Gave Humax my equipment details, here is their smart reply.:
Hi,
Unfortunately we only support the use of official Humax WiFi dongles and cannot guarantee other brands of model will work with our products. We also unfortunately cannot guarantee that WiFi dongles that have worked in the past, will work with any new software updates that we release.
My apologies for any inconvenience caused.
Best Regards,
AndrewG
