Are you inseparably wedded to this Realtek device you purchased? If yes, then ignore this post. If no, read on...
When I was looking for a new USB wireless card for my desktop, I spent time on the this site:
http://wireless.kernel.org/en/users/Drivers
I had at one time purchased a device from D-Link or Cisco that was based on the Realtek drivers, and I had no end to my headaches in getting it to work well on Gentoo box. Then I found out somewhere, can't recall if it was here or on one of vendor site's (i.e Newegg) review areas, that the devices built around the Atheros chipsets have very good support in Linux. Based on some positive online reviews, I chose this USB card from TP-Link; it uses the ath9k_htc driver IIRC. My experience has been very good. No packet loss or difficulty staying associated with my wireless router like the cards using the Realtek chipset seemed to suffer from. I also like the form factor and dual antennae so I can adjust/position this device to optimize signal.
My advice to you would be rather than trying to battle Realtek's issues, ditch the card and go with something leveraging Atheros instead. |

I would say the same about Broadcom, namely b43.

By the time I had a Broadcom wireless card, a couple of years ago, the b43 driver was not working at the beginning. I had to use the broadcom-sta wl module from Broadcom itself to make my wireless card work. Before I change the laptop and after several updates the b43 was working. Time have pass. I hope Linux have ameliorate the Broadcom wireless cards support.
Recently I went to a Linux meetup. Someone there who have a Broadcom wireless card told me that all other Linux distributions than Fedora made his laptop freeze when he try use it. That could probably be discuss, but I would not recommand a Broadcom wireless card to anyone that can have an Atheros or the ones based on Ralink technologie.
Presently, I have two wireless card that work well on Linux. They are both on PCIe bus.
Atheros AR9485 Wireless Network Adapter [168c:0032] (ath9k)
Ralink corp. RT5390 [1814:539f] (rt2800pci)

I have a edimax 7811un also, and was able to get the Realtek driver to compile with 3.12.5 and 3.12.7 kernels using some info I found from Arch
https://aur.archlinux.org/packages/dkms-8192cu/?setlang=nl&comments=all
It seems that it would solve the problems with the in kernel drivers.
However when I insert the device and try to enable it I get this

I have the USB 8192cu wifi dongle as well. I find the kernel driver just drops connections and is completely unstable. The site previously mentioned by someone (at https://github.com/dz0ny/rt8192cu) has some info for Ubuntu but not for Gentoo. I follow the instructions to se git to clone the driver directory. Then when I sudo make dkms I get this error:

Can anyone please help to get this 9192cu driver working?? |
