Anybody have information on how to build a proper driver for this WiFi receiver? It claims to work on Linux, but performance is not good and the unit does not have good directions. It is not listed at all on http://linux-wless.passys.nl/query_h...php?hostif=USB.

Thanks!

try ndiswrapper & windows driver. I never learned the detail myself, but it's out there.

Sorry, I am looking for a genuine Linux solution in this case.

OK. Did you put it in and run lsusb -vvn(presuming usb)
The n gives you manufacturer id and device number instead of descriptions. From what you say, it could be a well known chip in an unfamiliar box.

This is what I get:
lpm@lpm-Ubantu9102:~$ lsusb -vvn
lsusb: invalid option -- 'n'
Usage: lsusb [options]...
List USB devices
-v, --verbose
Increase verbosity (show descriptors)
-s [[bus]:][devnum]
Show only devices with specified device and/or
bus numbers (in decimal)
-d vendor:[product]
Show only devices with the specified vendor and
product ID numbers (in hexadecimal)
-D device
Selects which device lsusb will examine
-t
Dump the physical USB device hierarchy as a tree
-V, --version
Show version of program

From other sources the chipset appears to be Reaktek RTL8187.

I downloaded some things from Realtek's web site, but the directions were quite poor.
There also appeared to be four different chip sets with similar numbers, none with exactly these numbers.

Hmmph! lsusb doesn't take -n?

You can get the same info by grepping for rtl 8187 in the file /usr/share/usb.ids - occasionally hidden in other places by distros.

Okay, here is the result of the grep:
010c Realtek RTL8187 Wireless 802.11g 54Mbps Network Adapter
4260 WG111(v3) 54 Mbps Wireless [RealTek RTL8187B]
6a00 WG111(v2) 54 Mbps Wireless [RealTek RTL8187L]
8187 RTL8187 Wireless Adapter
8189 RTL8187B Wireless 802.11g 54Mbps Network Adapter
8197 RTL8187B Wireless Adapter
8198 RTL8187B Wireless Adapter

It looks to me like RTL8187B, but could it be RTL8187L instead?

lsusb -vv? That should tell you what the chip is.
lshal |grep -iC12 Network
or maybe 802\.11 for a wireless device. Search for threads with that device - plenty of Realtek chips about, and check on
