AirPcap Nx is the best USB-based packet capture device for the Windows platform. Easy-to-deploy, this unique dual-band offering supports full packet capture for 802.11 a/b/g/n, featuring 2×2 MIMO with internal antennas or using external antennas via integrated MC-Card connectors for enhanced performance in the most demanding environments.

Quickly examine your 802.11 network and get expert tips to help optimize your Wi-Fi network. Add Eye P.A. software’s innovative visualizations to show at a glance who’s taking up all of the air time, who is using legacy 802.11b data rates, and many other powerful insights that will help you tune up your Wi-Fi network.

AirPcap Nx with Eye P.A. will help you: 

  • Optimize network throughput and capacity
  • Identify “slow talkers”
  • Measure WLAN network retransmission
  • Identify potential DOS Denial of Service attacks

Troubleshoot Wi-Fi Conversations with Eye P.A.

After you’ve ruled out interference, your users may still be experiencing issues. MetaGeek’s Eye P.A. packet visualization software shows you how your channel is being used, packet-by-packet. With just a glance, you can get an idea for the total utilization of air time, packets sent, and bytes present in your capture– the bigger the slice, the more activity taking place.


From here, it’s easy to drill down to exactly what you’re looking for, so you can find and fix packet issues and improve overall network capacity.





Fix Network Misconfigurations

A lot goes into deploying a wireless network, and sometimes settings get overlooked. The Analyze Tab will alert you to a number of potential issues, along with suggested solutions that can help you to increase your network performance.

Eye P.A. will alert you if it discovers high retransmit rates, legacy data rates, and other problematic network settings.

Find Top Talkers and Slow Conversations

Eye P.A. makes it easy to identify slow conversations that could be causing network slowness or inefficiencies. These could be legacy devices on your network, or maybe a certain device that is taking up more than its fair share of airtime. By looking at clients from the packet level, you can see which devices are transmitting, how much airtime they’re taking up, and how fast they’re talking.

Retry Rate Eye PA PNG

During this snapshot, the “Bronco-Wireless” ESSID had a retry rate of 58%, which gives us a good clue that devices are repeating themselves too often.

Filters and Treepies

The best thing about Eye P.A. is its intuitive, visual take on filtering with its multi-layered pie chart (“treepie”) system. With just a few clicks, you can drill down into the exact network conversation that’s causing the problem, without scrolling through hundreds of rows of data in a huge table.


Eye P.A. color-codes subframe types as well, so you can quickly see how much traffic was management overhead (purple and orange), and how much traffic was data payload (blue).

Export To Wireshark

If you use Wireshark to look at packet contents, you can harness Eye P.A.’s powerful filtering capabilities to do the heavy lifting for you, then export only the most important data to Wireshark for row-by-row analysis.

Supported File Types

Eye P.A. visualizes 802.11 captures from a variety of sources, and supports the following file types:

  • WireShark .pcap, .wcap and .pcapng
  • TamoSoft Commview .ncf
  • WildPackets Omnipeek .pkt and .apc (Experimental)
  • Microsoft Network Monitor .cap

Capture 802.11 a/b/g/n Packets with AirPcap Nx

In addition to supporting a variety of packet capture formats, Eye P.A. also supports packet capture with the AirPcap Nx. This 2×2 MIMO device allows you to record 802.11a/b/g/n packet captures in both the 2.4 GHz and 5 GHz bands, and support for AirPcap Nx is built into Eye P.A., so you won’t have to launch another program.
