Why Internet Connection got lost everytime my phone goes into sleep mode?

[Pierre_Pommier]

I have a Symphony i10. It was working for me fine but only one problem i couldn't solve. When my phone goes to sleep mode the data connection will automatically disconnected. I was trying to connect my phone with internet by USB Data Tethering. Do you guys have any solution of my problem?

You will need to check your connection settings for the tethering.
Many times things like this will default to disconnecting when the phone is not being actively used.
