TP-LINK TL-WN821N, RTL8192CU connection fail

Postby taska101 on Wed Apr 10, 2013 4:47 pm

Hi Guys,
I bought a TP-Link TL-WN821N USB Wireless Network Adapter. I would like to use with my Desktop PC. The problem is the Network Manager can see the router, but can't connect. Always ask the network key (which is good, I check hundred times...).

The strange things is I also tried with my laptop (which has a built in wifi and its work properly) and there work without any problem.

I tried fix this problem with this methods:
1., Install Realtek driver
2., WPA_GUI (it's return with authentication failed)
3., Windows driver/ndiswrapper
4., and so many ways....

Finally I gave up and now I use Windows, but I would like to go back to Linux Mint (13 LTS).

Here is some details about my PC (AMD 64 bit):

Router details:
- BTHome Hub 3.0 Type A.
- security WPA2

Both system is Linux Mint 14 XFCE with the latest updates, on PC I use 64-bit and on laptop 32-bit version.

Can anyone help to solve this problem?

Linux Mint is funded by ads and donations.
 

Re: TP-LINK TL-WN821N, RTL8192CU connection fail

Postby T_CH on Sun Oct 20, 2013 12:48 am

I have this adapter (TL-WN821N version 4 by the way) and it worked on mint cinnamon 15 - 32 bit , without using the console.
Download the appropriate windows driver from TP LINK's site and save it
Open software management and
a) install kernel sources (or linux kernel or whatever name it has ). I don't know if that's really necessary , but i do it with every linux distro I use , because many programs use them on installation.
b) install ALL the packages related to ndiswrapper (they are 5 I think - only 3 of them initially installed)
c) Run the ndiswrapper GUI (don't remember the exact name - it's something like "install wireless drivers")
d) Choose the windows driver for XP 32bit (net8192cu) . Drivers for 7/8 give error messages.
e) Reboot
Your adapter should me working now .
