why does losing a wifi connection or using flight mode break service discovery until power cycling the adapter or rebooting?
Steps to recreate issue :
Run Dns-sd -B "_services._dns-sd._udp.local." ~Returns all Services
Turn on Flight Mode
Discovered Services Removed
Turn off Flight Mode
Services not added back in
Close cmd prompt
open new cmd prompt
Run Dns-sd -B "_services._dns-sd._udp.local." ~returns no services
restart Bonjour Service
Run Dns-sd -B "_services._dns-sd._udp.local." ~returns no services
Disable Wifi Adapter
Enable Wifi Adapter
on windows 10 Run Dns-sd -B "_services._dns-sd._udp.local." ~Returns all Services
Issue also occurs on win 8 with the same hardware.
Code is c# , dns-sd is being used to test the system , the following open source packages have been tested :
zeroconf c# https://github.com/onovotny/Zeroconf) ~ Same issue
Mono-zeroconf c# (https://www.mono-project.com/archived/monozeroconf/) ~ same issue
mdns browser (https://chrome.google.com/webstore/detail/mdns-browser/kipighjpklofchgbdgclfaoccdlghidp) ~ Works , I have no idea why.
On some setups (router - adapter - os) there is no problem on others it just doesn't not work over a connect / reconnect.
On a failing setup I have found 1 usb wifi adapter that will work out of about 20.
one of the non working adapters has a device property called Radio on/off , if I use this instead of flight mode then it does work.
there is no real consistency in why it doesn't not work , no errors , warnings or any key issues
