Wireless Problems: With WPA Supplicant

Hello Everyone,

I don't have much experience setting up my wireless manually, and I thought it would be a good exercise to try. Once I have successfully done this, I'll proceed to using a client. From that line of reasoning, Lo and behold, I am now stuck here.

Below is the output of iwconfig without connecting my ethernet and with connecting my ethernet, respectively. I have also removed my essid.

Code:

---

# iwconfig
lo        no wireless extensions.

wlan0    IEEE 802.11abg  ESSID:"**" 
          Mode:Managed  Frequency:2.462 GHz  Access Point: Not-Associated 
          Tx-Power=14 dBm 
          Retry  long limit:7  RTS thr:off  Fragment thr:off
          Encryption key:off
          Power Management:off
         
eth0      no wireless extensions.

# iwconfig
lo        no wireless extensions.

wlan0    IEEE 802.11abg  ESSID:"**" 
          Mode:Managed  Frequency:5.745 GHz  Access Point: 68:7F:74:C6:0E:AE 
          Bit Rate=18 Mb/s  Tx-Power=14 dBm 
          Retry  long limit:7  RTS thr:off  Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=70/70  Signal level=-36 dBm 
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0  Missed beacon:0

eth0      no wireless extensions.

Neither case allows me to access the internet wirelessly.

To explain further:
I've been reading documentation about using 'wpa_supplicant' to set up a wireless connection using WPA2, and have proceeded to configure wpa_supplicant.conf file manually.

I believe my problem occurs when I use the command
# wpa_supplicant -B -Dnl80211 -i wlan0 -c /etc/wpa_supplicant.conf

As documentation has informed me that I am to receive output that reads "Authorized", yet I do not receive any such output. I have done research online on Google, and various sources of documentation found online.

Perhaps my knowledge is limited, or perhaps a particular key piece of information among the documentation I've read has slipped my eye. Regardless, I am now in this situation, and I would love to find the solution to my problem.

If you can link me to documentation or any other resource that can help me, I would appreciate it.

replace -B option with -d to run wpa_supplicant in the foreground. The output might give you some clue

It is possible that the default gateway is not set. Look at the output of this command:

Code:

---

route -n

---

If the gateway is not correct, then that could be the problem. See this for more info:
