Gadget, Yes, it seems to be exactly the same with mine too, i got a email saying to upgrade firmware on my router. (Dir-628) so i accepted it and downloaded the firmware and uploaded it on. But now, it seems to be the shareport light on the router shuts off, but the shareport application could tell you that there is a device connected to it...I connected my printer to it (Samsung ML2010 Laser) But it never can connect, i also try to let shareport find the folders of the printer but never seemed to work, i believe this issue i happening with everyone, hopefully Dlink would get a new firmware asap! So we can use our shareport that we payed for.
Good Luck, if you seem to get it working, can u give me a hand then? Thanks!
