Hello,

 

Several times a day I lose Internet connection on devices connected to powerline adapters with ethernet cable, which isn't great, as this was supposed to be stable connection as opposed to wi-fi. I get great speeds that don't fluctuate when it works but the disconnects are frustrating.

 

I have two devices that are on wired connection, a desktop computer and a TV. They are connected to different powerline units (I have two kits) in different rooms.

 

In case of the computer when the connection drops I unplug the cable from the back of the PC, plug it back in and that restores the connection almost instantanously. The adapter is in my light of sight and the three LED's are always on including when the connection drops.

 

In case of the TV when, for example, watching YouTube a buffering spinner animation appears and then after what feels like maybe a minute (it's a long pause) the connection gets restored. I never tried the unplug/plug 'fix' that I do with my PC on the TV but I suppose it would do the same trick as with the computer.

 

Nothing to do with my router as wi-fi is always available. I'm with a different internet provider now, upgraded to fibre broadband, and that has not improved things. It's firmly and squarely problem with the powerline solution.

 

As a side note, some colleagues I spoke with who happened to use TP-Link adapters complained about the same stability issues too. Some got fed up and got rid of their powerline set-up altogether replacing it with mesh etc. and 'solved' the connection stability problem this way.

 

So apart of throwing out powerline adapters is there any way to fix this problem? I like my powerline set-up when it works so it would be a great shame if there was no fix to that.

@Mistadobalina 

Hi,

Thank you very much for your patience.

Sorry for the delay.

Please refer to the following suggestion to have a look:

1. turn off the power save mode on the adapter:

https://www.tp-link.com/en/support/faq/2018/

2. enabled the lower VDSL mode:

https://www.tp-link.com/en/support/faq/2027/

and if possible, please help me check the IP address and default gateway when the computer lost the connection:

 

Thank you very much and wait for your reply.

Hi, Thanks for your reply.

 

I haven't applied the suggested changes yet. First I wanted to provide the requested readings when the issue occurs.

 

These two commands give the same reading when there is connection and when there isn't:

@TP-Link 

 

I have a mac connected to the same powerline unit and it gets disconnected too. I tried to apply your suggestions but your app does not work.
