Powerline adapter kit is slow

[darael]

I've installed a TP-Link TL-PA7017P powerline adapter kit for somebody and the speeds are awful.

One of the two adapters are installed at the front of the house, where the Virgin Media SuperHub 3.0 is. The other adapter is at the back of the house, connecting to a PC. On a 250Mb VM subscription, we're seeing ~4Mbps speeds in Speedtest, sometimes increasing to 30Mbps. Wi-fi speeds are far better in the same room, thanks to a wi-fi booster, seeing speeds nearly maxing out the connection.

As somebody new to these powerline adapters, I just want to know if they have a training period and if they will get better in time? Is there anything that can be done to get more sensible speeds? For example, changing brand/model of adapters?

Due to the layout of the house, practically every room downstairs would need to be drilled into before being able to hit the room upstairs. I should have said that's it's rented accommodation too, so they're going to have consult with the landlord before punching holes everywhere.

Just posting an update really. I had more time to look at things today and we've decided that the best way forward is to return the powerline adapters and use the wifi. I've given the 2.4GHz and 5GHz networks different names so 5GHz network can be identified and connected to, giving the speed needed for downloading and 2.4GHz network can be used for stable connections.

While it's not the perfect solution, it works and everybody seems to be happy. There is a wifi booster on the landing which gives nearby uses almost the full speed of the broadband and the PC also connects to this as it's not that far away, being nearly halfway along the landing.

Thanks once again to everybody for their input. I'm just trying to get the best practicality from an exhausted budget this month.
