Time to check if your IP and Subnet addresses are in the same ballpark. Look into your network properties page for this info. You did not say whether a router is involved.
Help!
I have a desktop and a notebook "connected" in a wireless home network.
The wireless connection icon says the notebook is "connected" to the network, and the signal strength is "excellent".
I used to be able to access the wireless network from the notebook, but suddenly now I seem to be not allowed to access it anymore!
The shared internet connection does not work in the notebook anymore, and if I try to access the shared folders of the desktop, I keep on getting the following error message in the notebook:
"(network place) is not accessible. You might not have permission to access this network resource. Contact the administrator blah blah. The Network path was not found."
WHAT CAN I DO to access my own network?
I already tried connecting from the "wireless network connection - properties" dialog box, but no success.
Thanks a lot in advance
