1) TWRP is a custom recovery, not a way of rooting.
2) Neither TWRP nor root have anything to do with connecting. You (or the app or program you used to root) must have done something else - and that's preventing connecting.
What did you use to root? Did you flash a rooted ROM, or run something else? (If it was a ROM, it's probably defective. If it was something else, we can't even make wild guesses without knowing what it was.)
