hi everyone I used wireshark a few months ago on my laptop and it worked fine. recently I reinstalled it again but few seconds after it starts, the laptop disconnect from wifi networks even if I dont start monitoring and it's not possible to connect again but as I close wireshark, it reconnect again! I reinstalled wireshark and drivers multiple times and even used a different adsl modem, uninstalled zonealarm firewall and antivirus but the problem persists. here is the last pockets just before wifi disconnet:

Do you use WinPap or npcap?

And, regardless the answer to the previous point, do you get the same issue if you double-click a previously saved capture file, so that Wireshark doesn't start from the welcome/dashboard screen but immediately opens a file?

Dear sindy, WinPcap 4.1.3 is installed by wireshark and yes it disconnects few seconds after I open a saved file

I'm out of ideas then. In the past I had the same experience with a particular version of npcap (and seemed to be the only person affected in the universe), and the reason to ask about starting Wireshark on an existing file was that if started without indicating a file, Wireshark captures on all interfaces so that it could draw the realtime traffic graphs. So my next step would be to uninstall WinPcap and try again to ultimately find out whether Wireshark itself or WinPcap is what cannot live together with your system.

good Idea man! I uninstalled WinPcap and started wireshark! now it cannot identify any interfaces but the wifi disconnected again few seconds after starting wireshark!
