2-2-1-1 Scan for Other Wireless Devices
There are two kinds of wireless connection mode: Infrastructure andAd-Hoc.
Infrastructure mode is used by wireless access points, which is able to establish
wireless connection for you and other wireless / wired network clients.
Ad-Hoc mode is also know as „point-to-point‟ mode, and in this mode, wireless devices
such as computer or PDAwill not be capable to establish wireless connection with more
than one wireless device, and is suitable for establishing a one-to-one wireless
connection between two wireless devices.
Before you can connect to any wireless access point or device by infrastructure or
Ad-Hoc mode, there two things you must know:
a. Wireless device‟s „SSID‟ (Service Set IDentifier, someone will call it „access point‟s
name‟).
You can scan for the SSID of other wireless devices nearby, but if the SSID of the
wireless device you wish to connect is hidden, you must know exact SSID before
you can establish connection with it.
b. If the wireless device you wish to connect uses encryption, you must know its
encryption key.
Please launch Edimax setup utility and it will scan for wireless access points near by:

16
Scan results will be displayed here, please check if the wireless device (access point or
another computer) with the SSID you wish to connect is shown here.
Scan result includes 6 types of information, they are:
A The SSID (Service Set Identifier) of wireless device. If nothing is displayed here, it
means the SSID of this wireless device is hidden.
If a symbol appears in front of the name of wireless device, means you’ve
established connected with that wireless device.
B The type of this wireless device and the channel number of this wireless device.
Means this wireless device is an access point
Means this wireless device is a computer (Ad-Hoc mode, point-to-point
connection)
C The wireless standard supported by this access point.
‘n’ for 802.11n , ‘a’ for 802.11a , ‘g’ for 802.11g and ‘b’ for 802.11b
.
WPS icon will appear when the access point supports WPS. If the
access point uses encryption, a key icon will appear.
Note: When the access point supports WPS and WPS icon is appeared, you will not
see the key icon here even through the access point uses encryption.
DShows the signal strength of access point by percentage.
E Shows the bar graph of the signal strength.

If you can not see the access point you wish to connect here, please click „Rescan‟
button to scan for access point again, until the one you preferred is displayed. You may
have to click „Rescan‟ for more than two times before you can see the access point you
wish to use here.

than five times, please move your computer closer to the location where the wireless
access point is, or see instructions in Chapter 3-2 „Troubleshooting‟.
