At my wits end, added two new plugs one works one doesn't
Got two new plugs connected one no problem, the other finds the wifi network but won't connect to it. I only have the 2.4GHz band active, the password is simple, I've tried factory resetting the plug, restarting the phone, connecting to the hotspot on my phone (says it can't). I have several tapo plugs and lightbulbs that won't connect now, sometimes it says can't connect to wifi sometimes that the password is incorrect. I don't understand what the problem could be, wifi security is WPA, I've also tried WPA/WPA2 but that didn't make a difference.
