After several tests, I'm a little confused about my download speeds. I used the same TV show on all platforms from the iTunes store. I'm using Roadrunner with my account set to allow 1.875MBps (actual has been over 2MBps in testing). I'm using a first generation Time Capsule with 7.4.1 firmware as my hub. The Time Capsule is configured for N only, 2.4GHz, channel 1 and the AppleTV and MacBook are connected via a solid 130 Mbps (16.25 MBps) connection with a great noise-signal ratio. (I use a Linksys for a separate b/g network on channel 11).
I'm using a MacBook, an AppleTV, and an iMac G5 all with the latest software/firmware updates.
All systems report the same amount of bandwidth regardless of wireless or wired of about 2MBps using the RoadRunner bandwidth tool and Speedtest.net.
When I download the show from iTunes on my wired iMac G5, I get the expected 1.85 MBps or better.
When I download the show wirelessly from iTunes on either the MacBook (easy to measure) or the AppleTV (based on download time), I'm getting about 0.250MBps max.
When I connect the MacBook directly to the TC via ethernet cable, I get about 1.8 MBps - slower than the iMac, but still in the expected range.
All repeated tests on the MacBook wireless or wired show the expected throughput of 1.875MBps or better.
Why are the wireless downloads slower when all bandwidth testing shows the wireless and wired bandwidth is equal at 1.875MBps, my wireless connection appears solid based on the tools I have available at 130Mbps?
I would think that if there is more than adequate bandwidth available (math says all devices should be able to easily sustain the 1.875MBps), that the iTunes download would be the same for all 3 devices. The tests were run several times on each device to make sure the numbers were repeatable and reduced the likelihood of error caused by other sync'ing to MobileMe, Mozy, etc... eating up bandwidth.
Might be better in a TimeCapsule or Networking forum, but I only really notice an issue when downloading content from iTunes that I plan to use on the AppleTV. Sorry if this is a stupid misunderstanding on my part.
