Make that modem/router.
Manuals are always a good place to start.
Visit the support pages:

Feed in your model number and check the documentation for your hardware.
Check the section in the manual
View or Change the Modem Router Wireless Channel
You may have done that already. I can't tell from your message.
I mention it because Netgear gave up on supplying paper manuals and CD versions some years ago and people sometimes miss the downloads.
