Great picture quality on the mag256w2 hardwired, but I have found using wireless in another room not as good as my mag254.
I have emailed infomir and they have asked me to send them pictures of signal info. I have both boxes running side by side in my kitchen, the 256 is showing -78db and the 254 -50db.
I will post their reply.
I should have mentioned that both boxes are from main infomir dealers.
