My sony expria e1 will not connect to broadband router phone shows authentication problem

Your WiFi Broadband Router has a password that is needed to be entered on the mobile. Tap the WiFi Icon, it will show you the WiFi Router Name. Tap on that name and it will ask for password. If it does not ask for password then it means there is No Authentication, and the mobile must connect to the router automatically. You will need a Data Service Provider to connect you to a Broadband Internet Link.

Had same problem - said signal weak although strong on other devices, and hung on authenticating.

Cordless phone on base unit was beside wireless router. Moved unit and turned off phone. Problem disappeared, and signal showed strong.

Please clarify the d-link model number.

In setting up the phone and connection, you need to know a passphrase that was set up for the router. If you get that wrong, you have an authentication problem.

Your mobile has a built it Wireless Fidelity or WI-FI module enabling to catch ata over wireless networks.

By turning ON your wi-fi, it will search wireless network along the nearest location of yours. Once you found a network(s), just open it and wait until established and connected,but some authenticating connection never allows you to connect because it needs a password encryption.so you won't able to patch the network if you do not know the code.

If you have a broadband installed at home, you need a wireless router that can supply internet connection using your mobile phone via wi-fi,just easily series the broadband connection thru a wireless router and also add encryption like WEP key to ensure you are the only one catching the connection.

please state your broadband if any so that i can guide you the procedure in installing your wireless router connection.

If you have some questions, don't hesitate to reply cause i will glad accomodate any comments.

Thank you for visiting FixYa..

What is your wireless security / authentication type? Change the type to WPA 2 and try.
Hope it will work.

Thanks and have a good day.

Depending on the make or router, the internet light may just signify that that an internet signal is detected and not that it is actually authenticated to use the internet. If you can get to the diagnostics or log page of the router and look for 'Chap authentication'. If this has failed then the username and/or password is not being accepted by the ISP.

Try resetting the configuration of the router by holding the reset on the back for about 10 seconds, then reprogram the authentication settings.

Please rate this helpful if it was!

Make sure that the wep password is correct.

change channels to 1-6-or 11.

check is to make sure you are NOT using "IEEE 802.1x authentication for this network."

You can find at setting under "Wireless Network Connection Properties" and then under "Authentication" tab of your network properties.

This particular authentication method is periodically logging you off the network and re-authenticating.

Check the adapter in device manager to make sure that windows is not shutting the adapter down to save power.

Cordless phones and wireless ethernet cards use overlapping frequencies.As a test, you can unplug the AC cords from all the cordless phones in the area and see if it helps.
Also, check and see if the usb ports and the device are being shut down to save power, in device manager.

Please see my response to this question. Your university's connection is most probably a LAN connection, so you'd need to follow the instructions as if you had a cable internet connection (unlike DSL, a LAN connection and cable internet connection don't require authentication with the ISP).
