Cannot go online-Basic troubleshooting steps
In this post I am describing the troubleshooting steps where you are not able to ping loop back address.
If I am getting reply from loop back address
The possible reasons for cannot ping loop back address are:
1. The TCP/IP suit of the computer is corrupt
2. Ethernet adapter is not working
To fix the issue with TCP/IP suit on your computer use the follwing commands on your computer(at dos prompt).
netsh int ip reset c:\tcp.txt
netsh winsock reset
After resetting the windows socket and TCP/IP suit we need to restart our computer. After restarting the computer we need to check whether the issue persist or not. If still we cannot ping the loop back address the only possible chance is corrupted Ethernet Adapter and we need to change it.
