Tivo DOES store partial downloads. Forcing a daily call does not erase the partial download. Note that test calls DO clear out the partial software uploads.
At this point, you should probably take it to an analog phone line and let it complete the download. It typically takes about an hour on a clean phone line. It's difficult to say how long it will take using VoIP -- there's no way to know if the 27-minute call did anything or if the modems were simply renegotiating speeds and protocols the entire time. It does sound like you are making SOME progress.
The wired USB adapter should be working, if it's from the official list of approved adapters for software version 5.0. Does your router give it an IP address? The Belkin F5D5050 gives people the most success. Believe it or not, some USB network adapters are incompatible with certain routers. Keep your receipts.
Unfortunately, after you get the update, there is a small chance you may have problems with your Netgear wireless adapter. Isn't this fun?
