Dell Studio Desktop Computer Windows 7 SP1 Realtek PCIe GBE Family Controller Netgear DG834 Modem/Router I have a problem with my home network that I have been trying to solve for weeks. Hopefully someone will be able to help (thanks in advance). Windows 7 reports that I have no network connection (see image) but I DO have a network connection and I can also surf the Internet. I can see and share files on a Compaq computer running Windows XP from my Dell computer and vice versa (albeit only the Dell’s public folder from the Compaq computer). I tried to share other folders but Windows informs me that I would need to change to a “Home and Work” profile and not a “Public” profile. When I try to do so I am informed that I have no network connection but as I said before I clearly do have a connection. I then tried to fix the problem using the settings in the Network and Sharing Center but when I try to turn on network discovery for the Home and Work profile it does not “stick” but simply reverts back to the “Public” profile. The Windows 7 network map also gives odd readings (see image). It shows the connection to my printer but states that it cannot map to my Compaq computer. Furthermore, it shows that I do not have a connection to the Internet – but I DO. I would appreciate help in sorting these problems out.
