The changes in 3.10-rc6 *fix* many problems. They are not the source of them.

Using the wireless-testing tree, my RTL8188RU will connect to a WPA2/AES AP. It 
authenticates and associates with WPA1/TKIP and WEP APs, but there is no data 
throughput. To me this indicates a problem with the wireless keys. I have no 
idea (yet) why some chips are different than others.
