I have an HDpro-16 dual wifi, however with the firmwares from december my mediaplayer can´t find a wifiee signal anymore. It simply cannott see any signals in the PA screen under wireless connections in setup. When I put back the firmware from 28-10-2011 then i can find the signal again and i Can connect to my network again.
sooooo, can you tell me when the next firmware update will come out and if this problem will be adressed????

Hope to get a reply!
