Subject: WLAN Problems- need solution
Date: Sun, 17 Apr 2005 19:38:19 -0700
I decided to try to finally get WiFi working on my laptop.  My WiFi
Cardbus card appears to lock onto my access point, but I can not ping
the router at 192.168.1.1.  I am using a Netgear WG511T card.  It seems
that no data is getting through.  I am using 128bit WEP.  Here are the
relevant files or outputs.  I would appreciate any help.  Thanks!  Rob

lsmod output.  This looks normal to me.  I had to remove net_ath0 and
put net_eth0 back in so I could send this post.

Here is my wireless-opts file for the MadWiFi driver

# Wireless LAN adapter configuration
#
# Theory of operation :
#
# The script attempts to match a block of settings to the specific wireless
# card inserted, the *first* block matching the card is used.
  # The address format is "scheme,socket,instance,hwaddr", with * as a
wildcard.
# 'scheme' is the pcmcia scheme (set via 'cardctl scheme XXX').
# 'hwaddr' is the unique MAC address identifier of the wireless card.
# The MAC address is usually printed on the card, or can be found via
ifconfig.
# Some examples here use only half of the MAC address with a wildcard to
# match a whole family of cards...
#
# All the Wireless specific configuration is done through the Wireless
# Extensions, so we will just call 'iwconfig' with the right parameters
# defined below.
# Of course, you need to have iwconfig installled on your system.
# To download iwconfig, or for more info on Wireless Extensions :
#    http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html
#
# Note : you don't need to fill all parameters, leave them blank, in most
# cases the driver will initialise itself with sane defaults values or
# automatically figure out the value... And no drivers do support all
# possible settings...
#
# If you make any mistakes, you'll get a cryptic message in the system
# log.  You'll need to figure out on your own which parameter was wrong:
#     cardmgr[310]: executing: './network start wvlan0'
#     cardmgr[310]: + SIOCSIWMODE: Invalid argument
# I've tried to give more troubleshooting help at :
#    http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html#debug
# In case of doubts, just check "/etc/pcmcia/wireless" for the gory
details...
#
# Note also that this script will work only with the original Pcmcia
scripts,
# and not with the default Red Hat scripts. Send a bug report to Red Hat ;-)
#
# Finally, send comments and flames to me, Jean Tourrilhes <jt@...>

Here is my modules-autoload.d file.  Again I had to add "b44" back in to
send this email:

system boots.

# Add the names of modules that you'd like to load when the system

here is my conf.d/net file.  Again, had to switch in eth0 to send this
email:

# This blank configuration will automatically use DHCP for any net.*
# scripts in /etc/init.d.  To create a more complete configuration,
# please review /etc/conf.d/net.example and save your configuration
