Let's try to avoid duplicating prior discussions why gamers get wired or where we use powerline networking.

I am a gamer who uses a laptop and a WiFi internet connection to play various multiplayer games. I find that on some days my ping is manageable (about 70-90ms) whereas on others, particularly when other member of my family are using the internet, my ping rises to an average of about 150ms, and can sometimes spike at 1000+. I also regularly suffer from a 20-50% packet loss.
I live about 20 miles away from any reasonably large towns, in an old house with thick walls. My laptop is an ACER Aspire V3-572 15.6".
I'm not very good with the technical side of computers and am not sure how to improve my connection, I have tried a few different suggestions from various forums, such as downloading 'SG TCP Optimizer', however my connection is still unreliable.
I'm considering buying a powerline adapter, but I wanted to see if there were any better options before spending a decent amount of money. However if the only option is buying a powerline adapter I would appreciate any advice on which one to buy.
Thank you.
