iPods/iPads/iPhones Not Good About Playing Nicely on Wireless Networks
Princeton University has a nice article on their Network Systems website that, in plain language, explains why an iPod does not play nicely on their network (or other networks too). I'm disappointed that Apple has not fixed this, because it really is not good behavior.
In the process, they also explain how a typical wireless network (and often a wired network) works. It's good reading, and helps to explain why one sometimes encounters wireless networks that just don't seem to work properly. Often, I'm suspicious it is because the wireless network has run out of "leases" (connections) for new users.
Besides explaining this, it is useful for anyone with a wireless network to understand the principles of how it works for troubleshooting.
