I have been using a KP303 power strip for a few months without any issues, I've just bought a second one and tried to setup in my network. 
But for some reason, it always fails to connect to my wifi, I've seen that if I turn off the first power strip, then the second one is able to connect. 
Once one of them is connected the other one fails and a red light turns on. Is this a known issue ? Or is there a way to fix this ?
