Thread: struggling with wireless setup
struggling with wireless setup
user name
 2008-03-26 22:24:12 
Hello.

My wireless USB network adapter (Dell TrueMobile 1180,
413c:8100) is a
802.11b compatible product. Currently in our office we use a
wireless
gateway. The gateway can be configured with a web interface
and it has
two modes: 802.11g mode and 802.11b mode. Currently it is on
802.11g mode.

I tried to follow this guide on wireless setup:

htt
p://gentoo-wiki.com/HOWTO_Prism2_USB_on_Gentoo

And end up cannot obtain IP address. I think it maybe
because I use a
802.11b device trying to connect to 802.11g network. Does
802.11g
network allows 802.11b device to join? If I switch my
gateway to 802.11b
mode, I am afraid I would have slowed everyone else down.

Here is how I tried to connect (I have configured wlan.conf
and
wlancfg-HBF to use WEP/opensystem and 10-digit Hex key, the
authentication method and key are the same as everyone else
in the office)

rootesmeralda:/etc/conf.d# wlanctl-ng wlan0
lnxreq_ifstate ifstate=enable 
message=lnxreq_ifstate
  ifstate=enable
  resultcode=success
rootesmeralda:/etc/conf.d# wlanctl-ng wlan0
lnxreq_autojoin ssid=HBF authtype=opensystem
message=lnxreq_autojoin
  ssid='HBF'
  authtype=opensystem
  resultcode=success
rootesmeralda:/etc/conf.d# dhcpcd -d wlan0

P.S. If linux-wlan has a tool that I can use to scan
available networks
to join, then I think I should be able to tell if it's not
possible for
me to join 802.11g network by myself.

I b client can join a g gateway, since g is backwards

I dont see you issuing the commands to set the WEP key - so
it looks
like you are attempting to join without setting the
authentication.

Dear Karl Relton (and everyone)

Thank you for your help! In fact I think I am too stupid to
fight the
authentication stuff so I take it to the home wireless
network, SSID is
"netgear" and is completely not encrypted. I can
directly connect to
this network without a password by using both SuSE Linux and
Windows (on
a notebook with built-in wireless support) through a
graphical user
interface. The signal quality is good because I am sitting
only 5 meters
away from the AP.

Now back to test the USB wireless adapter. I tried to use
the simplest
configuration, that is, only change on line in wlan.conf
(a.k.a. make
SSID_wlan0="HBF"), and copy wlancfg-DEFAULT
directly to wlancfg-netgear.
I also made sure the device is properly detected:

zhangweiwuesmeralda:/etc/wlan$ sudo lsusb
Bus 001 Device 005: ID 413c:8100 Dell Computer Corp.
TrueMobile 1180
802.11b Adapter
Bus 001 Device 001: ID 0000:0000 

and the module was properly loaded
zhangweiwuesmeralda:/etc/wlan$ sudo lsmod
Module                  Size  Used by
snd_pcm_oss            51264  0

prism2_usb             79404  0
p80211                 33488  1 prism2_usb

(note the prism2_usb module was loaded automatically after I
plugin the
device)

Then I join the network through the most standard way:

This is not what should happen. I should get 10.0.0.6 as IP
address. I
don't understand the error messages, can someone point out
what has been
wrong?

If your SSID_wlan0="HBF" then your config file
should be called
wlancfg-HBF.

try running iwlist to see if the card has found any
networks.

Getting these cards setup the first time can be a bit
tricky, so don't
panic.

It does work with udev & NetworkManager if you prefer a
GUI to set
things up. You'll have to check your distro to see if
NetworkManager is
installed & enabled.

HTH

Thank you for correcting this. In fact, what I did is right,
what I
wrote is wrong.

I made SSID_wlan0="netgear".

wlan0     Interface doesn't support scanning.

(I thought I got this result because linux-wlan-ng doesn't

Is it? Then I'll certainly give it a try. Thanks very much
