I've recently started working with Ubuntu Server 10.04, but I'm having a problem while connecting to WEP-encrypted Wifi.
I've tried the following:
sudo ifconfig wlan0 down sudo dhclient -r wlan0 sudo ifconfig wlan0 up sudo iwconfig wlan0 essid "<essid>" sudo iwconfig wlan0 key <hex key>
Then, I tried to connect to the Wifi by running
sudo dhclient wlan0, however, I keep getting the same error- No DHCPOFFERS received.
Am I doing this the right way, or is there something I'm forgetting?
sudo ifconfig yields:
wlan0 Link encap: Ethernet HWAaddr 00:1f:1f:3b:3c:3e UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 X bytes:0 (0.0B) TX Bytes:0 (0.0B)
sudo iwconfig yields:
wlan0 IEEE 802.11bg ESSID:"GlobalNetwork" Mode:Managed Access Point: Not-Associated Tx-Power:8 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:my-hex-key Power Management:off
I'm trying to connect with a Ralink RT2561 that shows up with
lshw -C network.
Any help you can give me is much appreciated, what am I doing wrong?
