I am experiencing the same issue. After 1.4 I can't get any sync going to my android phone. LAN only. Have not and will not enable any outside systems (dht, tracker). As far as the "internet connection" I do have wifi on, obviously. Will start to test which feature will enable windows/android syncing. Ok, so I disabled LAN encryption and that did it. I had a feeling it was going to be in that ballpark because on the android app there is a section in the settings about "Identity" which I can't edit, set or manage. So as long as that Identity is not LAN encryption does not work which makes perfect sense. So until we know how to set that identity just disable lan encryption. Hm.. Disabling encryption only helped so far. The phone can now see the share but no files are actually ever sync'ed. Man I wish I hadn't updated to 1.4...
