I can fix the router to get connected to the laptop wifi but for roku i might try to get it conected if that is fine with you.

is the netgear connected to the isp modem and is turned on

i have no much experience for roku you can try it your self however if the wifi router starts working then you can configure it your self.

i will give some input from my side as well.

how do you turn it on to 5G then

reset the router to factory default first and then upgrade the firmware then try it will definately work.

i will give you steps

To reset your router to factory defaults, use a pen or paperclip to press and hold the Reset button for approximately 15 seconds at the back of the router you will see a tiny button indicated as reset button, press it down until the light blinks. The router power should be turned on. Release the button and wait for the router to reboot.
