Hi!
I downloaded official drivers (rt2800usb does not support rt3573), deselected (and blacklisted) all ralink stuff in the kernel, compiled and installed.
I get an ra0 interface (and not a wlan0).

With iwconfig:
Code:

ra0       Ralink STA 
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  invalid crypt:0  invalid misc:0


When I hit scan in wicd, I find no APs in range, and iwconfig says
Code:

ra0       Ralink STA  ESSID:""  Nickname:"RT2870STA"
          Mode:Auto  Frequency=2.412 GHz  Bit Rate:1 Mb/s   
          RTS thr:off   Fragment thr:off
          Encryption key:off
          Link Quality=10/100  Signal level:0 dBm  Noise level:0 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0


And led flashes as I was indeed connected. With an other kernel I had ESSID="11n-AP" but there is no such AP. And what is this Nickname field?

My dmesg has this stuff:
Code:

[  164.442669] RTMP_TimerListAdd: add timer obj ffffc90005aa56b0!

[  164.865521] 0x1300 = 00064300


My kernel is 3.6.1-pf, i have compiled CONFIG_IPW2200=m because i could not compile ralink driver without that (!!!) and CONFIG_IWLWIFI but nothing below CONFIG_RT2X00

Any idea?

Code:
ls /lib/firmware/rt2870.bin
if not present
Quote:
emerge linux-firmware


http://www.ralinktech.com/en/04_support/support.php?sn=501 driver came from here?

Quote:
ESSID="11n-AP"
name of somebody's router's network

Nickname:"RT2870STA" is leftover name for the NIC for which driver was developed several years ago.

Yes, I have installed firmware from sys-kernel/linux-firmware-20120924
Yes, driver was from this site.
No! This is not a real AP. There is no 11n-AP network in range, my other wifi card does not see it, and it just appears there always and immediately

Kernel config:
I cannot find Wireless extensions sysfs files
"Common routines for IEEE802.11 drivers" are mandatory compiled in (marked {M})


Code:

 # iwlist wlan0 scan                                                                                                                 
wlan0     Interface doesn't support scanning.
# iwlist ra0 scan                                                                                                               
ra0       No scan results
# iw dev ra0 scan                                                                                                                   
command failed: No such device (-19)
# iwconfig ra0                                                                                                                     
ra0       Ralink STA  ESSID:"11n-AP"  Nickname:"RT2870STA"

# ifconfig ra0

        TX packets 9524  bytes 968040 (945.3 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
# iwlist wlan1 scan | grep ESSID                                                                                                   
                    ESSID:"Auberge"
                    ESSID:"FreeWifi_secure"
                    ESSID:"dlink"
                    ESSID:"FreeWifi"
                    ESSID:"FreeWifi"

Note that my wlan1 does not detect any 11n-AP essid. Also note that I have not received a single byte from ra0. How did it connect?

Some output from dmesg:
Code:

[  139.761936] CfgSetCountryRegion():CountryRegion in eeprom was programmed
[  139.761955] CfgSetCountryRegion():CountryRegion in eeprom was programmed

Actually I did not configured any country.

Code:

RTMPSetPhyMode: channel is out of range, use first channel=1

Note missing of timing info. Why does it use ONLY channel 1? Actually the AP I wish to connect is at channel 13.

Code:

# iwlist wlan1 scan| grep '(Channel'                                                                                               
                    Frequency:2.467 GHz (Channel 12)
                    Frequency:2.467 GHz (Channel 12)
                    Frequency:2.472 GHz (Channel 13)
                    Frequency:2.467 GHz (Channel 12)

(wlan1 is my onboard intel iwlwifi card) - there are no channel 1 networks.

@galanom: if you run "make install" after compiling the driver from the Ralinktech site it installs an example config file in /etc/Wireless/RT2870STA/. This file contains the SSID you're seeing all the time. Try to modify this RT2870STA.dat to your likings or otherwise remove it completely to see what happens ...
