Hello, I'm fairly new to this site so if I've bypassed some other threads concerning this issue I apologize. Regardless, I feel I have unique variation of the general issue that others may be having. Since I'm unable to find a solution elsewhere I figured I would give it a shot here. I recently bought my Galaxy S4 (model SCH-I545) and it has been working flawlessly. I'm always connected on Wi-fi whether it is home or work. On the first try I was able to get connected and have had no issues since yesterday. The router I have is a FiOS-provided box (I can grab model number later if needed). I moved my router so it was off for a bit. Now it seems like I'm unable to connect. Everyone I attempt to it says "Authentication Error Occured." I made sure the WPA key was the same as before. Some other things I tried was restarting my router and forgetting the wifi connection on my phone and re-connecting, but no luck. I've verified that other devices work on my wifi and I've also made sure that I can connect to wifi at work still. Is there anything someone knows that may help with the situation? I'm currently not home, but I'm willing to try different things when I am. I know my way around my router setup just maybe not different settings if that is something I need to do. Any help is appreciated. Again, I apologize if this question has been asked and/or answered somewhere else. Thanks!
