QUESTION: What is the best driver for a rtl8188 USB WiFi adapter?

I was messing with eBay and found what I thought was a good deal 3 USB WiFi with removable antennas for a cheep price. They were advertised as raspberry pi compatible rt5370 type devices. It is appears that I actually have three rtl8188 based devices.

The only solid info I have on them is that lsusb yields
Code:
Bus 002 Device 004: ID 0bda:f179 Realtek Semiconductor Corp.

So after some googling around, it appears that I have something based on the rtl8188 chip. Bad news: it's the driver is not mainline kernel. Good news: There is a driver for in in GetHub. bad news: There is not not a single driver for it but dozens of drivers. Just searching GetHub for "RTL8188" yielded 117 results (don't know if all are actual drivers).

I am wondering if anyone here has gotten a RTL8188 chip to work and what to you think of them. I have experience compiling modules that are outside of the main line kernel. But I do know that things have changed since the ol' 2.4.X kernel days.

My main computer runs Gentoo with the LTS 4.9 branch of kernel and I intend to stick with that branch for a while. I am also interested in using the WiFi adapters with my Raspberry Pi. Although I'm not sure about trying to compile a whole Raspberry Pi kernel.

I am wondering if it is worth the effort to get a proper driver, or should I spin the wheel and try again with a different eBay store.

TheLexx,

Look under staging in your kernel. I don't have 4.9 to check but there is a R8188EU driver in later kernels.

Code:
$ git grep R8188EU -- '*Kconfig*'                         
drivers/staging/rtl8188eu/Kconfig:2:config R8188EU
$ git blame drivers/staging/rtl8188eu/Kconfig
6ddfa35a4a98d (Larry Finger       2013-08-21 22:34:13 -0500  2) config R8188EU
$ git describe 6ddfa35a4a98d
v3.11-rc5-793-g6ddfa35a4a98
From this, we see that the Kconfig option was added after v3.11-rc5. I cannot comment on the minimum kernel version where the driver would be of acceptable quality.
