I have bought AIS FIBER package coming with VDSL2 HG180 router. When accessing Home Gate page from http://192.168.1.1 to change default password "aisadmin" on "admin" account, this becomes impossible to do. Default admin username and aisadmin password exposed to the territory of 200 m around my home are unacceptable, if do not say more. Please help. Tried to change it from Win 10, Linux, Android, Safari, Asus, Chrome, Firefox without success.
