AirCheck Getting Started Guide

Accessing the Users Manual

This guide provides basic information to help you get

started using the tester. For additional information, see

the AirCheck Users Manual on the Product CD.

WWarningX

To prevent possible fire, electric shock,

personal injury, damage to equipment, or

inaccurate test results, read the safety

information in the AirCheck Users Manual

before using the tester.

Battery Charging and Life

first time. To charge the battery, connect the ac adapter

to the battery connector.

The battery life is approximately 5.5 hours during

typical operation.

Shows the battery status. When the battery

charge is low, the icon blinks.

AirCheck Getting Started Guide

Minimum Configuration for the Best

Performance

To change the language and country settings

Select Tools.

To change the language for the screens, select Set

Language. Highlight a language, then press !

Save.

To change the country, select Set Country, then

select the country where you will use the tester.

To get the most performance from your tester, use

AirCheck™Manager software to configure a profile and

upload it to the tester. A profile contains data that lets

the tester do these tasks:

•

Connect to networks that require security

credentials

•

Show the correct authorization status for each

access point. This lets you quickly see which access

points are authorized parts of the network.

•

Ping key network devices.

Discover Networks and Access Points

To discover networks or access points, select Networks

or Access Points from the home screen. Figure 1 shows

the Networks list.

To see details about a network or access point, use "

#to highlight the network or access point, then press

Discover Networks and Access Points

Figure 1. Networks List

: The time when the tester first heard the

networks. To see networks that come into range as

you move through an area, sort the list in

descending sequence for the timestamp column.

Press %, then move through an area. Networks

that come into range are added to the top of the

list. Networks that become out of range become

gray if Gray inaudible access points is enabled.

ACL: The authorization status of the access point.

The default status is Unauthorized device.

Change the status of each access point to show how

it is related to your network. To change the status,

select Access Points from the home screen, select an

access point, then press !ACL.

(...): All access points in the network do not have the

same authorization status.

: The maximum signal strength of all the

access points for a network SSID.

ABCDE F G

AirCheck Getting Started Guide

: The security status of the network:

Red open lock: The network does not have

security enabled.

Yellow closed lock: One or more access points

use WEP or Cisco LEAP security protocol. These are

less secure than other protocols.

Green closed lock: All access points use security

protocols that are more secure than WEP, for

example, WPA or WPA2.

(...): All access points in the network do not use the

same type of security. For example, one uses WEP

and another uses WPA.

: The number of access points the tester hears at

your location.

SSID: Service Set Identifier. The name of the wireless

network.

: The network has ad hoc devices. These are

devices that communicate directly with other

devices, not through an access point. Ad hoc devices

can give hackers access to data transmitted on the

network. (Some IT policies for networks allow ad

hoc devices.)

[Hidden]: The network does not broadcast its SSID.

Discover Networks and Access Points

802.11: The 802.11 standards that the access points

in the network use:

802.11a: Uses the 5 GHz band.

802.11b: Uses the 2.4 GHz band.

802.11g: Uses the 2.4 GHz band.

802.11n: Can be used in the 2.4 GHz or 5 GHz

bands.

Red bars: The tester received a country code

that is different from the setting in Tools > Set

country. To identify the network or access point

that transmits the code, select Networks or Access

Points, then look for the red bars in the 802.11

column.

: One or more access points use a

bonded channel. Access points that use the 802.11n

standard can bond a channel with an extension

channel above ( ) or below it ( ) to make

one 40 MHz channel. This wider channel gives the

network higher throughput.

(...): All access points in the network do not use the

same 802.11 standard.

Notes: Press &to scroll to the notes field. The tester

adds notes automatically. Networks that have notes

are purple.

(...): The network has multiple notes. To see all the

notes, highlight the network, then press $twice
