I am not sure where to check so i thought i would ask here.

A while ago, i experience disconnections from my wireless connection, at random, several times an hour. That problem went away on its own. Yesterday, we had a power failure, and since then, it regularly disconnects from the modem. It is only on one computer, mine (obviously).

When this happens, i can open the Network and sharing center window, and click on the red x that appears between the home network and the internet/modem. Nothing appears between the computer and the home network (i mean no X).

That starts some troubleshooting, and although it identifies as there is a problem, once it has checked all that, the connection has come back.

I am using a D-Link and suspecting it was the actual device that was the problem, i switched it with my husband's, since he had the exact same one. No change.

so, i am kind of wondering what i should check for. Any suggestion?
