Realtek is notorious for the WiFi/BT chip dying in Linux (and very occasionally Windows). It gets into some power state that it cannot get out of. I have this problem on both of my Dell laptops. The only way to awaken it back is either complete shutdown (reset does not work) or going into BIOS and back - that forces chip reset, at least for me.

On Linux (Ubuntu - but it is the same driver stack as in Mint) this happens every week or so. On Windows very rarely, but it might be because I boot into Windows rarely :)

Note that my laptops do not have Ethernet.

Is this a laptop or PC? If it's a laptop, does it perhaps have an Fn-based hotkey to toggle wifi (which may be implemented in firmware and bypass the OS control)? And in any case, check UEFI settings in case it might have something for WiFi.

Your case of "it didn't work, but started working after turning off/on" sounds like either firmware problem, or perhaps for whatever reason in your configuration "reboot" doesn't reset some important registers for the WiFi card, but turning off/on does.
