Why won't my Galaxy S4 connect to my home wifi ever since updating to Lollipop?

[AC Question]

why won't my galaxy s4 connect to my home wifi ever since updating to lollipop?

Everything has been working fine for months with my Galaxy S4. Then, 2 days ago, I updated to lollipop via my home wifi - so it was working just fine. Immediately after updating, my phone won't connect to my home wifi. It It repeatedly tries to connect (says, "Connecting ...") but it never actually connects. It then says "Saved, Secured" under my home wifi network name in the Wi-Fi settings on my phone.
I have tried resetting the phone (including by removing battery), resetting the router, resetting the modem; toggling wifi on/off; toggling airplane mode on/off; resetting router to factory settings; and several other things but nothing works. Any help is greatly appreciated.
