There's a bunch of dead links on ETC's pages.
http://community.etcconnect.com/wikis/products/irfr-how-to-setup-your-wireless-network.aspx doesn't work anymore.
All of the links from http://www.etcconnect.com/Support/Consoles/Eos-Family/ and http://www.etcconnect.com/Support/Networking/ lead to http://www.etcconnect.com/Error.aspx?aspxerrorpath=/Templates/Product.pb.aspx
There's a bunch more dead links, but those are the ones I found when trying to find the first article.
