Erratic Issues after implementing new wireless AP's

[nomdeplume]

How am i not using the product correctly?It is meant to be an AP or a wireless repeater.

Your post sounds like you have Powerline/Ethernet over Power devices plugged in to the wall, and you also have Ethernet cables from these devices running back to a switch. If so this is not the correct way to implement them. perhaps I misunderstood your orignal post.
