Internet speed woes, need help

Hello, I am on a wireless connection and normally my speeds are about 30Mbps down and 50Mbps up. After about 5 to 10 minutes my speeds go down to less than 1Mbps up and down. And if I reset my wireless adapter it is back to normal for a little while, and then back into the viscous cycle that is ruining my online gaming. What is the problem? And what can I do to fix it?

Thanks

Wireless adapter: Hawking HWUN4 Hi-Gain Wireless adapter
