Install usb wifi tl-wn823n on Debian

Question

I need to install my TP Link USB dongle on Debian Wheezy. I already tried a bunch of different things and nothing seemed to work. Here is the result of some commands:

$ lsusb

Bus 002 Device 005: ID 0bda:8178 Realtek Semiconductor Corp. RTL8192CU 802.11n WLAN Adapter

$ lsmod | grep rtl

rtl8192cu              74897  0 
rtlwifi                81393  1 rtl8192cu
rtl8192c_common        52602  1 rtl8192cu
mac80211              192806  3 rtl8192c_common,rtlwifi,rtl8192cu
cfg80211              137243  2 mac80211,rtlwifi
usbcore               128741  5 ehci_hcd,usbhid,rtlwifi,rtl8192cu

I tried installing the driver from the official Realtek website and it worked but the dongle isn't working, no result with neither ip link nor ifconfig.

Any ideas ?

Solution

You have full support from official tp-link webpage, here is the source (to compile):

http://www.tp-link.com/res/down/soft/TL-WN823N(EU)_V2_160315_Linux.zip

http://www.tp-link.com/en/download/TL-WN823N.html#Driver

be careful with the hw version: you can choose v1 or v2.

Have you tried installing firmware from wiki.debian.org/Firmware (specifically, the rtl* debs)? You might have some luck re/installing Debian from a medium that bundles the non-free packages.

Are you sure you have the same USB device? The iwlwifi package provides firmware for Intel wi-fi adapters, not Realtek.
