samsung j111f ace j111f won't connect to wifi/internet

My phone stopped working after a (successful?) Try to install twrp. So I downloaded a firmware after checking the region and model. I found about 4 updates so I downloaded the latest one. I didn't check the baseband version. I installed it using Odin and everything went fine till I realized wifi doesn't work: it won't connect to any wifi hotspot when it's in dhcp. It connects when I choose static but Internet doesn't work. Mobile data and Bluetooth tethering work fine though.
Even after using samsung switch and installing the correct firmware with the corest serial number it still can't connect to wifi. Please help!
