Under Network Adapters - Broadcom 802.11abgn Wireless SDIO Adapter - I disabled it then enabled it. I have done above steps and success several times before. However, not sure why i have encountered same issue and it didn't work anymore. Eventually, i have found my ASUS T100 been attacked by malware in registry and system32 folder that diagnosed by Advanced SystemRepair Pro. The malware files are following: c:\Windows\System32\igfxdev.dll c:\ProgramData\SetStretch.VBS c:\ProgramData\SetStretch.exe c:\ProgramData\SetStretch.cmd I have deleted these files and some registry contain malware. So you can try download Advanced System Repair to scan u laptop and fix it accordingly. i found this website in other forum http://en.forumsbeitrage.com/quot-ready-boot-quot-error-0xc0000188.html Hope this will hep u solve your problem!
