Sorry in advance for the long post...
Despite following directions from the relevant wiki pages, http://wiki.archlinux.org/index.php/Rtl8187_wireless and http://wiki.archlinux.org/index.php/Wireless, I was unable to get the realtek 8187b interface working properly. The module would install correctly and dmesg|grep rtl8187 would respond with the usbcore message, but wmaster0 and wlan0 would not show up.
I then checked the rtl-wiki https://sourceforge.net/forum/forum.php … _id=652149 and found someone else having a similar problem in fedora. After trying their solution, the interfaces at least show up. I can't test the wireless since I'm at work, but I have high hopes
Here are the steps I took:
1) Made sure the module was loaded properly
dmesg|grep rtl8187
Output:
usbcore: registered new interface driver rtl8187
2) Then
lsusb -vv | less
Page through the output until you see a Configuration Descriptor like this:
>snip<
Bus 006 Device 002: ID 0bda:8189 Realtek Semiconductor Corp.
Device Descriptor:
bLength 18
bDescriptorType 1
bcdUSB 2.00
bDeviceClass 0 (Defined at Interface level)
bDeviceSubClass 0
bDeviceProtocol 0
bMaxPacketSize0 64
idVendor 0x0bda Realtek Semiconductor Corp.
idProduct 0x8189
bcdDevice 2.00
iManufacturer 1 Manufacturer_Realtek
iProduct 2
iSerial 3 00e04c000001
bNumConfigurations 1
Configuration Descriptor:
bLength 9
bDescriptorType 2
wTotalLength 81
bNumInterfaces 1
bConfigurationValue 1
iConfiguration 4 Wireless Network Card
bmAttributes 0x80
(Bus Powered)
MaxPower 500mA>snip<
(this goes on for a while)
The lines you need are the following:
idVendor 0x0bda Realtek Semiconductor Corp.
idProduct 0x8189
3) Given the idVendor and the idProduct, you can now (hopefully) enable the device like so:
echo -n "0x0bda 0x8189" > /sys/bus/usb/drivers/rtl8187/new_id
4) You should then see a message similar to this one at the end of your dmesg
dmesg | grep phy0
Output:
phy0: hwaddr 00:16:44:7c:c8:47, rtl8187 V0 + rtl8225
phy0: RF Calibration Failed! 0
(i'm not sure what the RF calibration message means)
5) iwconfig should now return something like this:
lo no wireless extensions.
eth0 no wireless extensions.
wmaster0 no wireless extensions.
wlan0 IEEE 802.11g ESSID:""
Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated

Encryption key:off
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0

I've been banging my head into this for a couple of hours now, so I hope this helps someone else.

Use kernel 2.6.24, for many wireless improvements.

Im having the same problem with this rtl8187 in my Gateway Laptop, gonna try your solution later, and yes, I tried exact same thing of wiki and nothing! thx for posting btw dude

I've tested your method and it worked, now at least I can get the wlan0 up, but I tried scanning, and it didnt found nothing, when I tried with my psp I've got some results, im gonna test in my work now, but I dont think the card is working properly
another thing Ive noticed, is that in my ifconfig result my eth0 says in the end, "Interrupt: 16 Base address:0xc000"
shouldnt wlan0 says something about Base address like that?
