You can connect a USB cable to the Wi-Fi Adapter and run a terminal emulator to see all kinds of debug prints. You’re welcome to try that and see what it says though I’m not sure it will be helpful. I look forward to hearing whether the remote works. I assume it does, and the problem is just that it’s not reconnecting to Wi-Fi.
How long would you say the Wi-Fi is down? 8 hours or so?
