On the TP-Link fibre router, i did setup the username and password for fibre but there's when power goes out and the router restarts, i have to enter the username and password again. This is annoying since i have network cameras i can not longer access remotely without having to physically login to the admin page and re-enter the username and password again. 

My question is, doesn't the router save the username and password for my internet connection and remember this when its powered off and powered on again? Why doesnt it loose the configured wifi ssids?
