wireless not working with rt2870

I’ll start with some information:

Opensuse 12.1
kernel 3.1.10-1.9-desktop

laptop Acer Aspire 5750G with Atheros wireless, some information found tells me this one is incompatible with linux,
so I bought an usb dongle from ASUS: usb N13 802.11/b/g/n because it’s mentionend as linux compatible.

BUT no connection either

what I found:

iwconfig l0 no wireless connection
eth0 no wireless connection

iwlist scan: l0 interface doesn’t support scanning
eth0 interface doesn’t support scanning

lspci | grep -i net: 03:00.0 network controller Broadcom Corp.BCM43227 802.11/b/g/n
but this answer is the same with our without the dongle; so it seems to come from the laptop

lsmod | grep acer*: cpufreq_userspec 12973 0

in dmesg found this: acer_wmi: no or unsupported WMI, interface unable to load
usb 2-1.1: Product 802.11n WLANN adapter
Manufacturer: Realtek
Serialnr: 00e04c000001

lsusb: bus 002 device 011: ID 0b05:17ab ASUSTEK Corp. Inc

rfkill list: no output of some information

hwinfo: (I limit to what I think is important)
54 USB 00:0:000 unclassified device
Model ASUSTEK 802.11n WLAN adapter
hotplay: usb
config status: cfg=no avail=yes need=no active=unknown

Furthermore these files are present:
/lib/modules/3.1.10-1.9-desktop/kernel/drivers/net/wireless/ath/ath9k/ath9k.ko (this probably points to the internal Atheros)
/lib/modules/3.1.10-1.9-desktop/kernel/drivers/net/wireless/rt2x00/rt2800usb.ko (this one for realtek)
/lib/firmware/rt2870.bin

The interface information shows only hardware connection, the wireless is greyed out

QUESTION: what do I miss? Do I have to do something I didn’t?? can somebody help me to get my wireless interface working???>:(

It is my humble task to point you to the use of CODE tags: http://forums.opensuse.org/english/information-new-users/advanced-how-faq-read-only/451526-posting-code-tags-guide.html

And we prefer that when you copy/paste computer text from a command, that you copy including the prompt and the command (and of course the output).

Try

su -
modprobe -r acer_wmi

To blacklist it permanently
edit: /etc/modprobe.d/blacklist.confadd this at the end
blacklist acer_wmi

wimmel: You likely need to install the kernel-firmware package. Check the output
of the dmesg command to see if it is mentioning a problem with firmware loading.

Caution: DO NOT post the entire output of dmesg. It is probably not needed, and
if you do, I will stop helping.

1.- blacklist acer_wmi sits in /etc/modprobe.d/blacklist.conf; most files in this map are starting with “50-…”: 50-blacklist.conf, is taht a problem?
2.- kernel-firmware is installed

any other idea?

The files in modprobe.d are processed in alphabetical order. Your name should
not be a problem.

Why does the subject say “rt2870”? Your device uses rtl8192cu as its driver. It
is a Realtek device, not one made by Ralink!

Does the iwconfig command now show wlan0? If not, then post the entire dmesg
output in a pastebin and post the link here.
