Ok, I have an ipad my mom gave me, sorry, don't know what gen (I think it may be the first ipad air, or maybe 2nd. Model: MF018LL/A). It was a hand me down (She had it lieng around and I had a use for it). It's running ios version 12.1.4. It was doing fine yesterday and then this morning it would not connect to wi-fi (I haven't done anything to it except play Netflix on it, it's pretty much my netflix machine while I do cook and clean). Not my wi-fi as my other devices are fine (I used my ipad mini for netflix this morning and I'm typing/posting this on my mac and they are both on the wifi router I'm trying to connect to). It keeps saying password is incorrect. Not only do I absolutely know I am putting the right password in, even when the ipad mini shares the password with it it still refuses to connect. I looked up the problem and I have tried everything I have seen suggested (reset ipad, forget network, reset network, manually enter in network) other than resetting the router (mainly cause i don't know where the router is in my house). Is there any other suggestions on what to do to fix it? Or am I looking at a possibility that the hardware randomly broke on me?
