Hello all. I just installed Kali on my hard drive using a bootable usb stick with the 64 bit iso. I can connect to a wireless router using the graphical interface with no problem. However, when trying to connect from the command line using: iwconfig wlan0 essid <essid of router> key<hex key> , then: dhclient wlan0, the cursor hangs. Eventually the ping statistics show 0 packets received and 100% loss. I've tried setting static ips and I still can't connect from the command line. Once again, using the graphical interface allows me to connect fine. I suspect I need to configure a file. Any advice? Thanks.
