I need a new receiver and was thinking to get the Xtrend Et8500. However I noticed that:

1. This receiver does not include onboard Wifi
2. Xtrend state that wifi is optional via usb but they dont't seem to sell a wifi dongle

If I get this receiver will I be able to use any wifi usb dongle which is compatible with other Linux receivers? Is there any particular brand and model which has been tested and confirmed to be working with the Et8500?
