The Network Issue
I've been using this scale a while now and when it works, its very smooth.  No hiccups.  Both my wife and I are using it and it is properly uploading our weights and body fat percentage calculations as expected.<br /><br />However, if you are struggling to get this connected to the internet I can tell you from extensive diagnostics exactly what the problem is.<br /><br />The Network Issue:<br /><br />The Aria does not respond to ARP requests on the network.  If your DHCP server does not remember the IP-MAC association when it hands out the IP address, this scale will likely not work.  From what I can tell, most routers do remember this.  However, some routers, such as those by Zyxel, do an ARP request after they serve up the IP address with DHCP.  Since the Aria ignores the ARP request, the router will have no idea how to contact the Aria.  Thus, you will never get it to work.<br /><br />The only workaround is to get another router.  I had another router lying around and put it on my network.  The end result is the Aria is getting a double NAT address.  Still, it all works.<br /><br />Aria technical support was very helpful and worked with me for months trying to diagnose the issue.  In the end I figured it out myself.  I sent an email to them explaining the issue, but I got the impression nobody exists at Fitbit capable of comprehending this.  They probably contracted the software out and have no way to fix it anymore.
