Works on recent Linux kernels (3 and 4). For Debian/Ubuntu. I want to run rtl8192cu driver for concurrent mode. Compile and install rtl8192cu driver. Can someone tell me where I can download compiled driver and where I need to put. Install rtl8814AU driver on ubuntu 16.04. Rtl8192cu Linux Driver RTL8192CU, driver blob download. Installing WIFI drivers on Linux Ubuntu - Easy.
This is a repackaging of Realtek's own 8192CU USB WiFi driver for Ubuntu 13.10 and later.
This driver is not explicitly maintained.
rtl8xxxu driver initially introduced in kernel 4.4 works mostly well these days, and you should give it a try before trying this repository.
rtl8xxxu gives you problems, try troubleshooting it first. Known things to look for are:
Make sure to blacklist the older
rtl8192cudriver, which some distros seem to load by default otherwise.
Some devices require that power management be disabled in NetworkManager. Follow the instructions further down to disable power management in NetworkManager. Typical symptoms would be that the device works fine for a moment, and then becomes very slow or outright drops the connection.
If your device is not detected, make sure that your kernel enables CONFIG_RTL8XXXU_UNTESTED
Be sure to set the options for DMA aggregation and dual-band 2.4 GHz:
In some cases, though, this driver has been known to work fine where
rtl8xxxu doesn't. If
rtl8xxxu doesn't work for you even after the troubleshooting steps listed above, follow the instructions below to install this one instead.
These devices are known to work with this driver:
- ASUSTek USB-N13 rev. B1 (0b05:17ab)
- Belkin N300 (050d:2103)
- D-Link DWA-121 802.11n Wireless N 150 Pico Adapter [RTL8188CUS]
- Edimax EW-7811Un (7392:7811)
- Kootek KT-RPWF (0bda:8176)
- OurLink 150M 802.11n (0bda:8176)
- Plugable USB 2.0 Wireless N 802.11n (0bda:8176)
- TP-Link TL-WN725N (0bda:8176)
- TP-Link TL-WN821Nv4 (0bda:8178)
- TP-Link TL-WN822N (0bda:8178)
- TP-Link TL-WN823N (only models that use the rtl8192cu chip)
- TRENDnet TEW-648UBM N150
These devices are known not to be supported:
- Alfa AWUS036NHR
- TP-Link WN8200ND
As a rule of thumb, this driver generally works with devices that use the RTL8192CU chipset, and some devices that use the RTL8188CUS, RTL8188CE-VAU and RTL8188RU chipsets too, though it's more hit and miss.
Devices that use dual antennas are known not to work well. This appears to be an issue in the upstream Realtek driver.
Ensure you have the necessary prerequisites installed:
Clone this repository:
Set it up as a DKMS module:
Build and install it:
Refresh the module list:
Ensure the native (and broken) kernel driver is blacklisted:
And reboot. You're done.
The instructions above should work in every Debian-based distribution. So long as you can install the prerequisites on your own, everything after the line that contains
apt-get should work in other distributions as well.
On Gentoo, you can disregard the instructions above and just install the following ebuild: https://gitweb.gentoo.org/dev/maksbotan.git/tree/sys-kernel/rtl8192cu-fixes/rtl8192cu-fixes-9999.ebuild
There is a known issue with power management on some hardware. If your WiFi connection drops after a few minutes, install the following module setting file to disable power management in your WiFi interface:
And then reboot.
Sometimes Network Manager also sets a device in a power-saving mode where it doesn't use enough power to connect. You can fix it by editing
/etc/NetworkManager/conf.d/default-wifi-powersave-on.conf and setting
wifi.powersave to 2. And then reboot.
As it currently stands, the driver doesn't populate /proc with informational data from the driver. The API for /proc has changed in recent kernels, and the driver has not been ported to the new API.

This repository was initially based on Timothy Phillips's work as published here: https://code.google.com/p/realtek-8188cus-wireless-drivers-3444749-ubuntu-1304/, though no longer.
Thanks go to Saqib Razaq (@s-razaq) for the power management workaround.
Thanks to @CGarces for the Travis configuration.
