Default wifi/mobile net just disappeared

last night i reinstalled my phone, with the newest neatrom and PhilZ-cwm6-XWMS2-MOT-5.15.9. im pretty new to this, but all was fine. but this morning, everything working, and then, from nowhere internet just stopped working on the phone, both wifi and mobile internet. if i look at the icon in status bar, it looks like i have internet, but its not working. any ideas?
