Wireless Network Adapter disappeared after Windows 10 upgrade
Hey,
So after 2 failed attempts at installing Windows 10 on an Acer Aspire Z5801 PC, I finally managed to succeed. However, a new problem appeared after installation..
The Wireless network adapter went completely missing. Windows does not detect its existence at all, it's like the PC doesn't have one installed. It doesn't appear in Device manager + isn't listed as an "unknown device". It's simply not there at all.
The wired network adapter is there, but not wireless.
Any reason for this?
Things I tried:
- Installing the driver from Acer's website - I had to select Windows 7 64-bit as the version is all that's available for my adapter.
- I used a USB stick to transfer the setup files to the Acer PC. It said it successfully installed but still didn't appear, even after a reboot.
- Used a USB wireless adapter (Netgear) to see if it was an issue with how Windows 10 handles Wi-Fi - nope, that installed and worked fine.
- Scanning for Windows updates after using the USB adapter. Some updates were found and installed (no driver ones though), but still no Wi-Fi.
In the end, I reverted back to Windows 7 and what do you know? The adapter got recognised again.
The USB adapter isn't a viable solution since it's required by another PC. I just used it for testing purposes.
Card is a Ralink 802.11n (On W7, it says the manufacturer is LITE-ON)
