Today I've accessed my modem configuration at http://10.1.1.254 to change my wifi password.

[AC Question]

Everything went well until I go the the settings. I actually wish to change my SSID name but i accidentally pressed the interface status and maybe I enabled or disabled something. When I try to disabled it back, suddenly my wifi connection lost and I cant do anything. After that, my wifi connection was like 'not in range' all the time. I've turn off my modem and refresh everything include my phone but nothing happened. I've no internet connection edit everthing on my modem configuration settings, so I've registered an internet top up in my mobile phone and tried to enter the same link like before http://10.1.1.254 but suddenly It stopped because they say the link waiting was too long so I can't enter that link and solve my problem. Is there any other way for me to solve this? Please help me.
