Have been using the extender for quite a while. No problem until recently these 2 days. Connected after that it stops connecting. When go to settings on iphone to connect again to the 5G ext network, it shows incorrect password. Keyed in the correct password but it does not accept. Have also upgraded the firmware to the latest also cannot solve the problem. Have also tried reset factory settings and redo the whole process still does not solve the problem. When off and on the extender, it starts to connect back but only for less than 5 minutes. Any ways to solve this issue?

If you are referring to the password to get into the extender itself through the web admin portal then make sure you use admin as the user name and do not use a custom name
Also recommend using the same password as for your router admin login to make things easier.
Apart from that only thing else I can think of it doing a factory reset on both the router and extender
Try using the same ssids and passwords so all your devices can reconnect automatically
