Can't connect WiFi to Chromecast in bedroom anymore. Just stopped working. The one in my front room still works. Rebooted, unplugged, everything. There's just a lock symbol on my WiFi symbol in settings and just says can't connect. Had them both 3 years, do they ever just stop working ?
Thanks for reaching out. Let's check this further.
A few questions: when did the issue start? What type of Chromecast device do you have? Are there any changes in your Wi-Fi router settings?
Give these steps a try:
Let me know how it goes.
