Anyone got this combination working well? I back up my parents computers using BT Sync. This one kinda works, some things come through but not fast, and sometimes it won't sync at all.

I've tried adding BitTorrent to their firewall (which is done via home network > devices > (name) > game and application sharing). It keeps telling me the port is already assigned - possibly because uPnP is turned on and using that port.

It seems to work a bit better via wired than wireless too.

Anyone got any thoughts or suggestions?
