I've got another box in the house that I get all the channels with the same line and I run it on wifi with no probs.
I done the channel scan on the x6 and it just seems to be it that I have the problem with. The other box I'm using was able for me to update with a channel list from aj and I seem to get everything with that.
Even when I unplug the other box from the lnb it doesnt make any difference.
