I was wondering if there was already a way to connect through WIFI with the Mod-Duo ?Maybe using a USB - Wifi Key ?
no, not yet.
the next version should have working bluetooth though.initial tests have shown it to work quite nicely, just a bit slow to load resources. but once it's cached (after you loaded a plugin once) subsequent loads should be much faster.
I solved this by connecting the MOD to the router (the DSL wifi modem here also has a USB port). It needed a bit of tweaking, but this way I can move around with the laptop. The MOD has to stay put in that case.
