How do you change d-link's broadcast channel?

I have a d-link WBR-2310, and for some reason my wii has a hard time connecting to it. Sometimes it connects, majority of times it refuses. Now I heard from different sources that changing the broadcast channel will work. But I can't seem to find the option to change it. Its probably a stupid question, but where do you go or how do you change the channel?

I assume you already know how to get into the routers settings? IE in your browser window, enter the router's IP address (usually "192.168.1.1").

Anyways, From the top select "Setup", then on the side you'll see "Wireless Settings". From here, unclick the "auto channel selection" checkbox, then select a new channel from the channel dropdown. Then click save settings.
