rebel_son,

I don't believe the issue is with your router, but rather the Local Area Network adapter settings on your VISTA PC and/or the cable. If the same cable worked OK with your old MAC, then it's probably NOT the cable - unless you're trying to run FAST Ethernet and the distance is such that your cable is too long. You could try a shorter cable between the router and your Vista PC and see if that helps.

Go into your Networking applet under Vista's Control Panel and make sure that your wired Local Area Network connection is "enabled" and make sure the TCP/IP settings aren't configured manually. When you connect this Vista PC to your router, do you get a LINK light on both your PC and D-Link Router? The fact that you can connect to the router on the SAME PC via WiFi and via Wired connection on your old MAC, tells me that the router is properly connecting to the Internet and the wired/WiFi connections are working.

Try going into Vista's Network applet under control panel and temporarily DISABLE your wireless adapter (right-click on device and click "disable"). With the wired connection enabled and connected to your router - see if this allows your wired connection to work. You can always re-enable your wireless connection similar to the way you disabled it.

Try the suggestions I mentioned above - also, please reply with the EXACT make/model of your PC, D-Link router (model/rev), ISP name as well as make/model of your broadband modem,

- John
