If I have an Epson beamer (TW-7100), do I have to rely on this thing for WLAN? Why not use a better quality and cheaper HDMI to WLAN adapter?

In any case, it's an impertinence that many Epson beamers don't have WLAN already integrated, but that you have to buy this part instead. In any case, the alleged Bluetooth function does not work for me - as has already been posted in many comments.

Accepted Answer

The wifi works with it but that's all. The picture transmission rate is crappy and therefore not usable, so I used the cable again.

Answer

As a warning, you can't watch films with the adapter, the transmission rate is too slow. It is sufficient for powerpoint slides or other single images. In general, it is difficult to transfer films wirelessly without the audio delay. I had bought the adapter https://www.microsoft.com/en-us/d/new-microsoft-4k-wireless-display-adapter/8zhwmx8c1wn2?activetab=pivot:overviewtab but it also has microrukler and the audio is not quite synchronous, so in the end there is only the good old cable ;(
