WICD not detecting my wireless network

[jimjesus]

So I was having troubles getting wireless and wired to work on ubuntu so I installed the WICD manager. Now I can get wired to work just fine but for some reason, its not detecting my wireless network. All the other laptops in my house that use windows can see the network just fine but wicd just isn't seeing it, it says "no wireless networks found". Perhaps its not detecting my wireless card. How do I get it to see my wireless network?

Go to Preferences and make sure that the wireless interface option is set to your wireless interface. The command "iwconfig" will tell you which it is, it should be like wlan0, or eth1, or ath0, or something similar.

[jimjesus]

Well iwconfig outputs

lo        no wireless extensions.

eth0      no wireless extensions.

wmaster0  no wireless extensions.

wlan0     IEEE 802.11g  ESSID:"1337"  
          Mode:Managed  Channel:0  Access Point: Not-Associated   
          Tx-Power=0 dBm   
          Retry min limit:7   RTS thr:off   Fragment thr=2346 B   
          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

And my wicd has the wireless interface set to wlan0. It still isn't detecting my wireless network though. could it have anything to do with wireless supplicant driver?

[Whiffle]

Try doing:

sudo iwlist wlan0 scan


Try it several times in fact, I know my wireless tends to be a little slow on the startup. I generally have to click the "refresh" button in WICD a few times to get a list.

Did you ever get your wifi to work pre-Wicd?

The following info would be useful (NB. capital C):

lshw -C network

[jimjesus]

Well I tried sudo iwlist wlan0 scan and it said:

wlan0     Interface doesn't support scanning : Network is down

And no I never got it to work before wicd, actually my wired wouldn't even work pre-wicd. I tried that command and it said I should run it as a super user but it gave me an output anyway, and in that there was something interesting.

*-network DISABLED
       description: Wireless interface
       physical id: 1
       logical name: wlan0
       serial: 00:90:4b:46:e7:a8
       capabilities: ethernet physical wireless
       configuration: broadcast=yes multicast=yes wireless=IEEE 802.11g

It appears as though my wireless card is disabled, though I'm not sure if that is the case.

It appears as though my wireless card is disabled, though I'm not sure if that is the case.

This info now (assuming it is a PCI wifi card):

lspci

[Whiffle]

Just on a hunch, try "ifconfig wlan0 up", then try the iwlist command again.

[jimjesus]

The lspci command output:

It's a laptop, so I don't know if it is a pci wireless card or not.

When I tried ifconfig wlan0 up it said:

SIOCSIFFLAGS: Permission denied

[Whiffle]

Oh I'm sorry, I should have said

sudo ifconfig wlan0 up
