Can anyone please tell me if a new firmware version is available for the Ariva 52E?

If there is a new version available for this receiver, does anyone know if it fixes WiFi Connection problems as well? Also, will my channels that are saved/antenna settings remain, if i upload a new s/w?

I'm hoping this will fix my WiFi problems (have the Ferguson WiFi adapter W02), which give me 'connection failed' when i try to view downloads from Web TV (and YouPorn doesn't work).

I'd really appreciate some help woth a guide to uploading the software, as my receiver is new, and i don't want to ruin it.

hope someone can help
thanks
