Wireless connection in Arch



I installed Arch Linux yesterday.

Well, I've a Conceptronic c150ru, which lsusb is:

Bus 001 Device 003: ID 148f:3070 Ralink Technology, Corp. RT2870 Wireless Adapter

so I followed this instructions:

The 2.6.31 kernel caused the rt2870 driver to conflict with other wireless modules. The fix in this thread says that you need to blacklist the rt2800usb rt2x00usb and rt2x00lib modules by modifying the MODULES array in /etc/rc.conf


Then, I've modified the /etc/rc.conf file in this way:


So, I've written this.

wlan_wlan0="wlan0 essid WLAN_92 key *************"
INTERFACES=(eth0 wlan0)

Where the asterisks are letters and numbers.

But wifi doesn't work. When I write iwconfig, this appears:

wlan0 Ralink STA ESSID:"WLAN_92" Nickname:"RT2870STA"
Mode:Managed Frequency=2.422 GHz Access Point: 00:1A:2B:05:69:89
Bit Rate=54 Mb/s
RTS thr:off Fragment thr:off
Encryption key:off
Link Quality=100/100 Signal level:-61 dBm Noise level:-83 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

And at the start it says:

Starting network [BUSY]
...IFFLAGS: No such file or directory
...for wireless request "Set Encode" (0B2A) :
Set failed on device wlan0 ; Invalid argument.
Could not associate wlan0 - try increasing WIRELESS_TIMEOUT and check is WEP or has no security

Well, I think that it's all. If I haven't wifi, I can neither install anything nor update the system.
