Authentication problem but broadband connects on computer............

[theoportoman]

Hi

Yesterday my Sony Xperia failed to connect to my broadband for the first time. It found the wifi but wouldn't/couldn't connect. However, my computer that uses the same wifi and password to connect is fine. I have tried re-entering the password etc but it makes no difference - the phone doesn't want to connect and now I receive "authentication problem" messages on it.

Any ideas ??

Thanks

Have you tried rebooting your network gear?

Welcome to Android Central! hallux's idea is what I would try first. You can simply unplug the router for 10 seconds, then plug it back in again. If that doesn't work, see this guide for more ideas: http://forums.androidcentral.com/am...roubleshooting-wi-fi-connection-problems.html
