Thanks for the answer.
It has FW 2.09 version. I have shareport 1.20, after first shareport setup my printer worked fine. I use to turn off the router when I don't use it. The next time I turn on the router shareport couldn't recognize my printer. To solve the problem I entered to the router USB settings and reconfigured to shareport, after router reboot shareport could find my printer again.
I've been reading and realize I'm using and old version of shareport so I want to update it.
Regards,
Fer
