3 1. Getting Started First, check out all the cool features. Now, Turn it On AirCheck is Ready to Go in Under Three Seconds Starts Scanning Channels and Networks Immediately Bottom center of display shows channel being scanned and number of AP s detected Indicates Link to AP Restart All Tests Return to Prior Screen Supports a/b/g/n Lithium Ion Battery 5 + hours life Indicates AirCheck is Transmitting Optional Directional Antenna Connector (on back) USB Access for Upgrades and Reports Save Session Reports Return to Home Screen 3

4 2. Finding Networks and Access Points Make sure Networks is highlighted on the home screen and press SELECT You ll see a list of all the networks detected. (A network is a collection of AP s with the same name (SSID).) Use the left and right arrows to scroll the display for more information Press the Legend (F2) softkey for an explanation of symbols Security Signal Strength Number of AP s Network Type 4

5 3. Drill in on an AP Use the Arrow Keys to select a network Press SELECT to see a list of AP s on that network If the AP is not named, then its manufacturer s name and MAC address is displayed If you re looking at a small office or home network, there will probably be only one AP per network. Press SELECT again to see details of the selected AP 5

6 4. Locate an AP Press Locate (F2) for a real time graph of the AP s signal strength As you move closer to or further from the AP, you will see the signal strength change Note that measurements are expressed in negative dbm, which means that a signal of -30dBm is stronger than one of -40dBm 6

7 5. Discover Clients Associated to an AP Press the Back key to go back to AP details You can discover client devices (typically PCs or smartphones) that are associated with the selected AP. Select Clients to view associated clients Press SELECT again to see details of the selected client 7

8 6. Locate a Client Press Locate (F2) for a real time graph of the client s signal strength As you move closer to or further from the client, you will see the signal strength change Note that measurements are expressed in negative dbm, which means that a signal of -30dBm is stronger than one of -40dBm 8

9 7. Discover All Client Devices You can also discover all the clients devices that are in an area instead of just associated to an AP Return to the main screen by pressing the Home key Select Clients to see a list of probing and associated clients in the area A client is associated if an SSID is listed for the client and probing if an SSID is not listed Press SELECT again to see details of the selected client Press Locate to locate these clients just like the ones associated to an AP Associated client Probing client 9

10 8. Setting an AP s Authorization Status (ACL) The Access Control List (ACL) lets you tag AP s so that you can quickly identify ones that that should not be there.

11 9. Channel Usage and Interference AirCheck can scan all Wi-Fi channels for AP s, traffic, and interference Press the Home key, then select Channels and press SELECT Press Legend (F2) for an explanation of this screen Interference shows up as gray bars You can generate interference with a microwave oven (be sure to put something such as a cup of water in it before starting it) or a Bluetooth device it will show up on the display A Bluetooth device needs to be in search/discover mode to generate significant interference. Press AP List (F1) for a list of AP s on a selected channel Not much interference Significant interference 11

12 10. Connecting to a Network You can connect to an open network or a secured network. If your network security requires a certificate then you will need to use AirCheck Manager software to include the certificate in your profile You can connect to a network or a specific AP from a number of different screens by pressing Connect (F1). For this example, press the Home key, select Networks then select the desired network and press Connect (F1) AirCheck s connection test includes three parts, as noted on the screen: Establish connection with AP Obtain IP address with DHCP Ping Gateway and DHCP Server 12

13 11. Configure AirCheck for a Secured Network If your network is secured, you will need to configure AirCheck to connect to the secured network If you do not already see this screen, select a secured network and press SELECT. Press Ok to configure the network Select your desired Authentication type and press Next (F1) Select your desired Encryption type and press Next (F1) Select your desired EAP type and press Next (F1) 13

14 11. Configure AirCheck for a Secured Network If your chosen security requires a username and password you will need to enter them now Select Set username and press SELECT Enter your username using the keyboard. Press Save (F2) when done Enter and save your password Press Done (F2) when complete AirCheck will connect to the access point using the configured security 14

15 12. Testing Signal Quality When connected to a network, you can run a continuous signal quality test by pressing Start Tests (F1) From here you can choose to PING the gateway, DHCP server or enter another address. Choose the gateway and press SELECT AirCheck will ping continuously and display the connection quality in a realtime graph. Move around your area and see how the connection quality is affected. 15
