I already using WPA (I think, will check when I get in) but I don't know anything about network channels! How do I find out what that is and how to change it?

The router is actually a NAS drive with wired router built in and intergrated wireless access point. Freecom FSG WLAN Gateway (http://www.freecom.com/ecproduct_det...sCatID=1147649)

If you guys let me know what to look for in the settings, I'll have a nose tonight when I get in - thanks!
