Other devices can connect to wifi but computer doesn't

Can someone help me regarding this issue, our dorm bought a PLDTHOMEFIBR wifi and its working properly for my phone. However, upon checking on my computer, it shows it has internet but it will not load sites then now it is showing "No Internet" even they are connecting on the same WIFI, what fix could I use to resolve this?

I attached a photo for additional info of the WIFI
