Resulting in serious impairment to 3 stars is the "PoE" connection:
It works only the supplied adapter, the device does not support PoE standard.
Hence the name PoE is also misleading because it does not work with it.
Who, as I want to use a PoE switch will be disappointed.
This is a point deduction.
The second point is deducted because it is nowhere indicated in Manual or in the description.
This is really annoying and would have saved a lot of stress and money. PoE is a standardized method (IEEE 802.3af). This term should not therefore going to be used by TP Link in the description.
Conclusion: The device erlauf lot of freedom and attained by the directional antenna a surprisingly good range. Would it supported genuine PoE, there is easy 5 stars.
