Greetings!
It's my first post here, as I've always found everything I've needed already answered for me 
Anyway, the problem:
I'm running a dual boot XP/2.6.11-r3 on a Dell 700M. I use the ipw2200 1.0.3 driver for my wireless radio. When I use XP, I find multiple AP's within range using NetStumbler...
http://www.teammt.com/aps.jpg
But, when I use nix, I only find the one that I'm connected to:
| Code: | crib / # iwlist eth1 scan
iwlist eth1 scan
eth1 Scan completed :
Cell 01 - Address: 00:0F:66:53:B1:26
ESSID:"Hamilton"
Protocol:IEEE 802.11bg
Mode:Master
Channel:11
Encryption key:off
Bit Rate:54 Mb/s
Extra: Rates (Mb/s): 1 2 5.5 6 9 11 12 18 24 36 48 54
Quality=62/100 Signal level=-63 dBm
Extra: Last beacon: 9ms ago
|
I know it's whatever I'm connected to, because sometimes I'll get a lease from Hamilton, sometims from NETGEAR. And, the corresponding AP is listed when I do a iwlist.
The kicker is, neither Hamilton nor NETGEAR are mine (I'm Paradox  ). I can connect to my AP if I set things up manually, but I'm more curious why the scan doesn't have accurate results.
Thanks! |

Hmm that's odd, are you always trying it as root? I did find this part interesting from the man page:
| Quote: | Triggering scanning is a privileged operation (root only) and
normal users can only read left-over scan results. |
Maybe you are seeing results leftover from an old scan? |

Unfortunately that wasn't the problem.
It gets even weirder. I borrowed my neighbor's D-Link DWL-G630, config'd it with ndiswrapper, and the same thing happened. I would get a lease from a random AP (which is fine), but whenever I would try to scan, I'd only get the one I was connected to in the list.

I'd sincerely like you to try "iwlist eth scanning" -scanning-. Keep us posted. Not saying it makes a difference though, but I always feel like it comes up with more aps when i du scanning. Might be my imagination, when i come to think about it.
You can try changing your wireless card's sensitivity "iwconfig eth1 sens #" (man page for details)

| How are you telling it which AP to connect to? |
