I have one 7392:7811 Edimax Technology Co., Ltd EW-7811Un 802.11n Wireless Adapter [Realtek RTL8188CUS] The rtlwifi/rtl8192cu driver turned out to be flaky for this device, usually it stalls after a few minutes. Searching the web it seems this is well known and everyone uses a patched vendor driver (https://github.com/pvaret/rtl8192cu-fixes.git). The rtl8xxxu driver ssems to work stable (I tested the git branch rtl8xxxu-nextgen, commit 2e23469d74d7). However, thoughput is less than one half compared to the vendor driver. FWIW, rtlwifi seems to be a bit faster when it works, but thoughput fluctuates a lot and eventually it stalls. (Tested with iperf TCP in both directions.) >From dmesg: [21725.096068] usb 1-2.1: RTL8188CU rev A (TSMC) 1T1R, TX queues 2, WiFi=1, BT=0, GPS=0, HI PA=0 [21725.096072] usb 1-2.1: rtl8xxxu: Loading firmware rtlwifi/rtl8192cufw_TMSC.bin [21725.096179] usb 1-2.1: Firmware revision 80.0 (signature 0x88c1) Thanks, Johannes
