unBlocking devices from wifi

I am no longer able to connect to my wifu from my iPhone. I logged on to netgear and was able to se that my phones ip address was "filtered" I took it off from that list and whenever I go to connect on my phone it keeps saying the password is incorrect. Is there a possibity someone or something manually went in and added my phone to that list? I question it because my sons dad was messing on my computer and now my phone wont connect but every other device can
 
Hmm "because my sons dad was messing on my computer" - - is that not YOU???
 
Alright I asked about my Internet not for your opinions on my parenting. I guess I should of left the part out about my kids dad but I felt it was important to share that I think he did something. And FYI he's not controlling he's just a pos so excuse me for trying to figure it out
 
Don't think anyone was challenging - - if there's a difference of opinion on who did what and why, then talk face to face and come to an agreement. I for one will not intervene.
