Windows 10: Windows 10 Wireless adapter Code 45

Hello everyone,


I have a one-year-old ASUS Vivobook laptop with 64-bit Windows 10 and an Intel(R) Dual Band Wireless-AC 8265 wireless adapter. I have had a recurring issue with the device disappearing from Device Manager. I first encountered this issue last November, but, unfortunately, I am not able to say whether the device was then shown as a hidden device, as it is now. Now, I can see that the error code 45 (Currently, this hardware device is not connected to the computer) is displayed under the device's properties. In November, I resolved the issue by performing a full reinstallation of Windows, which leads me to think that the problem is not hardware-related. I last used WiFi with this device on 12 January, and the device had disappeared when I started the laptop on 13 Jan. No updates had taken place between these bootups. So far, I have tried the following measures:

• Updating all drivers with Intel Driver & Support Assistant
• Updating the Wireless adapter driver manually
• Installing all Windows updates
• Removing the device in order to have Windows install new drivers automatically
• Rolling back to a week-old system recovery point
• Booting in safe mode to perform sfc /scannow, which restored some corrupt files. A CBS log is available, if necessary.
• Running Windows Defender Offline

I can currently use an Ethernet connection as the Realtek PCIe GBE Family Controller is available. Curiously enough, upon booting up the laptop on 13 January, when the Wireless adapter had disappeared for the first time in January, the events tab of the Ethernet device show the following events, in chronological order:

• 19:42 Device deleted
• 19:47 Device install requested
• 19:47 Device configured (oem15.inf)
• 19:47 Device started (rt640x64)

Similar events have taken place regarding all 8 WAN Miniports listed under the Network adapters, but not concerning the Wireless adapter. The Wireless adapter's only event in January is my manual deletion on the 14th. Does this provide any insight to my issue? No other events regarding the Ethernet adapter have taken place before these since the reinstallation in November. Needless to say, I hope that I don't have to resort to reinstalling the OS every three months. Is it worthwhile to have a shop take a look inside the laptop? Could the adapter have become physically disconnected? Is it integrated within the motherboard?

Thank you to everyone willing to devote their time to my issue.

Windows 10 Code 45 on Realtek Network Adapter

Upon booting windows 10 I will occasionally get a Code 45 error on my network adapter. Half the time it works, but the other half it does not. Nothing seems to fix this. This is an on-board LAN adapter made by Realtek. It's detected by Windows but sometimes
gives a Code 45: device is not connected.

This is extremely annoying. Has anyone else had problems with this? Rebooting sometimes fixes this but sometimes it doesn't.
