If your router doesn't have these channels available, it's probably because you are in a region where these channels are illegal (like california) and will cause interference to other services.
DO NOT operate your router outside of its allocated channel space!
If we can afford a $3000 console, we can spring for a $25 router that can use the 5Ghz band.
As if we don't have enough hassle from the FCC etc. taking away our wireless mic frequencies, you don't want to provide fuel to provoke a dumb kneejerk reaction like legislation banning modded router firmware or worse by using a public forum to promote using it to operate illegally out of band.
