If the searching above didn’t work out, determine the network’s hardware configuration. Figure out whether there is a trouble with the networking hardware or hardware device drivers. My experience when troubleshooting user problems, is that it is often solved by updating device drivers and system updates, and occasionally static configurations on the network card.
The final step in procedure is to test communications. Perform a series of tests that can help you pinpoint the nature of the problem. The test might be something like:
