Have you compared the web interface of a Telus-provided SE567 to that of a factory-issue one, such as the interface depicted in the manual you can (with some difficulty, last I checked) download from the manufacturer's site? It's like comparing English to Japanese.
> I have enabled Show icons for networked UPnP devices in My Network Places, out of curiousity, and in order to do that, a large amount of software is installed that seemingly enables UPnP.
That essentially triggers the steps listed in kb941206 as well as one other step they missed mentioning, which is opening the correct ports on Windows Firewall, as I mentioned. Out of curiosity, when nothing else worked, I disabled and re-enabled the same setting, but that didn't help either.
> An icon then shows up for most routers (ones that are UPnP compatible) in My Network places, but it does NOT show up in Network Connections. Only mentions the icon appearing in My Network Places - it does mention other icons possibly showing up in My Network Places.
I don't mean to be argumentative, but FTA: "For the UPnP architecture to work in Windows XP, the Internet gateway device must appear in Network Connections." (That statement occurs just above where the article states: "Also, the router must appear in My Network Places.") Also, if you note the first screenshot in the article, an additional item (named "Internet Connection") is depicted in Network Connections, of type "Internet Gateway"; noting the second screenshot, a router is shown in My Network Places.
In the case of the computer I'm working on, the gateway is listed in My Network Places, but not in Network Connections. Network Connections on this computer only shows one item (name "Local Area Connection" and with type "LAN or High-Speed Internet"), matching the second shown in the article's second screenshot, and corresponding to this computer's on-board NIC.
I'll try also activating the "Universal Plug and Play Device Host" service as recommended by the DSL Reports article you linked. (Although, that doesn't seem to make much sense semantically, since the computer is supposed to be UPnP client, not a host; but then again, it is a Microsoft product we're dealing with, so I guess somewhat senseless names are to be expected.)
