Pixie, have you checked the belkin url in the first post on this thread? (i know you said you've already done a lot of reading, and i commend you for that!) Be sure you also read the part about dsl in that post since you may need to make adjustments at the dsl level (if allowed) Also try the www.practicallynetworked.com
page as it has tons of useful info. http://www.dslreports.com/forums/all
has lots of info on various routers
I dont remember if anyone has previously posted info specific to setting up a belkin, but you can try using our search feature, set it to all forums and all posts and use belkin as the search term.
