Android phone does not reconnect back to wifi after leaving and returning to home.

[Android Central Question]

I am using an Android OPPO F1 and have set up my router recently as a wifi extender via cable. Almost everytime I leave my home and come back, my phone cannot connect back to the router. It will state 'connection denied'. However, after I restart my router, I can connect back to the router with no problems. Why is that?
This does not happen to my Windows laptop or desktop as-yet turning them on at home and they reconnect just fine.

Welcome to Android Central! I've always had problems with wi-fi extenders (which is why I recommend a mesh router system instead). Is it required to have the same SSID as your main router? If possible, see if you can change the SSID for the extender to something different.

If you're using a router as an extender, read Wired Bridge with two WAPs using the same SSID. You may have the system set up incorrectly. (There are many more incorrect ways to set things up than there are correct ways, so unless you've done a few of them that worked, the odds are better that you did something wrong.)
