Ah, the joys of Wi-Fi, the magical airwaves that somehow make our modern world go 'round. Or crash and burn. Depending on the day, of course.
So you're wrestling with a case of Dr. Jekyll and Mr. Hyde Wi-Fi? Your device is giving you mixed signals—like a bad date that can't decide whether they're into you or not.
Here's the deal: It's likely that your TCL LinkZone modem supports multiple encryption methods—WPA, WPA2, WPA3, etc.—and can negotiate the best one depending on what the connecting device supports. When your device is giving you a "Weak Security (WPA)" warning, it's basically side-eyeing your network for not being up to snuff. But in the list of Preferred Networks, it might be aspirationally listing all the types of security the network could offer in a perfect world.
So, which is true? Probably both. Your modem likely supports WPA2/WPA3 but might default to WPA or switch to it when it connects with a device that can't handle the fancier stuff. Time to dig into the settings and tell your modem to stop living in the past. Stick to WPA2 or WPA3, and let's make that "Weak Security" badge disappear, shall we?
