Slow WIFI connection with Mate

Hello Everyone!

I have a TP-link WN822N, and TP Link does provide drivers for linux;however, i do not know how to install them. I downloaded them and unzipped them, but it as files i really don’t know what to do with them… ( MakeFile, Kconfig, etc)
I searched how to use Make files, and i read that i needed to configure them, then clean make, then make, then install make? well i tried all that, but i get errors haha

The reason i want to install TP Link drivers, is because I am having extremely slow wifi connection with Ubuntu Mate. I installed Mate on my Desktop this past Friday, and i have been experiencing slow Internet since…when downloading, i get speeds like 150kb or less, when i should be getting 2.5mb or more…
