Wireless adapter under $20 HELP

[fjnfnvd]

I need a wireless adapter (doesn't matter if USB or PCI-E) to help me play multiplayer video games. I would like to have it $20 or under, also my house has a lot of interference. And I have a couple of walls from the distance of my computer and the internet router. I'm getting it not to get better quality internet, but so my PC can get internet. Motherboard:GIGABYTE GA-H61M-DS2 LGA 1155 Intel H61 Micro ATX Intel Motherboard. I don't know if this matters but my router's brand is D-link and I also live in Australia, so prices will usually be higher. Also my operating system is Windows 10.

For $20, I think you can still buy a pair of rusty tin cans and some string.
