TP -Link powerline adapters randomly disconnect

It seems to be an issue reported several times. But TP-Link do nothing to fix it.

My advise, don't buy tp-link powerline.

If you have the specific bug where you can replug the adapter to fix the connection, you can stop the connection from dropping by sending data over it at regular intervals. One way to do this is to ping your default gateway (home router) at regular intervals.

You can add a Windows scheduled task for this:

1. Go to Administrative Tools > Task Scheduler > Create Basic Task...
2. Enter any Name and click Next >
3. Select When I log on and click Next >
4. Select Start a program and click Next >
5. In Program/script: enter ping and in Add arguments (optional): enter -t <address> where <address> is the IP address of your default gateway
6. Click Finish
7. You can start the task immediately by going to Task Scheduler Library, right-click your created task, and click Run

For Ubuntu:

1. Go to Startup Applications
2. Click Add
3. Enter any Name and in Command: enter ping <address> where <address> is the IP address of your default gateway
4. Click Add
5. Log out and then log back in to start the task

A few things to try that weren't mentioned:

• Upgrade the firmware (US or UK).
• Plug both powerline adapters directly into the wall outlet. Don't use them on a surge suppressor, UPS, etc.
• Troubleshoot any sources of interference by unplugging as many devices in your home as possible (particularly those on the same circuit). If the problem goes away, start plugging them back in until you find the problematic device.
