  • Clients
  • Interferers
  • AutoTest
  • Ethernet Test

Performs the following five essential Wi-Fi tests and a pass/fail indication of the wireless environment and identifies common problems — for any level of expertise.

  • 802.11 Utilization – Reports the top three channels in each band (2.4 GHz and 5 GHz) with the highest 802.11 Wi-Fi traffic airtime utilization.
  • Non-802.11 Utilization – Reports the top three channels in each band (2.4 GHz and 5 GHz) with the highest non-802.11 airtime utilization. This indicates the presence of interference sources and high noise levels
  • Co-Channel Interference - Reports the top three channels in each band (2.4 GHz and 5 GHz) with the most APs on the same channel that exceed the minimum signal level threshold. It accounts for 40-MHz and 80-MHz channels in the 5-GHz band by counting an AP on its primary and each secondary channel. Then view a list of the APs counted for co-channel interference.
  • Adjacent Channel Interference - Reports the top three channels in the 2.4 GHz band in which APs may experience Adjacent Channel Interference. For each channel on which at least one AP is found, the Tester counts how many APs are operating on other channels that overlap with that channel. It accounts for 20-MHz and 40-MHz channels in the 2.4-GHz band. Then view a list of the APs counted for adjacent channel interference.
  • Network Quality – Verifies coverage, interference, security and ability to connect to specified networks, along with the availability of critical network services such as DHCP and connectivity to specified network targets.

Cloud Based Results Management

Link-Live Cloud Service
Serving as a centralized test results and reporting database, Link-Live transforms team workflows with the ability to log, document, and report test activity from all your sites. This complementary internet-hosted service is available from anywhere at any time using any device with a browser and internet connection. Enabling collaboration with remote experts, Link-Live saves time in problem escalations, and provides a baseline of test results useful for future troubleshooting or network change planning.

Once the AirCheck G2 is connected to the Link-Live Cloud service, AutoTest and connectivity test results are automatically uploaded to the dashboard for project management and reporting. You will have the option of uploading session files, screenshots, profiles, packet captures, location information, and comments anytime. Also, your AirCheck (running version 3.0 or greater, with Gold Support) can receive firmware updates “over the air” as they become available.

Link-Live is especially useful for managers of remote teams that need visibility to test results instantly or would like an easier way to manage AirCheck G2 units on the field. In addition, teams that utilize the wired-only companions to the AirCheck G2 such as the LinkSprinter or LinkRunner G2 have a single dashboard system to manage results from network connectivity tests.


Easily configure, manage, and control the use of your AirCheck G2 – or an entire fleet of them - with the Profiles feature, which allows configuration of security settings, AutoTest limits, and target devices for connectivity. Remotely transfer multiple profiles into your AirCheck G2 testers from Link-Live, as needed for different facilities.

Record Session

Ideal for collaboration and escalation support, your remote experts can easily review detailed information about networks, access points, channels, or clients on Link-Live by viewing a saved session file. The session files will capture details including AirCheck G2 configuration, AutoTest results, lists of AP’s / clients and channel usage.

AirCheck G2 Manager Software
For those without access to the cloud, the AirCheck G2 Manager Software provides the ability to manage AirCheck G2 profiles and view detailed information on saved tests results locally. The AirCheck G2 Manager is free and available for download to any Windows computer from the Link-Live Cloud Service or the NETSCOUT® support site.


Quickly view all the networks present in the environment, and see critical parameters for each one including signal level, signal/noise ratio, security type, and number of access points. Find common issues such as mixed security types, poor signal coverage or lack of secondary AP coverage.

Sort or filter on any parameter. Then drill into more details for any network, including 802.11 types supported, number of connected clients, channels and more. From the network details page, drill into a list of APs or clients on the network.

Access Points

Quickly view all the APs present in the environment, and see critical parameters for each one including signal level, signal/noise ratio, security type, and channel. Find common issues such as incorrect security type, poor signal coverage or incorrect channel.

Sort or filter on any parameter. Then drill into any AP to set its authorization level and see more details, including number of connected clients, supported rates, 802.11n and 802.11ac capabilities and more. From the AP details page, drill into a list of connected clients or the channel on which the AP operates to verify any channel utilization or co-channel interference problems.

Network Connection Tests

Verify network availability and access to critical services by connecting to a network (SSID) or AP with a single touch on the Connect button. Key test steps include:

  • Associate with AP
  • Request and receive an IP address from a DHCP server
  • Ping the default gateway and DNS servers for availability
  • Perform a ping or TCP port test on up to ten network targets
  • Ongoing signal level, signal/noise ratio, and retry rate measurements

Once connected to a network, perform a roaming test to validate that roaming is enabled on the network, or run an iPerf performance test to verify throughput capabilities on the network.

