Wlan0 :file not found
hello guys
this is me : Linux home 2.6.18-53.el5 #1 SMP Mon Nov 12 02:22:48 EST 2007 i686 i686 i386 GNU/Linux i have wireless card on this laptop and it is a broadcom. my gnome network manager had only my eth0 , so i pushed the "New" botton i found a wlan0 interface ready to add with this driver b43 . ok now i have an interface Wlan0 in my gnome network manager, here comes the problem when i try to activate this adapter i get this error : Determining IP information for wlan0...SIOCSIFFLAGS: No such file or directory SIOCSIFFLAGS: No such file or directory and my "#ifconfig" have an output too : wlan0 Link encap:Ethernet HWaddr 00:19:7D:32:DA:1C 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 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) what should be done guys ??? thanks a lot in advance |
If it shows up in ifconfig, you are almost there. Do all commands below as root.
First: ifconfig wlan0 up ifconfig verify that wlan0 is now UP. Next: iwconfig wlan0 essid <name_of_access_point> key <yourkey> <yourkey> becomes s:<yourkey> if yourkey is ascii. iwconfig to verify that it associated dhcpcd wlan0 ( or dhclient ) |
these are the results :
[root@jumaro /]# /sbin/ifconfig wlan0 up SIOCSIFFLAGS: No such file or directory [root@jumaro /]# /sbin/iwconfig wlan0 essid home key 1234512345 [root@jumaro /]# /sbin/iwconfig lo no wireless extensions. eth0 no wireless extensions. wmaster0 no wireless extensions. wlan0 IEEE 802.11 ESSID:"home" Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated Tx-Power=0 dBm Retry min limit:7 RTS thr:off Fragment thr=2352 B Encryption key:1234-5123-45 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 pan0 no wireless extensions. virbr0 no wireless extensions. |
OK--ifconfig wlan0 up did not work---I'm stuck on why it shows up in ifconfig. Did you actually do "ifconfig -a" to make it appear? (On my machine, ifconfig shows nothing if the particular interface is down.
All I can think of for the moment is to cycle thru these 3: ifconfig wlan0 down ifconfig wlan0 up ifconfig |

If you run the /sbin/iwconfig wlan0 essid <youressid> key <s:yourkey> again, run /sbin/iwconfig wlan0 afterwards to only display info on the wireless adapter. Good luck, Geoff. |
the gnome network manager is used for the wireless adapter setting
i tried these : /sbin/iwconfig wlan0 essid <youressid> key <s:yourkey> again, run /sbin/iwconfig wlan0 and this is what i got : [root@jumaro /]# /sbin/iwconfig wlan0 essid mb-pc key s:12341234 [root@jumaro /]# /sbin/iwconfig wlan0 wlan0 IEEE 802.11 ESSID:"mb-pc" Mode:Managed Frequency:2.462 GHz Access Point: Not-Associated Tx-Power=27 dBm Retry min limit:7 RTS thr:off Fragment thr=2352 B Encryption key:3132-3334-3132-3334 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 |

after insertion of the firmware i dont get the "file not found" .
and i rebooted and put the IP manually and the wlan0 got activated seccessfuly . but the /sbin/iwconfig still gives me that its not associated . and i cannot ping the gateway also . |
is there any software that could manage my wireless networks more clear than the gnome network utility ?
|
everything is fine now :)
and several reboots and some self discovering i noticed that the networkmanager doesnt support the kind of WAP key that my access point has so i changed to something that matches it and thats it ... GOOD BYE to WINDOWS im realy happy this fedora9 ROCKS , love it thanks alot guys |
We like happy endings....and we REALLY like people like you who don't wait for out feeble efforts but rather charge ahead a make it work. Soon, you will be helping US....;)
To address an earlier question: I don't like ANY of the GUI wireless managers. I use wireless-tools (iwconfig, iwlist, etc.) for everything. Eventually, I will write some simple scripts to save me keystrokes. |
