WiFi was working fine on Friday dead on Saturday. I checked the Events log in Properties and found a Device install requested @ 4:05 am (Device PCI\VEN_168C&DEV_001B&SUBSYS_500111AD&REV_01\4&38a322f7&0&28A4 requires further installation. followed by Device Migrated, Device Configured, Device Started (Driver Name: netathrx.inf). @ 4:20 the Device was deleted @ 4:20 Device not migrated (could not be migrated.) There were several iterations of this sequence as I disabled then enabled or uninstalled then reinstalled but the result is always the same. no WiFi at all. My computer is a Lenovo Tower H405 with all the software up to date.
