I just ran a speed test, and here are the results:
Wired on main, unmanaged, gigabit switch: Download (114.28) Upload (4.36)
Wired to Aruba 800 10/100 controller: Download (90.96) Upload (4.27)
Wireless, on a 5GHZ Aruba AP-121: Download (73.27) Upload (4.27)
I think the speed drop between the wired controller and the access point is well inside the range of being able to handle pretty much anything I can throw at it, but sure enough even when I was running the speed test over wireless and wired through the controller, I tested Google and Youtube again and they were as slow as ever, but wired through the main switch seemed to be fine
