R7500v1 5GHz help....?

I have the latest version of openwrt for my nighthawk x4. And i have downloaded drivers for the 5ghz. So how do I install the drivers so I can use 5ghz because the firmware didn't came equipped with the 5ghz drivers. I don't want to go back to stock netgear firmware so I need help. I don't have a computer right now as I don't know how to flash through ssh. Somebody mentioned about such kernel from backports that i don't have the link towards. I'm just a beginner and I'm not no where near advance. Somebody help me?

Please don't double post.
