Windows startup is 20 seconds slower when TL-WN722N V3 is plugged in
Windows 10 is stuck in the login screen for about 20 seconds before mouse or keyboard works when USB WLAN adapter TL-WN722N V3 is plugged in. The green light starts blinking about 3 seconds before keyboard becomes functional.
Things I have tried which have NOT helped:
- Install latest driver (version 1030.29.1102.2017, date 18.7.2018). In web page the published date is 2019-04-18.
- Hard code IP address (instead of using DHCP) and disable DHCP and WLAN Auto-config services.
- Connect ethernet cable
- Disable legacy USB support in BIOS
- Try different USB ports
- Disable "Allow the computer to turn off this device to save power"
Things I have tried which have helped:
- Disable the WLAN adapter in "Control Panel -> Network and Internet -> Network Connections". But of course then it doesn't work! Re-enabling it takes about 24 seconds.
Motherboard is MSI B450M Mortar MAX. Windows version is 1909, build 18363.657.
I don't see anything interesting in the system log (in event viewer). There is a 20 second gap of log entries.
Everything works as expected after the 20 second delay OR if I connect the adapter after Windows has started.
I reinstalled Windows last week, so it's pretty fresh.
