Can't connect to wireless network with a Sabrent A111N USB Dongle

I've been trying to connect to this network for quite some time. I can't directly connect to the router with a Wire, but can access the Router with other wireless devices without any issues.

I had previously tried several other Wifi nic's but none of them would load properly.

Today, i went and bought a new (supported) Sabrent A111N USB Dongle, which said explicitly that it works with Linux 2.4 +.

I popped the Dongle in, and low-and-behold it immediately said that there were Available Wireless Connections. I selected my connection and tried to connect, but it just loops constantly while saying Wireless Disconnected then attempts to connect again over and over.

ifconfig and iwconfig both show my device in a ready and working state. However, iwlist wlan0 scan says that there are no results found. I don't get it...

At one point, I could see the CPU in the DHCP client list under the router, but it doesn't fully make the connection (something about a timeout?).

Any help would be appreciated.

While RTL8188CUS is indeed supported, and should work out of the box, and yet, there are reports around the WWW that it doesn't. The device 'sees' the networks around, but won't connect to them. Here is a bug report.

That said, you can get it to work by downloading and installing the driver from Realtek. The device uses the rtl8192cu module by default, which can be varified by running lsmod | grep 8192 in a terminal.

Download RTL8192CU for Linux from Realtek.

Right click the downloaded file, select Extract Here.

Before installing, you need to blacklist the broken module, so run the following and reboot.

echo 'rtl8192cu' | sudo tee -a /etc/modprobe.d/blacklist.conf

Now open a terminal window and change to the driver folder

cd RTL8188C_8192C_USB_linux_v3.4.4_4749.20120806

Run sudo bash ./install.sh

Wireless should start working now. You'll need to reinstall the driver after every kernel update.
