My IPS is throttling iTunes Traffic

[dragon499]

I noticed this a few weeks ago - My speed is generally good - both my iPad on wifi and my PC directly wired in, get the advertized 15 mbs, but on my iPad, If I try to download a song, or an app, the speed is a joke. As an example, I was downloading a 10 meg song, and it was going to take 15 minutes! But, when I went to 4g, I got the song on in just under 2 minutes, so I know nothing is wrong with the Apple store.

I'll call my ISP, but I'm sure they will deny the obvious.

Is anybody else having the same problem? Is there anything other than switching ISPs, that I can do about it?

Thanks
