wireless stopped working

**waterhead** · 06-21-2009

Well, your wireless seems to be active, it is named eth1. The problem may be with NetworkManager.

Run this command, it will scan for available networks. Post it back if you want, it shouldn't contain any sensitive info.

Code:

 iwlist eth1 scan

You may want to install a different wireless connection manager. If you open the Synaptic package Manager, there are two you can install:

wicd
wifiradar

Wicd is for all wired and wireless network connections. You have to disable or uninstall NetworkManager to use it, if Synaptic doesn't do it for you. Wifiradar is only for wireless, but I have never used it. I just installed it, but it won't run.

Edit: wifiradar needs something called su-to-root to run, but it' doesn't seem to be available.

I was able to run wifiradar, just using sudo.

Code:

sudo /usr/sbin/wifi-radar

Edit: It may be better to start it with this command:

Code:

gksudo -S /usr/bin/wifi-radar

You can actually edit the menu and change the wifiradar icon to use the gksudo command instead of su-to-root.

I sure hope one of these programs gets your wireless working.

I googled the problem, and came up with some info that says you should remove and reload the module. So run these commands:

Code:

sudo modprobe -r wl

Code:

sudo modprobe wl

Code:

ifconfig eth1 up

well,

Code:

iwlist eth1 scan

returns

Code:

eth1      Interface doesn't support scanning.

wicd can't find any wireless networks (and of course there are wireless networks where I am)
wifi-radar returns "eth1 Failed to read scan data : Invalid argument"

and removing and reloading the wl module did not help.

it seems I just can't receive the wireless signal or somthing like that no?
I'm really desperate. I don't know what else can it be other than some hardware problem.

It does seem like the wireless card is broken. The only other thing it could be is a switch that turns it on/off. If you have such a switch, try turning it off and rebooting with it off. Then shut the PC down again, this time turn it back on and then boot up again. Try this several different ways, to see if it will "shake it loose". You can also check your BIOS settings for anything that may affect it. I would try enabling "wake-on-LAN", and see if that helps.

It may be time to look for another wireless card.

well, in the bios I turned the wireless off and then on and still nothing. I guess the card is indeed broken.
I'll put it in repair.
thank you very much waterhead.
when it's out of repair i'll update about what it was.
