mon0 error in airmon-ng on Dell Inspiron 6000 w/ Intel 2200BG wireless

I'm testing my home network's security, and no matter what I try,

sudo airmon-ng start wlp3s3

returns

Found 2 processes that could cause trouble.
If airodump-ng, aireplay-ng or airtun-ng stops working after
a short period of time, you may want to kill (some of) them!

PID	Name
2619	wpa_supplicant
2697	dhcpcd
Process with PID 2619 (wpa_supplicant) is running on interface wlp3s3
Process with PID 2697 (dhcpcd) is running on interface wlp3s3


Interface	Chipset		Driver

wlp3s3		Intel 2200BG	ipw2200 - [phy0]
				(monitor mode enabled on mon0)

mon0: ERROR while getting interface flags: No such device

iwconfig outputs

TELL me how to fix it and I'll be back in a week, same problem.
TEACH me how to fix it, and I'll be good from then on.
Oh, and WHY the fix works would also be appreciated.

Re: mon0 error in airmon-ng on Dell Inspiron 6000 w/ Intel 2200BG wireless

Not all wireless cards can handle packet injection, which will be needed when using the aircrack-ng suite.
Two things stand out:
It appears that you are using your internal wireless card,(Intel 2200BG chipset) which may not support packet injection. Some chipsets won't work at all, some can be patched.
Simple fix: grab a wireless card (usb) from ebay that is known to work. My favorite is the netgear WG111v2, about $10.00 U.S.
It seems you are connected to the internet:

wlp3s3    IEEE 802.11abg  ESSID:"wilrout" 
          Mode:Managed  Frequency:2.457 GHz  Access Point: 00:18:E7:E2:D4:72
You don't want to be connected for this.

The best place to start for you would be http://www.aircrack-ng.org/documentation.html
You can check your chipset and find any patches you may need, as well as follow their tutorials.
You tube also has a lot of video tutorials.
Good luck.

Edit: this may be of interest, note the "mon0: ERROR while getting interface flags: No such device" errors.
