Default [Q] Weird WiFi issue

Out of the blue, 4 days ago, my phone stopped allowing Facebook, Instagram, and some websites including Google and Yahoo to open (at least using Dolphin Browser).
I have Comcast and nothing changed on that end, my 2 computes work fine, roommate's phone, tablet, computer, and PS4 work fine still.... But just my phone won't load pages in those apps or websites. I figured something got screwy with my ROM (BadBoyz Kit Kat) so I just fresh flashed their latest Sense 6 ROM and finally got all my apps reinstalled, and it's still doing the same thing. When I shut wifi off and connect through Sprint's slow ass 3g, the apps and browser load fine.
Any ideas??
