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"

My other USB WLAN dongle iwth a Ralink chipset works flawless with my PC and
AP, so it seems not to be a PEBKAC problem on my side :)
Please hit me if you need more information, Thanks in advance

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.

No one had reported that this device used rtl8192cu, thus it is not in the
device tables, nor is it in the USB database as shown by the bare entry in your
lsusb output. Attached is a patch that will add your device to the tables. That
will be submitted to the maintainer relatively soon.
There were a number of changes to that driver that just appeared in 3.10-rc6.
These fixed a number of bug reports on the Red Hat bugzilla as shown in the
commit message for commit 5b8df24. I had built 3.10-rc6 from the mainline git
tree; however, I had not booted it till now. With it, my Edimax EW-7811Un
adapter with an RTL8188CUS chip could connect to WEP, WPA1 and WPA2 APs;
however, when I dug out my Alfa AWUS036NHR with an RTL8188RU chip, it could not
connect to any of my APs. I now need to check the results for the
wireless-testing git tree, which I normally use, to see if there is a difference
in the two trees.

Thank you for your effort Larry,
compiled the latest stable kernel (3.9.6) with your fixed device table, the
dongle is now recognized properly, when the module (rtl8192cu) is loaded.
The connection issue to any AP still remains, with the same dmesg output. I
don't believe that the changes you mentioned in 3.10.0-rc6 are the trouble
makers with this device. I tried many different kernels before (3.26, 3.8.0
binaries from the Ubuntu sources, 3.9.6, 3.10.0-rc6 build from scratch). I
hope you can see some possibilities to fix this problem.
Thank you in advance
Tobias
