    I tried plugging in an external drive to my router and using it as a time capsule. I've used file vault on it also and because of this, the network can't read the drive.

    Does this issue become fixed if I use an Apple router?

    An external disk attached to a router will only work with Time Machine is the router supports the Apple Filing Protocol (AFP) network specification.

    Even, then what you are doing won't work. When you encrypt a networked Time Machine backup drive it does not use FileVault encryption, but rather is creates and encrypted sparse bundle disk image in the drive and saves the Time Machine backup inside that encrypted image.

    Assuming you have a router that supports AFP and will work with Time Machine, you will need to reformat the drive to standard Mac OS Extended and then start a new Time Machine backup with encryption selected. That will create the new, encrypted sparse bundle format you need.
