Hi, I've recently bought a TP-Link TL-WN8200ND USB WiFi dongle, it uses the Realtek 8192cu chipset. After several attempts with different kernels (starting with 3.2.6) and compat-wireless drivers, I'm still running into the same problem. The device can successful scan for networks in reach, but cannot connect to any of them, regardless the encryption (tried every mode, including no encryption at all). At the moment I'm using the kernel release 3.10.0-rc6 and the device is still not recognized by the "rtl8192cu" driver module without manually setting the device ID into the SySFS "echo "2357 0100" > /sys/bus/usb/drivers/rtl8192cu/new_id" here is the output of "lsusb" Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 004: ID 2357:0100 Bus 002 Device 003: ID 0c0b:b159 Dura Micro, Inc.
