Wi-Fi issue

So my 8x had been connected to my Wi-Fi the other day just fine and now it wont connect to it it keeps saying it can't connect. I haven't had a chance to go anywhere else with Wi-Fi to see if it's my internet or not but I was wondering if anyone else gas had this problem if so how did you fix it?

Once at my grandparents. Kept telling me the password was wrong even though I had already connected that week. But a month later it decides to work.
