Hello Everybody,

I recently installed Wireshark, when I open wireshark it shows "No interface found" while I have a TP-LINK's TL-WN823N(USB wireless adapter) connected.

How do I setup or add the interface to the wireshark interface list. Help is greatly appreciated :)

What does the Help -> About window in Wireshark report? (Please copy and paste the text, rather than trying to post a screenshot.)

I executed the command C:\Windows\system32>sc start npf

and it returned me(text below)

[SC] StartService FAILED 31:

A device attached to the system is not functioning.

Was the USB adapter plugged into the machine at the time it was booted? If not, what happens if you reboot the machine while it's plugged in and then try to run Wireshark?

Yes Harris...adapter was connected! rebooting is not fixing the issue :(

Depends on os and many other factors. Reboot, as well.

with WinPcap version 4.1.3 (packet.dll version 0.10 r12), based on libpcap version 1.0 branch 1_0_rel0b (20091008)

This indicates that you are using a very old version Npcap's wpcap.dll and the latest version (0.10 r12) Npcap's Packet.dll. I can't tell what's the driver's version. In another word, your Npcap installation is broken. A possible cause is that you uninstalled Npcap with Wireshark still opened. So an old wpcap.dll is still in use by Wireshark and not deleted.

I suggest you close all Wireshark windows. And reinstall Npcap's latest version again, if there's still issue, then send the DiagReport to:

Running on 32-bit Windows 7, build 7600, with locale English_United States.1252, with WinPcap version 4.1.3 (packet.dll version 0.10 r12), based on libpcap version 1.0 branch 1_0_rel0b (20091008)

You seem to be running npcap which is currently considered experimental for use with Wireshark. npcap may have been installed directly by yourself, or as part of another installation e.g. nmap beta.

If you wish to continue with npcap, you'll need to get support via the npcap Github issues page.

If you don't require npcap, please uninstall it, reboot, and re-install Wireshark allowing it to install WinPcap 4.1.3, and then post back here with the result.

So what indicates that it's Npcap? It says it's "libpcap version 1.0", which sounds more like WinPcap (based on an older libpcap) than Npcap (based on a more recent libpcap).

packet.dll version 0.10 r12
