I just ordered 2 of the PWR Line Pros to test them out and I'm not able to get them to sync. I tried using different outlets throughout the house (plugging them directly into the outlets) and at this point I just have them both plugged into the same power strip. I have tried holding the sync button for 15 seconds on both of them to reset them and then tried to sync again, held the sync buttons for 5-8 seconds, and then tried to sync again, and I'm not able to make it work. The amber light for searching just keeps flashing for 120 seconds on both ends and never goes solid.
Am I missing something here or are they just broken? If they're broken, is it fairly common for these to not work right away or did I get very unlucky for my first test?
We're an ISP and I'm testing these as a solution to expand WiFi coverage without needing to schedule a cable run. Has someone installed a lot of these that can tell me if they have consistently performed well?
