No problem and understood. Very tough to tell what is happening in your specific case, but the image running on the ICX (switch or router) should not really matter here. With that said, It may be worth a look. I would advise doing a couple tests to figure out where the issue lies:
1) wired laptop plugged into icx > test speed
2) wired laptop plugged directly into modem (bypassing ICX) > test speed
3) wireless client (preferably newer device and with good signal) > test speed
That may give you a better clue if something is happening within your house. It could also be something ISP-side as well in which case that is a non-Ruckus issue.
