Wireless - ipw2100 on laptop

Hello there, I'm a new arch user and I'm having trouble setting up the wireless on my laptop. I followed the guidelines on the wiki but it still doesn't work, so I would appreciate it if someone could help.

I disabled the router's protection, so I know it has nothing to do with that.
Wireless: ipw2100
I installed wireless_tools and the ipw2100 firmware.

iwconfig:

eth1      unassociated  ESSID:off/any  Nickname:"ipw2100"
          Mode:Managed  Channel=0  Access Point: Not-Associated   
          Bit Rate:0 kb/s   Tx-Power:16 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          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

rfkill:

0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

First, the manual way:

rc.conf:

# Wireless: See network profiles below
#

#Static IP example
#eth0="eth0 192.168.0.2 netmask 255.255.255.0 broadcast 192.168.0.255"
eth0="dhcp"
eth1="dhcp"
INTERFACES=(eth0 eth1)
#WIRED_INTERFACE="eth0"

# Routes to start at boot-up (in this order)
# Declare each route then list in ROUTES
#   - prefix an entry in ROUTES with a ! to disable it
#
gateway="default gw 192.168.0.1"
ROUTES=(!gateway)
###
DAEMONS=(syslog-ng dbus network netfs crond !net-auto-wired alsa)


ifconfig eth1 up
iwconfig eth1 essid "BELL952"
iwconfig eth1

eth1      unassociated  ESSID:"BELL952"  Nickname:"ipw2100"
          Mode:Managed  Channel=0  Access Point: Not-Associated   
          Bit Rate:0 kb/s   Tx-Power:16 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          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

Note that it says unassociated. I'm not sure if this is normal...

dhcpcd eth1

dhcpcd[2056]: version 5.2.9 starting
dhcpcd[2056]: eth1: broadcasting for a lease
dhcpcd[2056]: timed out

iwconfig eth1 channel auto

Error for wireless request "Set Frequency" (8B04) :
    SET failed on device eth1 ; Operation not supported.

I also tried wicd, it blocks at the "Obtaining IP address" step.

rc.conf:

# Wireless: See network profiles below
#

#Static IP example
#eth0="eth0 192.168.0.2 netmask 255.255.255.0 broadcast 192.168.0.255"
eth0="dhcp"
eth1="dhcp"
INTERFACES=(!eth0 !eth1)
#WIRED_INTERFACE="eth0"

# Routes to start at boot-up (in this order)
# Declare each route then list in ROUTES
#   - prefix an entry in ROUTES with a ! to disable it
#
gateway="default gw 192.168.0.1"
ROUTES=(!gateway)

I hope I gave enough information, thanks in advance!

Re: Wireless - ipw2100 on laptop

I think you've got your iwconfig and ifconfig commands the wrong way around. Configure your wireless with iwconfig and then bring the interface up with ifconfig. Then dhcp as you have been trying to do.

Note that your output from iwconfig eth1 was all wrong (lots of zeros:)), nothing was going work after that.

Re: Wireless - ipw2100 on laptop

Try reloading the ipw2100 module.

Just how did you install the firmware btw?

Re: Wireless - ipw2100 on laptop

Thanks for the answers!

JamesKitson: Yeah, I think that's where the problem comes from. Concerning the commands, I followed the steps on the wiki, so I think they are correct.

Mr.Elending: I installed the firmware with pacman -S ipw2100-fw, a query to the local database shows that it is properly installed.
I reloaded the module with:
rmmod ipw2100 (the led indicator turned off)
modprobe ipw2100 (the led turns on)
And redid the steps, but with still the same results.

On the wiki they say something about the radiotape interface. I don't know what that is, but I tried to enable it:
modprobe ipw2100 rtap_iface=1

FATAL: Error inserting ipw2100 (/lib/modules/2.6.36-ARCH/kernel/drivers/net/wireless/ipw2x00/ipw2100.ko): Unknown symbol in module, or unknown parameter (see dmesg)
