I am encountering web ui inaccessible after power outage or disconnecting to wifi. I need to perform a power cycle for it to be accessible again, I use the ap as repeater mode and the omada app can detect it when I perform a power cycle and can access the web ui also "tplinkeap.net" but when I disconnected or a power outage occur, the problem of accessing the web happen again, I'm wondering what's going on here, is this a firmware  issues or what. does anyone know what's the main problem here? I'm not using any controller I used it as a standalone mode. 

I have internet connection but the only problem was the we ui can't be access even the omada app cant detect it, it will be Temorary solve if I'm doing a couple of power cycle.
