Troubleshoot Wi‑Fi Conversations with EYE P.A

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)

    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.

    • (Potential Issues)

      • Non-Standard Channel: Channels 1, 6, and 11 should be used to maximize the available bandwidth in the 2.4 GHz band. When a wireless network is on a non-standard channel, Wi-Fi overhead is increased. This is because the non-standard channels overlap the standard frequencies.
      • High Retransmits: Measuring retransmissions gauges how efficient a network is. In a noisy RF environment, 802.11 devices need to repeat themselves more often. This is because a percentage of transmitted packets are not comprehended by the receiving device. The airtime utilized can potentially double due to retransmissions, thus affecting the overall channel bandwidth.
      • Legacy Data Rates: Wi-Fi networks inherently have overhead to send data across the network. The data rate at which the overhead is transmitted can reduce the performance of the network. Legacy data rate support can increase Wi-Fi overhead by 40%.
      • Legacy Devices Detected: Legacy 802.11 devices in the environment require a significant amount of extra overhead. This reduces the available bandwidth significantly.
      • Protection Mechanism: Protection mechanisms help legacy 802.11 devices coexist with modern wireless networks. To reduce interference, legacy devices must properly cooperate with modern networks by increasing their management overhead. Upgrading all legacy devices and discontinuing legacy data rates in the environment will improve the overall speed of your network.
      • WEP Detection: Wired Equivalent Privacy (or WEP) is weak security encryption and can be compromised very easily.
      • WPS Detection: WPS has a known flaw that makes it vulnerable to brute force attacks, and is considered to be less-than-ideal.

      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.

     

     

     

     

     

     

     

    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

    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.

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.
