PPPOE is very old school dial up connections, and bridge is to bridge between your cell and another device (not gain access to wifi). Did you read the manual? Did you google the model and Manual? I did and unless it is a 'unlocked and altered phone' it plainly says
Turning Wi-Fi on and connecting to a
Wi-Fi network
Touch > Apps tab > Settings > Wi-
Fi from the WIRELESS & NETWORKS tab.
Set Wi-Fi to ON to turn it on and start
scanning for available Wi-Fi networks.
Tap the Wi-Fi menu again to see a list of
active and in-range Wi-Fi networks.
Secured networks are indicated by a
lock icon.
Touch a network to connect to it.
If the network is open, you are asked
to confirm that you want to connect to
that network by touching Connect.
If the network is secured, you are
prompted to enter a password or
other credentials. (Ask your network
administrator for details)
The status bar displays icons that indicate
Wi-Fi status
Now if your connecting, as you indicated before, but your still not getting through on the wireless, and when you go to a different hotspot (Starbucks, etc.) and the same thing occurs, then your phone is defective and you need to speak to your cell phone provider for support (a fix they can provide or provide a replacement). Again the test for this is when you go to a open hotspot, do you have the SAME problem? If not, then we need to stop looking at the phone then look at the settings of your home wireless as the problem. Make sense?
