This is important, because the results of the test depend on the driver that is used. The newer the driver, the better the chances that it will work with CommView for WiFi.

Finally, you may want to buy a compatible card, as they are not terribly expensive these days. Or simply order a boxed version from us; it comes with a compatible USB adapter. What adapter would you recommend for use with your application? By using this list, you choose the best adapter based on the form factor USB, Integrated, etc. Generally, the best choice would be an Which supported adapters have external antenna connectors?

Can I capture data from multiple channels simultaneously? Yes, if you use multiple supported USB adapters. Please refer to the Multi-Channel Capturing chapter for more information.

I've installed the special driver for my adapter and now the adapter cannot connect to my wireless network after I close CommView for WiFi. What could be the problem? When you replace the driver for your adapter, the configuration settings including preferred networks and passwords may be lost, so you may have to re-configure the adapter.

If your adapter has been configured and still can't connect, please disable and re-enable it in Device Manager, this will restore the connectivity. Some of the channels are not available in the channel selection controls. Is this normal? What if want to monitor these channels? The answer depends on the adapter:. The channels that are available for use in a particular country differ according to the regulations of that country. The firmware of the wireless adapters being sold in the US is typically configured to disallow channels 12 and Dell or Broadcom : enabling channels 12 and 13 may be possible.

You will see the file named ch Double-click on that file to execute it. Restart CommView and these channels will become available for selection. Note that the adapter's ability to capture packets on channels 12 and 13 depends on the regulatory domain set by the laptop vendor. If the vendor enabled them in your case, there won't be a problem. However, we've heard of many examples when laptop vendors did not enable channels 12 and 13 even in the laptops that were sold in a country where these channels were legal.

When monitoring a WLAN, can I be sure that the program will capture every packet being sent or received? No, and here is why.

When a wireless station is connected and authenticated, the station and access point s employ a mechanism that allows them to resend the packets that were not received by the other party or damaged en route for some reason e.

In case of CommView for WiFi, the wireless adapter is put into passive, monitoring mode. Therefore, the adapter cannot send "requests" to have packets resent, nor can it acknowledge successful receipt of packets.

This results in loss of some packets. The percentage of lost packets may vary. Generally, the closer to other stations and access points you are, the fewer packets will be dropped. WPA3 cannot be decrypted. WPA3 uses the passphrase only for authentication; decryption is impossible. I'm on a WLAN with high traffic volume, and it's hard to examine individual packets when the application is receiving hundreds of thousands of packets per second, as the old packets are quickly removed from the circular buffer.

Is there anything I can do about it? Increasing the buffer size improves the voice quality but increases the delay. The main problem is the significant time discrepancy between the streams that belong to different VoIP calls, aside from the fact that it makes no sense to listen to unrelated audio that is part of unrelated calls. The functionality that allows selecting arbitrary RTP streams for subsequent playback is provided solely for manual recovery of a call from several streams in cases where parent SIP or H.

After clicking on the Play button, the Media Stream Player window will be opened: Click on the double-arrow button to have the application display more detailed information about the audio stream s and access to manual codec mapping.
