New WiFi Repeater Range Extender w/ Directions Box 4 Computer & Cell Phone Use.

This was om a list on internet as one of the best. It doesnt work fir me as my security camera set only works with their repeater or using 2 cameras as a repeater. Not taking less..this cost alit mire than I have it listed for. It days 1200 Mbps Specification with the 300 Mbps checked...have no clue what that mumbo jumbo even means.
