Need proprietary drivers, so with just dranstecken times there is nothing

The plan was to replace my old D-Link Stick which can only 2.4G - approach: external antenna + many good reviews 5G + Support = must be good indeed - reality: nope.

After most diverse replacements I came to the conclusion that the D-Link in not so ideal placement brought twice the performance itself. 5G (via good ASUS router) was far worse than 2.4G, although the latency was better. Nobody around here also uses 5G.

The question is therefore, what all this. Good delivery from Amazon, although eingedepscht, product must be returned but. This is not improving like this.
