Hardware Version:
Firmware Version:

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:

 

01.11.2020 08:02:22 Info XDSL

VDSL connectivity is down port 1

01.11.2020 08:02:22 Warning DHCPC

WAN DHCP client (1) stopped

 

 

Is there a way to prevent the disconnections? Which device is at fault?

@bob888 thanks for the information. I did end up posting on the Telstra forum too and someone there explained that TP-LINK powerline adaptors have a setting for reducing interference with VDSL. In my case turning on this setting seems to have resolved the problem. Here is the crowd support answer with more information in case it helps someone else:

@Bowie 

 

fwiw, it is a known issue when using powerline adapters alongside VDSL services.

 

They either coexist happily, or do not in your case.

 

Powerline signal transmitted on your AC ring mains is on same frequency range used by VDSL signals.  ie. The powerline signals are interfering with the VDSL signal.

 

Possibly your phone/DSL cabling into or within your property is installed too close to existing AC wiring.

 

Sadly, there is no quick fix.  Ask for advice on Telstra user support forum.

 

Otherwise, only suggestion is look at alternatives such as ethernet cabling or wireless solutions.
