Wireless not working

[rhb]

I installed Wubi on an acer ferrari 4000 laptop. It works ok except I can't connect to the wireless internet. I checked the switch in both settings and verified that it worked unchanged in Win 7. I got an error message with the ifconv command; console output follows. If you need more info, I would appreciate having a list of commands to get it. Thanks for the help.

Console output:

(missing file. sudo ifconv wlan0 up got error.
<something> not found.
I a gain to get the output and edit this post.)

The command you are thinking of is ifconfig, not ifconv.

I think what you mean is "ifconfig" not ifconv. For issues with your wireless card, first consult the Ubuntu Wireless Troubleshooting Guide. I'm betting that at some point you'll need to find which driver is appropriate for your wireless card and that may need to be changed. I know I had an Acer before and they had a linux driver that you could download.

Too many editors, too many reboots, posting using an OS that wouldn't know an ifconfig command from a hole in the wall. Anyway, here's the output:

I will check the troubleshooting guide. If that doesn't help, maybe the name of the missing file or directory will, or I can post some log entries if needed. Thanks for your quick responses.

Can you also verify the Acer site with your model number and see if there's a Linux driver?
