Cannot receive or send email on my home wifi after changing passeord

I recently changed my password.  I went into my iPhone Mail and changed the passwords in the Incoming Mail Server and SMTPs (outgoing mail server, primary outgoing server, other outgoing server).  After this was initially done, I was able to receive and send mail on both my iPhone and iPad at my home using wifi for a short period of time.  Then, it quit downloading mail on both.  I then checked the Security setting to ensure it allowed 3rd-party providers.  Both devices had the box checked.  If I turn off wifi at my home, I can send and receive mail.  I cannot on my iPad.  However, if I’m at another venue, like Starbucks and the like, my mail downloads on their wifi.  Please contact me to help me with this issue.