Channel Utilization and Interference

Quickly determine if channels are over-utilized with 802.11 Wi-Fi traffic and/or with non-Wi-Fi interference and noise. Automatically detect devices that can cause interference, including microwave ovens, wireless game controllers, Bluetooth® devices, Zigbee devices and wireless video cameras. You can also drill in to see the level of Wi-Fi traffic and interference over the last 60 seconds on a selected channel, as well as the access points, clients, and interferers using this channel.

Wired Ethernet Tests

Access points must have a working backhaul connection to the network, and the AirCheck G2’s built-in Ethernet test validates that.

  • Diagnose and test Power over Ethernet (PoE), Link to the switch, DHCP, Gateway, and Internet connection.
  • Get VLAN, switch name, and port information via CDP/LLDP/EDP for your managed switches
  • Automated reporting to Link-Live Cloud Service
  • Get detailed test results sent directly to your email
Rogue Detection/Location, Client Details

Client Details provides essential information about specific devices and their configuration. Track down rogue APs and unauthorized clients by following the real-time signal level meter and graph over time. Audible indication is provided, and the use of a USB headset for private audio is supported. Optional external directional antenna saves significant time when locating devices.

Multiple Language Support

AirCheck fully supports multiple languages including English, French, German, Spanish, Portuguese, Russian, Japanese, Simplified Chinese, Traditional Chinese and Korean.

See what people are saying about the AirCheck G2

"It’s my favorite WiFi diagnostics tool, hands-down. It does so many things in such a small, rugged form factor that it’s impossible not to love. As soon as I first saw it, I knew NetScout had a winner!"

– Devin A

“Netscout has clearly hit a home-run with the AirCheck G2. Not only is it a perfect replacement for the venerable generation 1 AirCheck, it comes packed with features that will make it the triage tool of choice for Wi-Fi professionals everywhere. In addition to the 802.11ac and touch screen functionality, Netscout raised the bar by integrating wired testing directly into the unit - a must have for not only RF Designers but Access Point installers. Couple the new features with Cloud integration and it's the perfect tool for a distributed nationwide team, or a tactical one on one engagement. The 'at a touch' insight that the AirCheck G2 brings to our team throughout all cycles of lifecycle management makes it an invaluable asset to all levels of Wi-Fi admins, engineers, and designers.

– Sam Clements, Mobility Practice Manager

“The G2’s biggest advantages are in its wireless capabilities, controls, and system management. While the first AirCheck topped out at 11n support, the G2 does 3x3 802.11ac to bring updated functionality for the fast-growing 11ac space…. Right now, there just isn’t a feature-for-feature equal to the AirCheck on the market, and the introduction of the G2 stretches the gap.”

Lee Badman, Network Engineer & Wireless Technical Lead

“The Netscout Aircheck G2 felt kind of like a “Star Trek” device for sniffing out Wi-Fi.  With just one button I could see how congested certain channels were at home.  I’ve seen smartphone apps that provide basic functionality, but not as complete as what the Aircheck G2 does.”

- Andy Chen, The Gadgeteer

"The AirCheck G2 is a fast, portable, and accurate way to troubleshoot wireless problems and verify on - air configuration. They are great in large stadiums during live events, where you just can't carry laptops or tablets safely.  The direction finding capability makes it incredibly simple and fast to hunt down rogue APs.  It pays for itself quickly by saving significant network engineer time to complete routine tasks.“

- Chuck Lukaszewski, VP, Wireless Strategy & Standards

“The older AirCheck was my #1 go-to tool for testing and troubleshooting Wireless LANs… now with this upgraded AirCheck G2 they have incorporated most of my list of ‘make a wish’ items into the smart, light, and fast tool. All the benefits of the old AirCheck with updated 802.11ac features and a touch-screen for increased ease of use. The new NetScout AirCheck G2 adds testing Ethernet ports, including the fantastic Link-Live that ‘self-documents’ all my tests.  These upgrades, coupled with the wired-side testing, and all tied to the Link-Live features make this my new favorite tool of choice!"

- Keith Parsons, Managing Director at Wireless LAN Professionals, Inc.

“The AirCheck has long been the go to device for quick testing and troubleshooting of wireless networks. The new G2 continues that tradition bringing a strong technical & user interface update to the product and when coupled with Link-Live increases workflow efficiencies for field technicians. By introducing Link-Live support to the AirCheck product line data from field technicians can easily and quickly be reviewed by remote architects and engineers, providing feedback prior to field technicians leaving a site.”

– Blake Krone, Mobility Consultant, CCIE #31229 (Wireless), CWNE #152

“Simply seeing what is nearby is cool but testing the network is where the AirCheck G2 begins to pay for itself. With the ability to associate to WPA2 Enterprise network (and all lesser options) with a great variety of EAP options the AirCheck can squash the time required to audit and test connecting to wireless networks. This is a good idea after deploying new infrastructure. ”

– Matt S. Principal Technologist
