RE:error to load driver

Hi, I am happy to report that I have figured out the problem(s) I posted a 
couple of days ago. No my Linksys WUSB11 ver2.6 is working great. So I can 
send out this email from Linux. ( I still have a minor problem, which I will 
post in a new thread.)

The problem is a trivial mistake I made in driver configuration. But it 
suggests how difficult it is to make a correct guess without full 
understanding. Just in case it is helpful for other newbies like me, I 
detail my mistake below.

After my driver is loaded correctly, I used "iwconfig" to configure the 
wireless interface. Then I entered command "ifconfig wlan0 192.168.1.1" to 
bring up the interface. However, "192.168.1.1" is the ip address for my 
router. The correct ip address assigned by DHCP, which I found out later 
from win2000, is "192.168.1.100". Once I changed this command to "ifconfig 
wlan0 192.168.1.100" and also added gateway to the routing table with "route 
add default gw 192.168.1.1", everything starts to work perfectly.

I thinks this also explains why when I configure the interface with a wrong 
essid/key combination, "ping 192.168.1.1" always works . Since I mistakenly 
specify "ifconfig wlan0 192.168.1.1", I was effectively pinging the 
localhost, without sending any packets to the gateway. (Please correct me if 
my understanding is wrong.)

Any way, thanks a lot to those who replied to my post. I am almost there to 
bid farewell to windows.

Luke
