the
wireless stations, such as PC, notebook and other devices.
