News on Buffalo's WLI-UC-GNHP, an WiFi adaptor for USB
WLI-UC-GNHPのユーザの多くは日本人かも知れないが、英語で書いておく. 簡単なので許されたし. (Allow me to write in English although most users may be Japanese.)

Here it's explained how to use Buffalo's WiFi adaptor WLI-UC-GNHP (vendor's pages: English, Japanese) with recent Linux.

Summary: Use kernel >= 3.2. It's known to work with 3.0.4 with one-liner. Probably compat-wireless-3.0 is ok.

Kernel >= 3.2
In-kernel driver works, by pulling in the firmware. The kernel config:

The necessary firmware  is provided by kernel.org:

Kernel 3.0, 3.1
Kernel 3.0 and 3.1 need some more steps. First, the kernel config:

One more step is necessary.'' Inform the driver on your WiFi adapter IDs. This can be done in either of these two ways:

1. By using sysfs "new_id" file: modprobe rt2800usb echo "411 158" > /sys/bus/usb/drivers/rt2800usb/new_id

2. By patching the kernel source: --- linux-3.0.4/drivers/net/wireless/rt2x00/rt2800usb.c.orig 2011-10-11 21:04:16.893188320 +0900 +++ linux-3.0.4/drivers/net/wireless/rt2x00/rt2800usb.c 2011-10-11 21:04:16.893188320 +0900 @@ -1039,6 +1039,7 @@ 	{ USB_DEVICE(0x0411, 0x012e) }, { USB_DEVICE(0x0411, 0x0148) }, { USB_DEVICE(0x0411, 0x0150) }, +	{ USB_DEVICE(0x0411, 0x0158) }, { USB_DEVICE(0x0411, 0x015d) }, /* Corega */ { USB_DEVICE(0x07aa, 0x0041) },

When it's ready it'll become available as "wlan0". (Run )

Problems
It seems better to turn off the WiFi connection before unplugging the dongle. Otherwise, sometimes kernel oops, and kernel may freeze.

Older kernels
In general, there're 2-3 choices: use the "staging" driver in the kernel, the module provided by Ralink Corp, or if available, the kernel's official driver. The first two methods are explained in Ralink RT2870. Anyway, apply the patch similar to the above one.

But with kernel 2.6.39, almost all doesn't work. The staging driver is problematic, and the Ralink's code can't be compiled. (You can avoid an obstalce by artificially inserting  into the kernel configuration code, but a tougher one will block you.)

The official code works by patching, but sysfs "new_id" method makes the kernel freeze.

Unless they are being specifically referenced as part of instructions, links to external sites, including wiki.gentoo.org should go at the end of the article under a heading such as "See Also", "Related Articles" or "Links"

 * Hi, thanks for your message.
 * You know, something has to be done. It's for 99% Gentoo users. For example, Template:Official can be put at the top of the page, so the rule "external links at the bottom" is not a cure-all, though wgo pages are not official docs. I've added "see also" also to the top of w.g.o counterpart pages. (I know wgo is independent of this wiki.)
 * The seperation of two wikis is very unfortunate, and will be another failure in Gentoo community without some kind of improvement. At least there should be a conspicuous markup by a new template, both for readers and to bust "don't care the counterpart" contributors. (I know the license issue.)
 * Last but not least, let me take this opportunity to express my great gratefulness for your dedication to Gentoo Wiki. And TIA for its future. - Teika 12:24, 26 November 2011 (GMT)
