nup. the DX's do indeed have zippo Wifi.
Well perhaps that's the case. would seem sensible. might be the stupid request to amazon failing. IN WHICH CASE simply add the URL that the DX searches for (it's well documented I forget) in /etc/hosts and make the thing DIE, MUCH FASTER
It's only a guess but I think resolving the DNS and killing it to some localhost would be faster than failing the DNS lookup.
HTH
