Just an update. It seems my router now has the latest firmware update. Unfortunately, even though I tried to reconnect the printer using WPS, it doesn't seem to be working.
Another thing is, unfortunately, I do not have the USB cable which is why I am trying the WPS setup.
Yup, tried the regular cable-less setup (that I think it does via the computer), and the WPS... they both didn't work 😞
dumb question... did you get the page that asked for the network id and password?
