Thanks bill001g. Can you elaborate, or, know where I can find exactly how-to set this up properly? I just want to extend my wifi a bit further out past my patio area for a solid strong signal and reliability. Currently, I right at the spot where the signal drops off quite noticeably, within a matter of just a couple of steps. I was hoping the repeater/ extender setup using my old RT-AC66U would solve this. I don't wish to create more issues by not setting this up correctly.
