AC1900 Rax35 Packet Loss

Hello all, 

Need a bit of help trying to figure out whats going on. I know an Ethernet connection is always better but as is currently it's just not possible. I use a AC1900 Wifi Adapter with a Rax35 Nighthawk Modem and about every 30 seconds or so I get a loss of packet lag spike. It makes FPS (Which I mainly play) Impossible to play at all. I don't know much about networking but I know I'm losing packets because I use a program called ExitLag, I was hoping it would even me out and while it did lower my ping it didn't stop any of the packet loss Exitlag is saying currently just with google up I have had 329 Spikes in connection and 63-68 packets lost. When I'm gaming it's higher and more frequent. I could really use some help solving this!!! It's also recording my max pings between 610-993. q.q
