No, you should not. The wireless Joey is VERY slow, and drops it's wireless connection all to often requiring a plug reboot of the WJ and the WAP...at least once a week. I only have it because of my chosen TV location vs where the coax is.
Well, I cannot say I am particularly interested in a 2 second delay between button presses and the Joey responding. That is about what I have now with my Genie Mini, and it sucks to be honest.
