Since the ping worked on the wireless IP, I’d try disconnecting the wired connection, hard reset (unplug power for 10 seconds). After restarting, try the web GUI again through the wireless IP.
I’m not sure how the web-server works on the Hub, but it might be ‘binding’ to one connection (e.g. wired) which prevents any connections via the other (e.g. wireless). This is a wild guess, since I’m only using a wired connection, but I’ve seen similar problems in other network appliances. It’s sort-of first-come, first-serve.
You could also try repeating the steps with only the wired interface connected.
If you have both available, I would think you’d be much better off using only the wired connection. If you have wired devices, you’ll want them to access the Hub via your wireless router.
