Sony vaio wifi bluetooth not working

This is sony vaio i3 sve15113enw series laptop with windows 7, months ago updated to windows 10 and was working without issues. Due to x0000098 boot error had to recover the os with vaio rescue that down graded the os to windows 7. So had to reinstall windows 10. But after formatting c: drive and reinstalling windows 10 found wifi, lan, bluetooth not working. From the taskbar wifi is Turned Off and both wifi, mobile hotspot buttons are blacked off. It does not turn blue on clicking.

On running netsh wlan show interface shows radio status as both hardware off and software off. There is no switch or fn key found to turn on and off in the laptop. The wireless indicator light glow green on system start as usual.

In control panel and network connections both the lan and wireless adapters are enabled but not connected.

In Setting Network Properties, all Ethernet, WiFi, Lan1 and Lan2 show status as non opertional and connectivity as disconnected. Laptop have Realtek PCIe Gbe Family Controller as Ethernet Adapter and Qualcomm Atheros AR9445WB - EG as WiFi Adapter.

In the device manager network adapters show no error other than for adapters PCI Device, PCI Simple Comm. Controller and Unknown Device under Other devices marked error. Uninstalled those adapters and tried install Intel Management Engine Interface for windows 7 and then for windows 8 downloaded from sony official website and restart does not solve anything. The latest for windows 10 from intel website does not open and show compatibility issue The platform does not support. Even right click Troubleshoot Compatibility did not solve it. Most forums suggest this lot.

PCI Simple Comm. Controller - \VEN_8086&DEV_1E3A&SUBSYS_90AC104D&DEV_04\3&11583659&0&B0 - Inter(R) Management Engine Interface

PCI Device - \VEN_10EC&DEV_5209&SUBSYS_90AC104D&REV_01\4&31f9caf8&0&00E1

Unknown Device - ACPI\SNY5001\4&1e69dd36&0

The windows repair option in xp and 7 versions of setup use to fix these kind of issues. But the windows 10 support only startup recovery and uninstall features / updates and is of nouse.

From the windows 10 setup did update installation over existing os that run for more than an hour and even that did not fix the problem.


You need the appropriate motherboard drivers for the system which were lost due to the reformat and reinstall. Windows does not do drivers well at all
