hi,

i want to use a LogiLink WL0085 Wireless N USB Adapter (http://www.logilink.com/showproduct/WL0085.htm) and lsusb gave that response back in terminal ...

Code:

Bus 002 Device 004: ID 0bda:8171 Realtek Semiconductor Corp. RTL8188SU 802.11n WLAN Adapter


i have already set my kernel with the needed staging driver and firmware up but in nm-applet under the cinnamon desktop it is seen as a !!! wired !!! (yes, not wireless!) network interface.

is this a known bug ?

anyway : any ideas how to fix this strange problem ? currently i am unable to use this device in any form except as a door blocker :-(

by the way : months ago (i think it was around end of spring 2012) it was already seen as a wireless network interface in nm-applet but always crashing the kernel when it was unplugged.

currently i am using these network related packages

Code:

net-wireless/wireless-tools-30_pre9  USE="-multicall"
net-wireless/wpa_supplicant-1.1  USE="ap dbus eap-sim gnutls p2p readline ssl wps -fasteap (-ps3) -qt4 (-selinux) -wimax"
net-misc/networkmanager-0.9.6.4  USE="avahi bluetooth connection-sharing dhcpcd gnutls introspection modemmanager ppp resolvconf vala -dhclient -doc -nss -systemd -wext -wimax"
sys-kernel/vanilla-sources-3.7.1:3.7.1  USE="symlink -build -deblob"
gnome-extra/nm-applet-0.9.6.4  USE="bluetooth gconf"


and of course the cinnamon-1.6.7-r1 desktop ui

which firmware?
Does
Code:
ifconfig -a
show the interface? If so, does
Code:
ifconfig
show the interface? If not, will
Code:
ifconfig wlan0 up
bring it up? Will it scan?
Code:
emerge wireless-tools
iwlist wlan0 scan
or
Code:
emerge iw
iw wlan0 scan

can you paste dmesg output?

Sometimes happens that wireless interfaces are named like ethN. If you look with iwconfig you'll see that lists eth1 as wireless interface. I think the culprit here is udev.

The performance issue might have to do with something else. Find online more about 'your device + linux' and see what others are saying. Anything in staging is likely not to be very stable, else wouldn't be there.

thanks guys for your help....

because of my /etc/udev/rules.d/70-persistent-net.rules file the wlan usb stick is recognized as interface wlan1. eth0 and wlan0 are internal network devices of my notebook.

Code:

# USB device 0x0bda:0x8171 (usb)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:13:33:xx:xx:xx", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan1"


i am using this udev implementation:

Code:

sys-fs/udev-197-r1  USE="acl gudev hwdb introspection keymap openrc -doc -kmod (-selinux) -static-libs"


this is the dmesg output but before this i had to shut down the networkmanager service:

Code:

r8712u: Staging version
r8712u: register rtl8712_netdev_ops to netdev_ops
[107478.335191] r8712u: USB_SPEED_HIGH with 4 endpoints
[107478.335699] r8712u: Boot from EFUSE: Autoload OK
[107478.878666] r8712u: CustomerID = 0x0000
[107478.878671] r8712u: MAC Address from efuse = 00:13:33:xx:xx:xx
[107478.878673] r8712u: Loading firmware from "rtlwifi/rtl8712u.bin"


i have blanked the last 24 bits of the mac address for security reasons.

iwconfig output after the "ifconfig wlan1 up" command:

Code:

wlan1     unassociated  Nickname:"rtl_wifi"
          Mode:Auto  Access Point: Not-Associated   Sensitivity:0/0 
          Retry:off   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0


EDIT:

the usb stick scans after the "iwlist wlan1 scan" command (with deactivated networkmanager service) with no results because i have currently no antenna attached and not available until tomorrow evening middle european time.

donahue, could you please name the new specific kernel module you speak of? i am currently using the r8712u kernel module.

i think you made a mistake by naming 2 exactly the same designation names of the staging drivers

I've seen a couple of places where both are listed as supporting your NIC

Code:

usb 2-1.2: new high-speed USB device number 5 using ehci_hcd


is the only response i got from the r8192u_usb kernel module in conjunction with my wireless usb nic.

this nic stays currently unusable with networkmanager and nm-applet.

best workaround up to now:
1. tell networkmanager to ignore the interface completely (ban the mac-address) of this wireless nic
2. use the r8712u kernel module with the rtl8712u.bin (size: 129.304 bytes) firmware
3. use the nic the classical way via console commands or gentoo configuration scripts at your discretion
4. cross the fingers :-) everything including encryption should be working as expected

hopefully networkmanager and nm-applet will learn that this is a real wireless usb nic WITH NO WIRELESS CABLE INCLUDED some day :-)
