Can you explain how to understand what the 'iwconfig' command displays in Ubuntu-9.04?
- by Shawn
I'm having trouble making my wireless connection work, and I realized I don't really know how to use the tools I have, in this case, the iwconfig command in Ubuntu-9.04.
Here is what I get:
***iwconfig***
-
lo no wireless extensions.
eth0 no wireless extensions.
wmaster0 no wireless extensions.
wlan0 IEEE 802.11bgn ESSID:"Network"
Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
Tx-Power=20 dBm
Retry min limit:7 RTS thr:off Fragment thr=2352 B
Power Management:off
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
vboxnet0 no wireless extensions.
pan0 no wireless extensions.
"Network" is the name of my wireless network, btw.
But what does this all mean? How can this information help me aquire a working wireless connection?
When I try associating a key using
sudo iwconfig wlan0 key s:my_key
I get the following error message:
Error for wireless request "Set Encode" (8B2A) :
SET failed on device wlan0 ; Invalid argument.
I do have the right key though, so what's the problem?
