The vendor driver you are using, 
/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514.2012/, is relatively old. My 
patches were for rtl_92ce_92se_92de_8723ae_88ee_linux_mac80211_0010.0109.2013, 
however, since I wrote earlier, I found 
rtl_92ce_92se_92de_8723ae_88ee_linux_mac80211_0011.0128.2013, which you will 
find on the Realtek web site under the RTL8188CE listing for Linux. That one 
includes my feedback to Realtek about the 01092013 version, and it should build 
on mainline kernels through 3.8, but not the current wireless-testing, but I 
doubt that you are using that tree. With that driver, my RTL8723AE got 
throughput of 60-70 Mbps for both RX and TX. I did have an unexplained kernel 
panic while running that driver, thus there might be a severe bug in it. I don't 
know if it is rtl8723e, but that is the only panic that I have had with 3.8-rc4.

The driver for the RTL8188CU/RTL8192CU is a mess. Unfortunately, I am not 
getting musch help from Realtek. For that reason, I am concentrating on the CE 
models. Their PCIe group is more responsive.
