I just added TL-PA9020P Powerline Network Adaptors to my home network.Now when I try to upload from the computer attached to the remote powerline adaptor (upload data across the powerline network) my modem loses its internet connection. The modem is a Telstra supplied FAST5355-A. In the modem's error log I get messages such as:
VDSL connectivity is down port 1
WAN DHCP client (1) stopped
Is there a way to prevent the disconnections? Which device is at fault?
