Why can’t I see a computer on my network Windows 7?

On Windows 7, go to Network and Sharing Center, change Advanced Sharing Settings. Turn on network discovery for whichever network you’re connected to (i.e. home, public, domain). Although I wouldn’t recommend you turn it on if you’re on a public network.

Can’t connect to another computer on my network Windows 7?

Fortunately, Windows 7 comes with a built-in troubleshooter that you can use to repair a broken network connection. Choose Start→Control Panel→Network and Internet. Then click the Network and Sharing Center link. Click the Fix a Network Problem link.
