A few things to be aware of from personal experience :-
The usb ports on the Humax can be 'inconsistent'. My edimax dongle wasn't recognised at all by the port on the front but the back one is quite happy with it.
Depending on the placement of your kit it may be necessary to use a usb extender cable to get the dongle into a clear spot for wireless reception - I did.
Ensure that your router is broadcasting your SSID. If not, the connection will be lost every time you put the Humax into standby.
Other than that, read the many other posts on this forum to do with the Edimax dongle - that's how I found that lot out!
