How can i fix my wifi problem on my SAmsung Galaxy Ace IIx. My wifi was working fine until 2 days ago when my phone got disconnected randomly. I tried to reconnect but my phone says authentication error occured. I am entering the password right for sure and i even tried restoring the phone to factory settings but no help. What do i do? Thank you.
If it's your own wireless network you're having difficulty with, unplug your wireless router until all the indicator lights go out, then plug the wireless router back in. Make sure all the lights come back on and ensure that your router is visible from your Ace 2x by performing a Wi-Fi scan. If the Ace 2x "sees" and connects to your Wi-Fi network, disregard the next step. If not, on your Ace 2x, "forget" the network you are trying to access, re-enter the necessary credentials and try connecting to your wireless router. Let us know if that corrects the problem.
I tried all of that and i even did it many times but no luck. The phone says authentication error again. Also the phone is not connecting to any wifi network, it is having the same problem with every wifi i try to connect to.Also, will koodo replace my phone? I got this phone on Boxing Day of 2012.
I had the same issue on my Galaxy S8. It will connect for a minute and then it was disconnected automatically and display a message "Unable to connect" but the WiFi is working on all other devices. I tried this wifi authentication solution but not work for me, It works well for my friend.
