Check the Internet speed once Spotlight & such have caught up. Then unplug onne USB tging at a time to see what is causing it.

If the Hub is really self powering another Hub isn't likely to hep.

In System Report>Hardware>USB, how msny mA are being ised & how mant mA available?

Have you tried simply changing the location of this hub to see if it will make any difference for Wi-Fi connectivity?

If you have, and it didn't, then it may be possible that either the hub or the provided power supply is emitting enough EMF to affect your Mac 's wireless connection.

You may want to check the return policy from where you got it, and consider getting another brand. I suggest hubs from OWC. They are considerably more expensive than your current hub, but you really get what you pay for.
