I would like to use the stick on the ISIO K4 receiver. It is apparently recognised, at least I can see all available networks in the network settings of the receiver. But logging on to my WLAN constantly fails, the receiver reports "Connection not possible". No connection can be established via WPS either. The router works perfectly. There are no MAC or IP filters or similar. I have several other devices running on the network, from AV receivers to gaming consoles and mobile devices, all of which work. Technisat support was unable to help me and recommended that I send both devices to them in Germany. Has anyone here had similar problems and got them solved? If so, how? Thanks for any input.
