Hi,
Thanks for posting in Q&A platform.
Before we go further, I would like to confirm the following questions:
- If the Windows device which should sent MDNS query was used wired network adapter, whether the MDNS broadcast can be seen on the other devices?
- “But when I change some properties in the windows system-settings for the wifi card suddenly I can see the queries also on other devices but only for a short time.” In this scenario, may I know what kind of properties of the wifi network adapter did you change?
- If the Windows device which should sent MDNS query can access to Internet with the wireless network adapter?
- You could try to disable windows firewalls to test if the issue can be resolved.
- Is there any 3rd party antivirus software which may block the traffic from the application layer? If yes, please try to disable the 3rd party antivirus software to test if the issue can be resolved.
Best Regards,
Sunny
