Used ndiswrapper, but wlan0 won't find networks[SOLVED]

Hi all, brand new arch newbie here. I just installed it.

So, I'm having a bit of a trouble with my wireless. My wireless card is

Network controller: Broadcom Corporation BCM94311MCG wlan mini-PCI (rev 02)

I used ndiswrapper (with bcmwl5.inf driver) to get a wlan0. iwconfig gives:

wlan0     IEEE 802.11g  ESSID:off/any  
          Mode:Managed  Frequency:2.462 GHz  Access Point: Not-Associated   
          Bit Rate:54 Mb/s   Tx-Power:32 dBm   
          RTS thr:2347 B   Fragment thr:2346 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

Good so far, right? But now

[Joe@Arch ~]iwlist wlan0 scan
wlan0     No scan results

Trust me, there IS a network out there I can get to it using ubuntu on my other partition. Do you guys have any idea why it can't find any networks?

I've searched these forums, and there are other threads with a tantalizingly similar situation, but none of those solutions have worked for me

EDIT: should I be trying one of those network managers? If so, which one?

that is because you have to run iwlist wlan0 scan with sudo, running it without sudo will just give you the results you once found by running it with sudo, i guess you never did that, so no results

Oh man I'm a huge tool.

Well, thanks for pointing out my mistake

That solved my problem, in sofar that now I can find access-points.

But sudo iwconfig wlan0 essid xxx key xxx isn't letting me connect =/  I'm running lxde, and the network manager here in my taskbar (dunno what it's called) sees the access-points and lets me enter the key, but doesn't connect

Well, I'll keep giving it a shot.

Here's the actual commands:

[joe@Arch ~]$ sudo iwlist wlan0 scan

EDIT:

Solved my own problem. I ended up installing wicd to manage my networks. At first it still couldnt' connect, but the GUI gave me the ability to say what sort of encryption it was (wep hex) and it worked once I did that.

Does anyone know how to do that through the CLI?
