Saw this issue today on a guy's 14-inch HP laptop with Intel Core i3-1115G4 CPU. Describing the fix here in case it may help someone else.
Wireless connection was unavailable. Went into device manager and it showed the yellow exclamation mark on the Realtek wireless device. Uninstalled it and Scanned for hardware changes, in the hope that it would install it correctly. No go. The exclamation mark came back again.
Uninstalled it and instead of scanning for hardware change, opened CMD as Administrator and ran the command SFC /scannow
When it finished, it said it repaired corrupted files. Rebooted Windows and on the next login, wireless connection was available like nothing was ever wrong. Kinda surprised that this kind of corruption can happen where it is easy to think that the hardware device has had some sort of serious failure.
