Your HDA should be capable of browsing all the major sites and http://www.amahi.org before doing anything else.
If you do not have connectivity, you may want to check that the settings that you programmed in amahi.org for your network and router match that of your actual network and the router in it. Amahi assumes a regular, typical home network and the settings there should be done to match what you have. The most common error is that the gateway is not set up properly. We have a page on how to [[Find Your Gateway IP]].
Please note that '''only the first NIC/ethernet card (eth0)''' is supported out of the box. If you have two, please make sure you use eth0 for the LAN where your Amahi HDA resides.
