rtl8187 problems

Hi,

I have been trying really hard to get my wireless working but so far no success. I have a Asus M2N32-SLI Deluxe motherboard which has a built in usb wireless system. This is based on the rtl8187 chip. rtl8187 is included in the lastest kernel and I can easily modprobe it. So I added it to my modules section in my rc.conf however it doesn't seem to load. When I run:

dmesg | grep rtl8187

I get:

rtl8187: Cannot register device
rtl8187: probe of 2-9:1.0 failed with error -2
usbcore: registered new interface driver rtl8187

However when I remove the module using modprobe -r and then reload it I get this:

rtl8187: Cannot register device
rtl8187: probe of 2-9:1.0 failed with error -2
usbcore: registered new interface driver rtl8187
usbcore: deregistering interface driver rtl8187
phy0: hwaddr 00:15:af:29:2e:51, rtl8187 V1 + rtl8225z2
usbcore: registered new interface driver rtl8187

After this it starts working and I actually managed to get a connection.

I tried to search around but I can't find any info. Does anybody have any idea what all this means?

Re: rtl8187 problems

Hi,

I finally managed to get my driver to work. After experimenting for a while I discovered that I could easily connect to my wireless internet when it is not secured (ie. no WEP or WPA). The connection is strong and I have no problems with it.

However when I turn on WEP or WPA it simply refuses to connect. NETCFG complains that it can't associate to the network. Not sure what this means.

Can somebody explain how I can go about diagnosing the problem? Which logs should I look up to see specific details about whats going on?

Re: rtl8187 problems

I never managed to solve this problem but I've come back again and tried. I've discovered a couple of new things.

Firstly whilst rtl8187 is loaded as a module on startup for some reason it doesn work. I have to

rmmod rtl8187

and then reload it. After that I get my "wlan0" interface.

I then use netcfg2 to connect to my network and that works fine. I get the following:

[timo@myhost ~]$ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

eth1      no wireless extensions.

wmaster0  no wireless extensions.

wlan0     IEEE 802.11  ESSID:"Malta"
          Mode:Managed  Frequency:2.412 GHz  Access Point: 00:90:4B:7A:D1:9B
          Bit Rate=9 Mb/s   Tx-Power=27 dBm
          Retry min limit:7   RTS thr:off   Fragment thr=2352 B
          Link Quality=59/64  Signal level=57/65
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

As you can see I am connected to my wireless network. However nothing works. I can't connect to the internet or anything. Its a bit wierd.

Any ideas what could be causing these issues. Just for info here is my netcfg profile:

ONNECTION="wireless"
INTERFACE=wlan0
SCAN="yes"
SECURITY="wpa"
ESSID="Malta"
KEY="***************"
IP="dhcp"
TIMEOUT=20

Would a connection be established if my key is wrong.
