Today I bought and set up a brand new 3 Unit Deco M5 Mesh WiFi Whole Home System.
Apart from the Android Phone I have the TP-Link App installed on, (to set up and control the system), I cannot connect any of my other devices to the Mesh WiFi Network... when I try, I get a message saying that the password I have entered is incorrect (which it isn't)
However, when I turn on the Guest Network, which has no password, all of my devices connect to the Mesh WiFi Network just fine (and to the internet too).
The Network isn't secure when used in Guest Mode, so if I can't get the System to work as advertised as a pasword secured network, it's of no use to me and will be going back to the retailer for a refund.
What is causing this false "Incorrect Password" message and how do I fix the problem?
