I bought a no name POE switch in 2014 and now it does not always work doing a un-plug and re-plug gets it working again for awhile but when your not home there is nothing i can do. I paid $75 for it, i also have a tp-link that i paid $157 for in 2015 and it still works so far....I need 6 POE ports. Just wondering what people here use? There is a BV-tech that is only $64 I don't know if it's worth spending double to get another tp-link. My POE switches are exposed to extreme heat/cold one is outside in a water tight box and the other in my garage.
