Why can't I connect to wifi?

[AC Question]

I just bought a Xperia E Dual phone running android 4.1.1 The internet I am using has a WPA/WPA2 password. I cannot connect to internet via wifi. The phone will state "connecting" for around two mins then will say disconnected. I have tried WPS and also have failed. I have tried factory resetting the phone, turn it off and taking out its battery, and restarting modem with no luck. Any suggestions?

Welcome to Android Central! Can you set the router to WPA2-PSK/AES? That's usually the best setting for devices. See other tips here: http://forums.androidcentral.com/am...roubleshooting-wi-fi-connection-problems.html

This is the guest from above. I used the link you gave me above and I have tried those solutions and determined my problem is with the security. Whenever I turn the security off for my modem I am able to connect instantly. I have tried WPA2-PSK (AES) and WPA2-PSK (TKIP/AES) and I am unable to connect to the wifi with both of those options.

Although it's a much older security protocol, try changing to WEP (if available).

Have you checked if the router's firmware is up to date?

Thank you very much changing to WEP has solved my problem!

Glad it works! I wonder if this is because the Xperia E is a 2 year-old phone, but that's still not that old ...
