Re: error to load driver

Joerg, thank you very much for your tip. I got through the driver loading 
problem by replug the USB adapter or do a cold boot.

However, I was still not able to make through the whole process, though I am 
getting closer. Here is the new problem:

After I loaded the driver and configured it with <iwconfig>, I was able to 
ping my Linksys USB11 ver. 2.6 with the following command: <ping 
192.168.1.1>. All the packets are received. However, when I tried to ping an 
outside address <ping 64.68.82.204>, I got error message:

connect:network is unreachable

That IP address is actually where google is, and it worked when I tried to 
ping it on Windows.

Here is background info:

1. After loading driver, in the syslog, <dmesg> returns following info:

at76c503.c: firmware version 1.101.4 #84 (fcs_len 4)
at76c603.c: device's MAC 00:06:25:0e:10:1e, regulatory domain FCC (U.S) (id 
16)
divert: allocating divert_blk for wlan0
at76c503.c: registered wlan0

(I believe it is good so far.)

<lsmod> returns the following:

at76c503_rfmd   40320   0 (unused)
usbdfu               9324    0 [at76c503_rfmd]
at76c503           53888   0 [at76c503_rfmd]

(I believe it is good as well.)

2. after configuring driver, <iwconfig wlan0> returns the following info:

wlan0 IEEE 802.11-DS ESSID:"faosjtu" Nickname:"okuwlan"
Mode:Managed    channel: 6     Access Point: 00:06:25:B6:0B:41
Bit Rate:11Mb/s
RTS thr=1536 B Fragment thr=1536 B
Encryption key:B38D-D7B4-EF66-7CA1-0820-E2D6-71  mode: restricted
Power Management:off
Link Quality:0  Signal Level:27  Noise Level:0
Rx invalid nwid:8   Rx invalid crypt:0   Rx invalid frag: 0
Tx execssive retries: 0   Invalid misc: 0    Missed beacon: 0

("Link Quality:0" makes me suspicious, though I am not exactly sure what it 
means.)

3. <dmesg> return the following lines after I set <iwpriv wlan0 set_debug 
0x180003>:

at76c503.c: wlan0:PRIV_IOCTL_SET_DEBUG input 9: )x180003 -> x180003
at76c503.c: wlan0:PRIV_IOCTL_SET_DEBUG, old 0x0 new 0x180003
at76c503.c: wlan0: netif running 1   queue_stopped 0   carrier_ok 1

(somewhere in the mail archive I learned that I should expect keylen and 
index displayed here in some "param:" line and they must be 13 and 0. So 
something is wrong in my case.)

4. <route -n> returns following:

Kernel IP routing table
Destination        Gateway       Genmask            Flags Metric Ref Use 
Iface
192.168.1.0      0.0.0.0         255.255.255.0    U     0        0    0    
wlan0
169.254.0.0      0.0.0.0         255.255.0.0        U     0        0    0    
l0
127.0.0.0         0.0.0.0         255.0.0.0            U     0        0    0 
    l0

5. In order to verify that my configuration is correct, I did the following 
experimentation:

(1) replace "faosjtu" with a wrong string for "essid", <dmesg> reports 
"essid didn't match".
(2) use "faosjtu" for "essid", but set "key" to "off", <dmesg> reports 
"requires encryption".
(3) use "faosjtu" for "essid", but set "key" to some wrong value, <dmesg> 
reports:
"state 6->2 (AUTHENTICATING)
state 2->3 (ASSOCIATING)
state 3->7 (CONNECTED)
connected to BSSID 00:06:25:b6:0b:41"
(4) use "faosjtu" for "essid" and set "key" to the correct value, <dmesg> 
reports exactly the same thing as in step (3). (This seems odd to me.)

I also tried to ping the router and yahoo during the above 4 steps. In ALL 
steps, I was able to ping the router correctly, but got the same "network 
unreachable" error in the latter. (this also seems to be odd to me.)

6. I tried to disable WEP in the router and set "key" to "off" in 
configuring the driver, still to no avail.

So I am stuck again. Any advice? Thanks in advance.
