Wireshark 2.5.2 Win64 Hangs During Startup

I upgraded my Win64 Wireshark installation to one of the automated builds, 2.5.2, and it hangs now during startup. It will eventually come up but it hangs for 30-to-40 seconds on, "Finding local interfaces' portion of the splash screen.

Can anyone articulate what Wireshark is trying to do there and why it's taking so long? I only have three interfaces defined on the system (Wired, Wireless & one for a VPN adapter that isn't running at the moment).

If I uninstall the 2.5.2 build and go back down to 2.0.16 it works fine. If I go back up to 2.5.2 it hangs again.

Wireshark tries to read information from the interfaces at startup. Possibly your VPN interface causes it to wait for some timeout causing the long delay. If you activate logging it might be possible to see if this is true. As some work has been done in this area it would be good if you used a recent automated build to test.

I've been having this issue too for about a year and updating to newer versions did not fix the issue. I did find if I opened Wireshark again after it hung on the first try the second attempt would load fine. I found this response on the old forum and it solved this issue for me. After following these steps I was finally able to load the new Wireshark version without issues.

"This is generally a symptom of an issue in WinPcap, the mechanism used to capture traffic on Windows. Wireshark uses WinPcap at startup to query the list of interfaces that can be used for captures.

The actual issue has never been resolved, but uninstalling Wireshark, uninstalling WinPcap, if it remains, ensuring that there is no copy of npf.sys in %WINDIR%\system32\drivers\, reboot, and then reinstalling Wireshark (installing WinPcap when offered) usually does the trick. Make sure you run the installer as Administrator, it should do this automatically, but if you don't get asked for permissions, cancel, then right-click the installer and select "Run as Administrator".

I found this response on the forum by @grahamb on

The odd numbered versions are development snapshots, so YMMV. But you're in luck, a new maintenance release of 2.4 (stable) was put out, and a new stable series, 2.6, is just around the corner. You could try out the release candidate of this series.

OK, so this is strange.... I upgraded to Wireshark-win64-2.6.0rc0-6-gb8ad0997 on Jaap's suggestion and now it's working!

I figured I'd grab some logs anyway as this would be interesting (Ander's suggestion) but while I can set the option (Edit --> Preferences --> Advanced) to open the console 'ALWAYS' the log level is grayed out. Am I doing something wrong or do the RC builds not permit verbose logging? I'd paste a screenshot but I lack points so I'll just tell you that the console.log.level has Status=unknown, Type=Log level and Value=28. I wanted to update it from 28 --> 252 based on what I saw here ( I even tried running from a bat file with a:


option but nothing popped up.

Anyway, for now the RC build is working so ...(more)
