I've just tried to upgrade my readynas to the new 4.1.9 firmware but I encounter the same problem that last time with 4.1.8. I've got a message with a checksum problem...
I've tried the remote or local update: same problem. I've read several users had the same problem, but I never succeed in resolving mine
...Does anyone have some advice ? I just precise that before 4.1.8 I never encountered this problem during upgrade.
