wifi password incorrect after iOS 8 update
updated 2 devices to iOS 8 using iTunes at home. iPhone 4s and iPad air 2014. Both no longer connects to my home wifi. Both devices keep saying password incorrect when the password is correct. I have a work iPhone 4s which i updated to iOS 8 at work and this work iPhone 4s connects fine to my home wifi network. i am using an iMac at home as our wifi router. The iMac is connected my cable modem through ethernet cable. Have tried powering off the devices, reset network on iPhone and iPad, still keeps saying "password incorrect". HELP!!
iPhone 4S, iOS 8
