At the minute, no, VIX does not support wireless...
The advantages of VIX over DE image, is that it has a newer enigma/oe, has newer drivers that support media playback better from recordings (and some enhancements for mkvs etc, but you'll have to check vu's website for what the enhancements are) and supports xmltv & .dat for epg data... Oh, and I've found it runs a lot faster than dream-elite image, and suffers less with hanging (i.e. cogs constantly whirring)...
