Samsung Galaxy S3 — Wifi - security type unknown

I had the same problem, but I fixed it this way:

Settings > Wi-fi > + Add Wi-Fi network > Enter the network name in Network SSID, select the security type ( WPA/WPA2 PSK) and enter the password if it is not an open network, and then tap Connect.

I hope I I have helped.

This works. Thank you very much for your help!

Hi Isabella,
I am having the same issue, my work WiFi shows security type unknown and I cant connect to it now though it used to connect previously.
When I go to Settings -> WiFi , it shows the listof WiFis and signal strengths ( including my Work WiFi), but I cant find the option to Add WiFi network as you said.

Same issue here!
I've googled it and nothing that can save me :c

scroll to the end of your list of conections its at the bottom.. it took me a few min to fig out.. its there and it works

This is a shot in the dark but here goes.
That WiFi signal could be accessible only by certain device numbers, and your device number is not on the list!
Or
If you have your cookies shut off and your device number cannot be seen. That could stop you from using that signal.
Just a thought I had!

Settings > Wi-fi > + Add Wi-Fi network > Enter the network name in Network SSID, select the security type ( WPA/WPA2 PSK) and enter the password if it is not an open network, and then tap Connect
