I'm attempting to use a
RaLink RT2760 Wireless 802.11n 1T/2R Cardbus. This card auto-configures beautifully under Ubuntu 11.04, but I have a need for 10.04 LTS server, so I'm re-imaging.
I configure ethernet cards in 10.04 on a regular basis for work, but have never tried wifi. Here's hoping that this is a simple case of a forgotten step.
$ iwconfig wlan0 RT2860 Wireless ESSID:"" Nickname:"RT2860STA" Mode:Auto Frequency=2.412 GHz Access Point: Not-Associated Bit Rate: 1 Mb/s RTS thr:off Fragment thr:off Link Quality=10/100 Signal level:0 dBm Noise level:-87 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc: 0 Missed beacon:0
I'm assuming by the above that the driver is doing its job correctly.
auto wlan0 iface wlan0 inet static address 192.168.2.199 gateway 192.168.2.1 dns-nameservers 192.168.2.1 netmask 255.255.255.0 wpa-driver wext wpa-ssid MY_SSID wpa-ap-scan 1 wpa-proto RSN wpa-pairwise CCMP wpa-group CCMP wpa-key-mgmt WPA-PSK psk hashed_password
Then I try to start it
$ sudo ifup wlan0 wpa_supplicant: /sbin/wpa_supplicant daemon failed to start run-parts: /etc/network/if-pre-up.d/wpasupplicant exited with return code 1 ssh stop/waiting ssh start/running, process PID
Any assistance much appreciated.
$ iwlist scan wlan0 No scan results
This seems bad. The network is most definitely up and discoverable.
It looks like the boot cd installed me the rt2860 driver. According to a really old reference post on the forums, the RTxxx drivers may not be compatible with WPA2. I say may because I cannot find any up to date information on this issue. My network is secured WPA2-PSK AES.
