Hello! I have a wired network with the PA7017P kit (AV1000) which was working great! I bought 1 WPA4220 (AV600) which I wanted to pair with the PA7017 connected to my router. I used pair button and it connected very fast with very good bandwidth. I connected it with ethernet to a PC. But when I turned on the PC connected to the second PA7017, internet was dead. I had a bandwidth of 0.3MBPS! At first I thought that something was wrong with my internet connection but when I powered off the WPA4220 and restarted the PC connected to PA7017 everything was back to normal. I powered on WPA4220 again and same thing happened...

What is wrong?

Thank you in advance!
