My Android phone's connection to the internet via my Powerline device (I have a TL-WPA8730 Kit) seems sluggish. It is strange because when I do a speedtest the speed seems fine, I get around 30Mbps download speed. But when I open an app and open pictures in the app, it takes ages to load. I'm talking minutes. As soon as I switch off the wifi and go on mobile internet, the picture loads in a second, even though I only have 2 bars on the mobile phone signal. I have tested this many times by closing the app and reopneing with mobile only. The app loads faster with wifi off.

When i connect a Dell laptop to the powerline extender via wifi there is no issue. I also have a pc connected via ethernet. I have this problem even when all thes eother devices are powered off and only my phone is connected to the powerline. I have actually noticed this issue for many years, with different versions of Samsung Android phones. I get internet via a BT Home Hub with a speed of around 65Mbps. When I connect the phone via wifi to the main router there is no problem. It only seems to be when I my Android phone is connected to the Powerline extender. My powerline extenders are cloned with the same settings as the router.

For years i have lived with this, when i am in my room just switching off wifi and going on the phone mobile signal, but I need to get a powerline extender for another room, so I now want to get to the bottom of this issue or else try another brand and see if that helps. Any advice greatly received.
