Connect android tablet to internet via ethernet I am using an android tablet at my work place. For some weird reason, WIFI has been disabled in the tablet. The only way to connect to the internet is via ethernet. 
At this point, I have a USB-Ethernet adapter. I am able to enable ethernet and connect. I even get an IP address assigned to my tablet. 

But, the problem is, I am unable to access the internet on the tablet. When I try to open any application that requires connectivity to internet, I just get the error message "This application requires a working data connection".

Not sure if this is relevant, but I checked the file "sys/class/net/eth0" and it says "up".

Can someone help me out here? 

Thank you ..
i had the same problem. EBay app told me the solution. My date and time were set manually in 2011. I set the good time and date automaticly and now my apps have access to internet.
