fedora wireless question

itsbrad212 · 01-03-2010, 06:18 PM

I have installed fedora 12 a few weeks ago, and the wireless worked out of the box. Now, when I go to the network icon in the top right and click on it, it comes up with "Network Disabled". I don't know why it would just do that. How can I enable it?

output of lspci:

I also tried:

Code:

chkconfig network on

but that didn't work. Please HELP!

I see you have two adaptors, one ehternet and one wireless. Open a konsole, and run the command 'ifconfig' ( without the quotes ). That will list all interfaces on the system.

In the left column, you will see some names. eth0 is probably your wired ethernet card, ( the Realtek hardware ).

There will be another name, possibly ath0, that is just a guess. What ever that name is, in the konsole run the command 'ifconfig nameyoufind up' ( without quotes ). Cut and paste the results here.

Also run the command 'iwconfig nameoftheadapteryoufind' and post the results.

If things are not working after you run the commands, please also tell us about the wireless access point ( your router)... make model etc. Can you connect to it with another system and look at the status of things from there?

Well, I know it is wlan0. I'll go and try that. I am posting from my ubuntu live cd which works just fine.

iwconfig wlan0:

Code:

wlan0     IEEE 802.11bg  ESSID:"2WIRE167"  
          Mode:Managed  Frequency:2.422 GHz  Access Point: 00:1B:5B:11:75:D1   
          Bit Rate=18 Mb/s   Tx-Power=20 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=31/70  Signal level=-79 dBm  Noise level=-98 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

I'll be back with the output of ifconfig wlan0 up

Ok, I just ran ifconfig wlan0 up, and there was no output. I went up to the network icon and it still said disabled.

There has to be some output, if you have to correct name of the adapter, whether it is up or down. Do an 'ifconfig' all by itself. There may be several names listed.

Please also post the results of this command, and about your access point.

I posted it before

EDIT: Oops, I did iwconfig.

Here is ifconfig wlan0:

Code:

This is interesting. You get an IP address, so you have talked to the access point, and iwconfig shows the name of the access point.

Have there been any changes to the access point?

If you open a browser, and type http://192.168.1.1 can you connect to the access point? BTW, I'm guessing the IP address of the access point ends in a .1, change that to match if it does not.
