How do I update new Firmware fir my Netgear RAX43 router from my laptop?

[alaina2]

I have the RAX 43 Nighthawk router & need to know how I can update it from my laptop computer. The Nighthawk on my Android cell phone does not function properly & I can't do it even though my cell phone is connected to Netgear WiFi. I want to know how to update Firmware on my Laptop instead. Anyone know? Thanks
