These are the steps I am performing:
1) ifconfig eth0 down
2) ifconfig lo down
3) [root@ntclap4 root]# iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
4) Push the wireless card into its slot.
5) [root@ntclap4 root]# iwconfig ath0

No DHCPOFFERS received.
No working leases in persistent database - sleeping.
Seems to be the access poing DHCP server is not responding or possibly not
getting the DHCPDISCOVER. Why is the Tx-Power off in the iwconfig ath0
response?
12) Here is the contents of ifcfg-ath0
[root@localhost network-scripts]# cat ifcfg-ath0
# Please read /usr/share/doc/initscripts-*/sysconfig.txt
# for the documentation of these parameters.
ONBOOT=yes
USERCTL=no
PEERDNS=no
GATEWAY=
TYPE=Wireless
DHCP_HOSTNAME=
IPADDR=
DEVICE=ath0
HWADDR=00:20:a6:4c:c1:f3
BOOTPROTO=dhcp
DOMAIN=
NETMASK=
ESSID=NTCOIS1
CHANNEL=1
MODE=Managed
RATE=Auto
Does this look ok?
13) Again I believe the access point DHCP server is working fine since it
works with the Windows XP wireless configuration.
14) Why are all of the TX/RX errors occuring?
