hi all,
=20
I'm trying to have my usb wireless dongle (Inventel, based upon an atmel
at76C503 chipset ) work under fedora core 3.
My machine is a bi-pentium 3 with an asus P2B-DS motherboard
I have successively installed both the sourceforge and the berlios =
drivers
None worked !
The final error is always the same : Definition of IP informations for
wlan0. failed.
 =20
Here are the results for the berlios driver, the last I installed. The
driver compiles and install OK.
lsmod returns
 =20
 at76c503_rfmd          46468  0
 at76c503               81760  1 at76c503_rfmd
 at76_usbdfu             9220  1 at76c503
 =20
In the modprobe.conf file, I added :=20
alias wlan0 at76c503-rfmd
=20
iwconfig returns :
 =20
 lo        no wireless extensions.

 The iwconfig man page indicates that an access point address of  =
00:00...
indicates that the 'association between the dongle and the access =
failed.
 Therefore I reviewed the dongle parameters with iwlist
 The results are as follows:

[root@popeye ~]# iwlist wlan0 event

Then I played with the various parameters with iwconfig.
Nothing worked: I always recover the null address for the access point =
at
the end !
=20

I tried to use Fedora graphical tool for network settings, with no =
better
result: I can't activate the dongle

Finally, here is the content of ifcfg-wlan0:
 =20
 # Please read /usr/share/doc/initscripts-*/sysconfig.txt
 # for the documentation of these parameters.

=20
ps : the association of the dongle doesn't work any better is I use a =
fixed
addressing using the masks and address given by MS-Windows, under which =
my
wireless dongle works fine !!!!
=20
I stuck, now :-) ! Could someone suggest me an issue, other than =
throwing
away both the dongle and the access point to buy something working under
Linux ???
