I would make a batch file with the following commands to run, then run as administrator-
netsh wlan delete profile name="xxx" interface="Wi-Fi"
(where xxx = duplicated wifi name, copy/paste for all duplicate instances)
netsh int ip reset
netsh winsock reset
shutdown -f -r -t 5
It's definitely a Windows issue. On the machines that you're seeing this on, is there OEM wireless software installed? On Dell laptops there's a ridiculous OEM program called "Dell Unified Wireless Suite" that has wreaked havoc for me on occasion. I always remove any OEM wireless software and just force drivers only install.
