I have a d-link 614 with 3 computers networked onto it. Just to clarify, Are the pcs networked? If so did you follow the Windows instuctions for setting up a network? (creating a network disc, etc) I have this problem somtimes due to network problems. Using one of the networked pcs (i always use the first one with the network setup on to it) go into the control panel an go into network connections. All I have to do is disable and then enable the network bridge, do the same for the local area connection (or USB connection if thats what you are using, if so i would recommend getting a network card). If the internet gateway icon is present and enabled after doing so, the internet should now run. If the internet gateway icon was already present and the internet is not working, disable it and then enable. Just toggle everything in the network connections until the internet is up and running. If this is a no go, its probably a driver issue, install the proper driver. Hope this helps.
