I have an iPhone 4s, I reset all my network settings and I cannot connect to password protected networks (say incorrect password, when I know it is correct) but I can connect to non-password protected networks. Help?

Oh, and this all started because I couldnt do a back up. One of the suggestions was to delete all your old back ups because there could be a bug. So now I cant do a complete factory reset because I have no backups and I would be screwed. I did a "reset all settings" because I read that could be a solution too and thats how I got to the point where I cannot connect to my wifi now. I also tried to just do a "reset network settings" still cannot connect to my password protected network. Oh, and I still cannot backup my phone!!!

thanks appletini... I am going to try to go back into ATT tomorrow to see if someone will talk to me then... and then next is I drive the 30 mins to the apple store...

Thanks!! I appreciate the advice

The phone wont let me backup at all, either thru wifi sync nor by cable...

And I did attempt to manually input the network id and password, I have ATT DSL and spent about an hour on the phone with them making sure it was not a router issue... My GF has a 4 and it connects just fine. It is hard for me to believe it is a hardware issue on the phone because I can connect to unprotected wifi networks just fine. The security type is WPA and I've been connected to my home network for over a year with no problems until today.

My fault for not explaining all the way...

I originally couldnt back up the device thru wifi sync nor thru the cable. One of the suggestions was to reset your network settings, which I did. Still couldnt back up the device, so I wanted to try backing it up to the icloud, I couldnt because I wasnt connected to my wifi at home. When I attempted to connect to the wifi it gave me an incorrect password, but it is correct. I have also been successful in using non-protected wifi networks. So yes, there are 2 problems, I do not know if they are related or not, but I would probably be able to back to the iCloud if I can use my network at home...

Also, I have googled my issue, and seen this as a recurring problem for several people... However, there is no solution to be found, I would feel that apple would address this issue since it seems to somewhat of a common problem... I have scheduled myself for a genius bar appt tomorrow

So I went to the genius bar, which helped and didnt help because I had a pretty good idea what I was going to have to do. They said it was a software issue, and the most likely solution would be a reset all settings and media... but since I didnt have a backup that made it tough, however, I did have contacts, pics, etc synced with icloud which those are my important things anyway. Thats where the genius bar helped out, they pretty much allowed me to do factory reset without the worry about what I was going to lose, since they explained where I had certain information. My apps were lost, but were on my itunes, so it just took a few mins to restore that. Pretty much the only solution so far is factory reset. Just make sure ur contacts and photos/videos are synced, and everything else can be recovered, even without a backup, because itunes stores a lot of it. I also, did a manual import of my photos/videos, just in case, but I didnt need it. I am hooked up to the wifi at home, with a password no problem. Now I have to see if I can back up the phone after I set it all back up to how I like (personal user settings), and if I have an issue, I'll make a new thread since that is a different problem.

I was able to both do a wifi sync backup as well as a cable backup. So when I did a reset to the factory settings whatever bug was not allowing me to do a backup went away, same as the bug that was not allowing me to hook up to password protected networks. Now, were they related, I dont know. I was hooked up to the wifi just fine before I encountered the backup error. But in any case, all my issues were resolved in one fell swoop. Thanks for the help.
