I tried at least wireless-next but the adapter isn't showing up.
Where to get more log files and stuff?
Isnt this adapter good supported by the rtl8192cu driver or where is the problem?

For the mainline kernel to work with 802.11n-only APs and to reconnect after an initial try, your kernel needs the following patches:

Both of these are in wireless-testing, and were just merged into the mainline kernel. In addition, they were merged with the 3.0 stable tree today.

Both should be in wireless-next, but as I recall, you were not able to test with that tree.

With the updated mainline kernel, the link is stable and performance is acceptible with netperf TCP_STREAM (TX) at 20.5 +/- 4.8 Mbps and TCP_MAERTS (RX) of 21.7 +/- 3.8 Mbps. These numbers are not spectacular, but they will do.

I tried the latest git repo from git://git.infradead.org/users/linville/wireless-next.
Same story here.
After disconnecting to the network, I have to reload the module only then networks are seen.
