My Wi-Fi access point is in "WPA/WPA2 mixed mode", which allows devices to connect to it using either WPA, WPA2-TKIP, or WPA2-AES. My Apple® smartphones and tablet computers are warning that my Wi-Fi has "weak security" because of WPA and WPA2-TKIP. I don't see the issue with the presence of WPA and WPA2-TKIP, since I am always connecting using WPA2-AES. Is my mixed mode Wi-Fi insecure even if I always connect using WPA2-AES?
The mode is only "mixed" if devices of different wireless generations are connected on the same access point. So your network key is as secure as your weakest (WPA) version device. You can't run WPA attacks on a WPA2/3 client because it's not using WPA even if other devices can or are on that network.
So the answer is yes but with some important distinctions.
