I have a dlink DIR-615 wireless router. For some reason when I have a connection wired or wireless through this device, my bandwidth is at about a fourth of what it should be. Both upload and download speeds are effected. Im pretty sure it isn't the modem or the ISP because if I connect my laptop directly into the modem, my speeds are perfect. Is there a setting on the router that I need to adjust? I change my wireless key as well so I know that nobody else is on my connection.
