I want to use Time Capsule(2012) to extend the wireless signal from other brand's AP
Unfortunately, the Time Capsule can only "extend" a wireless signal from another Apple router. It is not compatible with devices from other manufacturers if you are trying to "extend" using wireless only.
If you can connect the TIme Capsule to your Asus router using an Ethernet connection, you can configure the Time Capsule to provide more wireless coverage that way
