Unleashed mode Master AP

Unless you're using it in Gateway Mode, just Unplug it, and your other APs will select a new Master AP.

Thanks for your reply Michael, it is not in gateway mode, they are just working as access point with static IP address which is also a problem to open the GUI because it just takes me down.

I recommend using a Management IP address, that will always take you to the current Master AP.
Works well with static IP address APs.

But in that case, i will not be able to access the other aps?
