Another iTunes Match Step 3 upload question
iTunes Match keeps failing on Step 3: Uploading artwork and remaining songs.
It completes steps 1 and 2, but then shortly after it starts step 3, my cable modem acts as if it has lost connectivity (lights go dim), Airport Extreme goes blinky yellow, and then both recover. If they can recover before iTunes Match times out, then the process continues; otherwise, the Stop button changes to Start, and I have to start over from step 1. The last attempt was a relatively big one--I got 67 items to upload.
My cable modem/Airport Extreme work flawlessly otherwise; this happens only during Step 3. I removed and reapplied power to both the cable modem and Airport Extreme, and I restarted the computer. What is going on here, and is there any way to keep iTunes Match from timing out (can the timeout interval be changed)?
Why is it necessary to keep repeating steps 1 and 2? The software should know where to resume. I have 4800 items to upload, and this is going to take forever. Not a good impression.
