Why do I get a weak security warning?
iPhone 7 Plus, iOS 14
Because you have weak security from your internet service provider, likely because your router hasn't been updated in a long time. See this link for guidance --> Recommended settings for Wi-Fi routers and access points - Apple Support
Thanks. This and some research on the TPLink support page made the "weak security" message go away. This was a new WiFi6 router to replace my ancient (> 10 years) Airport Extreme base station that finally died. It never gave me the "weak security" message so I guess it used WPA2 AES encryption by default.
I'm glad you've got it sorted.
