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

     The driver fails to clear encryption keys making it impossible
     to switch connections.

     rtlwifi: rtl8192su: Fix problem connecting to HT-enabled AP

     Bug #42262.

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.
