iTunes match fails on upload, loops

Thank you Noblehops and rwthelen for figuring out the problem and providing a solution/work around. Apple iTunes Support was no help though we spent a couple of hours together trying and I spent more hours tweaking, deleting, reformatting, etc. I should have known it was a bandwidth issue, but I could not bring myself to believe that slower would be better than faster. Thanks so very much. Now, if only Apple would fix iTunes Match. Sigh.

Thanks so much to everyone on this thread. This has been driving me NUTS for a month. Items would upload in, say, November, although not reliably.

In Dec and Jan, it became unworkable, where the endless loop you've all described simply repeated - never uploading one single item except for the first few hundred kB or so as one of you mentioned.

I NEVER would have thought to throttle down my upload speed. I am a COMCAST customer, which seems to be a common factor, with 10 up and 30 down (measured). Throttled the router down to 2mbps up and EVERYTHING IS WORKING PERFECTLY NOW.

Thanks again so much to all of you.

Yes, Steve is certainly rolling over in his grave. Apple has had plenty of time to address this problem (there are certainly plenty of Comcast customers using iTunes).

It's almost beyond belief that Apple seems oblivious to this huge problem. Very sad commentary on the state of affairs at Apple.

I'm on a Windows 8 PC, and both my apple router and Motorola modem have no setting for limiting upload speed. So I found a program called NetLimiter that allows me to specify exactly how much bandwidth each program uses, or how much up/down my entire machine is allowed to use. This appears to be working as expected. Much applause for the forum posters who suggested this!

ITUNES BUG FIX SERIOUS. ATTENTION APPLE!

Apparently many COMCAST High Speed Internet customers are no longer able to upload songs properly to iCloud. The only solution found is to throttle the upload rate to the 2mbps range. This has solved the problem for all in this thread.

This is a SERIOUS ITUNES BUG and ICLOUD BUG, potentially involving a large number of customers.

If you are able to distinguish COMCAST customers dropping the iCloud service, out of proportion, this bug should be a prime suspect as the cause. We were canceling our subscription until finding this thread.

(I don't expect this to be read by Apple, but it can't hurt to try!) 😉

Does anyone know of a PC application that will do this on Windows 8? My modem is a netgear and doesn't have upload settings.

Check out NetLimiter. I got the "beta" version 4, and that's worked great for me.

Running itunes on Vista I had the same problem with Itunes Match hanging, sometimes with a time out message. Took the excellent tip and my ASUS router had a setting for upload speed set to 750k, changed that to 500k and the problem went away. Big Thanks guys

I'm another person who had this same issue. Signed up for iTunes Match today, and the uploads of songs not available in iTunes wasn't happening. I let iTunes sit for 2 hours before I found this thread. I'm also on Comcast for broadband. And like everyone else, enabling the upload QoS on my router (a Netgear Nighthawk) did the trick. About 1 minute after the QoS was enabled, the upload counter started ticking away. I blame Comcast for blocking this, not an iTunes problem.
