wlan0 No wireless extention for wireless usb adapter - zd1211
Posts: 1
Hello,
I am new to Linux so may be i am doing something wrong or dont know what i am doing..
The problem is i have F3C installed in my desktop and i am trying to configure Hawking Tech HWU54G wireless usb adapter. Made a google search and came to know that i can use ZD1211 driver. Driver installation went fine after that i loaded driver and i can see it running with lsmod.
according to instructions i ran ifconfig where it showed me 4 entries somthing like this lo, eth0, s..0, wlan0. i assume wlan0 is the one i need to configure for wireless. so i ran iwconfig wlan0 and it gave me message " No wireless extension ". i did checked some variable with name CONFIG_NET_RADIO which has value 1.
below is run of ifconfig, iwconfig and lsmod that shows driver is there zd1211
wlan0 entry in the iwconfig comes only when adapter is coneected in the usb.
[root@localhost ~]# ifconfig

For Mepis the manual command

For Mepis the manual command 'ifconfig wlan0 up' will bring up the wireless extensions. Though if one files out the Mepis OS Center networking options the USB wireless will just kick in on boot or 1st plug. But don't unplu it :>) You'll get system USB errors if you do, and you won't be able to replug it.
By the way, I have tried running this driver on the Hawking Tech HWU54G connecting to an AT&T 6850G wireless router. The driver drops the connection on me quite frequently, and sometimes knocks out the wireless router when it fails. Can't even access the router management page from any station after that without rebooting the router. Are you experiencing anything similar?
I'm trying to isolate what might be the cause of this. Maybe its something with the router? In which case perhaps there's a setting on the router I can change. But in any event, although it runs its qjuite impossible to use on a home network given this state of affairs.

When all else fails, read the instructions. The Readme file that came with the source code gives you the commands to get it running manually.
Try these 2 links for some decent documentation:
