New to this forum and the CPE 210 Range extender 

I recently purchased this unit and went thorough all the proper steps to set it up as a repeater to my camera approximately 150 feet away. 

After setting up the unit and configuring the repeater functions - it now causes my internet connection to go down - 

I unplug the CPE from my router and the problem goes away - my internet works as it should - 

I have this hooked up as: 

Router to POE adaptor

POE adaptor to CPE 210 

Any help appreciatted
