Question [Q] WiFi Problem

Hello guys, i'm passing per a problem with my razr hd (xt925)
I'm using Paranoid 4.4.4 a lot of time, then I don't believe that her is culprit of the problem.This week my wifi stops working alone, and When I try to go to the configuration of the wifi the app crash, the connection some time works but fall a lot. (This just started this week, I never pass per this before)
I hope you can understand my question and If is possible, help me (sorry for my english if anything that I wrote is wrong)
