R30 should be out in the next two weeks
beta testing is going along fine
the main change is to provide a Modem Mode ( if you need to use a better router /wireless do da ) as the super hub is very poor ( no amount of software will fix it )
the other change is to stop reboots
it will be a upload to your current hub , bet you will not notice them do it

this is the change log for the last test for the beta forum
"
Our R30 firmware includes the following changes:
Adds the Modem Mode feature.
Incorporates fixes for lock-ups (where the Super Hub appears unresponsive to traffic and the admin pages are unavailable) and reloads (where the Super Hub would reload for no apparent reason) while under heavy load in 2.4 and 5 GHz wireless modes. These symptoms were caused by a memory leak in the 2.4GHz and 5GHz wireless driver. As part of these fixes we've changed the number of channels available under 5GHz to 4.
Note: 5GHz performance can vary as although it handles interference from other wireless routers better than 2.4GHz it's ability to penetrate walls, doors etc is less. We also recommend you site your Super Hub away from central heating radiators, foil backed wall board and plasma screen TVs if you're using 5GHz as wireless reflections can also cause issues.

BTW
I get 96 mbs wired and 94 mbs wireless ( with a apple Time capsule ) the same speed with the hub alone but the range is as I said before very very poor hence the apple router
