I can'nt get http;//192.168.0.2;2112/ on my browser,am trying to connect my andriod mobile through this connection?

SOURCE: http error $code$

The Error code is a network issue more specifically. If thats coming up when your connected to Wifi it means you're not using the wifi connection. You would have to contact T-Mobile and they may need to remove and re-add the feature to the account which could take up to 3 days to take effect. If you have Total Internet, you can simply change the APN on the phone to internet2.voicestream.com and should hopefully correct the error message as well...
Start > Settings > Connections > Connections tap Manage existing connections, then edit the T-Mobile Data connection and find the APN and change it.

To force wifi to work, try this:

• Set the wifi connection to connect via My Work Network instead
• Then on the phone go to Start > Settings > Connections > Connections then tap on the Advanced tab at the bottom
• Tap Select Networks, and set the top dropdown box to My Work Network and tap OK
• Remember to change that back to T-Mobile Data when you're not using wifi with the phone.
• Try browsing the web again.
