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 [B]to blacklist the rt2800usb rt2x00usb and rt2x00lib modules[/B] 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 *************"
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
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.
