This error happens to us about once a week. We've not been able to solve the problem.

Here is some further information:

  1. The problem occurs on my computer but not my wife's computer.
  2. Resetting the wireless router doesn't help.
  3. Resetting the modem might help but we're not sure.
  4. Restarting the computer does not help.

Here are some of the error log details:

Best Answer

Issues with windows networks can often times be fixed by resetting winsock.

Run the following form the command prompt 

netsh winsock reset
netsh int ip reset

If that does not solve the issue, you can try a windows 8 refresh

If the issue continues, download the latest network adapter drivers from the manufactures website an install them.

If after all of that, the issue still occurs, contact Lenovo support, or take the laptop to a computer repair shop for further diagnosing.
