 Posted: Thu Aug 18, 2005 6:42 pm Post subject: system won't detect IEEE 802.11b PRISM3 USB |
 |
|
system : Gentoo 2005.1, installed manualy
kernel 2.6.12
i am using a desknote b530 computer, which has a built in USB wifi card
problem is, that i can't get it work, kernel won't even detect it,
i tried different configuration for the kernel, but still nothing
in my opinion kernel doesn't support prism III, there are prism54, but with this module it didn't work either
any help about this
lsusb -v output for USB port where my wifi card is located

beyond os,
Your device is advertised as idVendor 0x124a, dProduct 0x168b there is a howto for 2.4 and 2.6 here
http://www.fuschlberger.net/flybook/?m=13.
I know it says Prism2 but the vendor and product IDs match.
Google for | Code: | | 0x124a +0x168b +linux |
for more hits.

i compiled the module and whe i run
modprobe prism2_usb then its all ok
but when i say
/etc/inid.d/wlan restart
then i get an error that
| Code: | Shutting Down WLAN Devices: Shutting Down WLAN Devices: message=lnxreq_ifstate
ifstate=disable
resultcode=success
FATAL: Module wlan0 not found.
FATAL: Module p80211 is in use.
Starting WLAN Devices: FATAL: Module wlan0 not found.

beyond os,
I dont have wireless but /etc/inid.d/wlan is a script that will use a data file of a similar name in /etc/conf.d/
Reading the script will tell you the names of the data file.
For sure, wlan0 is the logical name of an interface, not a kernel module, if modprobe prism2_usb worked for you, prism2_usb is your module name.

got it working
only problem is getting to the network
interface is up and running(also connected to the accespoint),
but i can't even ping the router
it seems to me that the problem is somewhere in the routing table
and dhcp doesn't work
i got the network up only with static ip and gateway
so this is not a problem when i'm at home, but
i am using a laptop and therefore when i want to connect to the
network somewhere else i must manually change my
network configuration accoding to specific network
anyway i think that this headline problem is solved,
my card is detected and working, so thanks for help
now i just need to read the manuals about networking
and how to configure them right

I had the same problem here. I solved it by writing a script called prism2_usb in /etc/hotplug/usb that contained this:
| Code: |
#!/bin/bash
/etc/init.d/wlan restart
dhcpcd wlan0
|
use chmod to make the script bootable. That way, whenever hot/coldplug loads the prism2_usb module, it starts wlan and then attempts to get a DHCP address for it. This has worked fine for me for the last 3 days. The only problem I had was if i disabled and re-enabled wireless, it would not load again.
Good luck,
