Only my phone cannot connect to only one specific WiFi Ok so Ive seen plenty of problems where peoples phones can't detect any WiFi networks, or if a particular router can't connect with mobiles, but I don't have any of those problems. My problem is very specific: My office WiFi is not visible on my phones WiFi list, but everyone elses phones can connect just fine. However, my phone can connect to every other WiFi with no problem. In fact, every other WiFi (21 of them) on my laptops list is also visible on my phone. It is only my office WiFi which is not visible. This happened after a WiFi upgrade a few months ago. Does anyone have any idea what could be causing this?

Android version: 6.0

Phone: Moto G 2nd generation
This happens quite a few times. According to my observations. I have noticed the main reason behind this is entering a wrong key (password) to the wifi network which makes it temporarily disabled from the wifi list of the phone. Try forgetting the network which you may have connected once and reconnect to the same network with correct password.
