One of the Wifi networks on S5 has started reading not in range

[AC Question]

This is a work Wi-Fi connection and no one else at work has this problem. So it appears to be an issue with the phone because it has worked fine up to this point.. The other Wi-Fi networks on my phone work fine. Have tried several suggestions with no luck including forget network and reinstalling, changing security settings, removing battery, ect. Any suggestions would be appreciated...
