Re: ifconfig wlan0 up failed
 

wlano? 0 is zero

Re: ifconfig wlan0 up failed
 

also it should be /sbin/ifconfig IMO if you haven't set expressly the PATH in the /.bashrc file...

Re: ifconfig wlan0 up failed
 

@ codeus ...yeah i know it is 0...by mistake i wrote wlano insted of wlan0

Re: ifconfig wlan0 up failed
 

Could you post the exact output of doing, as root:

# ifconfig wlan0 up

also, run "lsmod" (as user or as root, doesn't matter), and post the output.

Re: ifconfig wlan0 up failed
 

@amank053,

For some reason you don't have the module cfg80211 loaded. Have you tried rebooting and seeing if it works then?

Otherwise, do, again as root:

# modprobe cfg80211

and then try the ifconfig wlan0 up again.

QUESTION: besides wifi-switcher, have you installed and/or played with other wlan-tweaking tools?

Re: ifconfig wlan0 up failed
 

Sir, thnx for your concern.
Yes sir i have tried rebooting. I am not good at this xterminal commands still then i am doing my best.


I tried doing as you said and here is the output.

thnku sir,

Plz Help...:(

Re: ifconfig wlan0 up failed
 

OK that's weird. What kernel are you using?

Can you run this on the terminal (as normal user, no need to be root):

$ uname -a

and then

$ ls -l /lib/modules

and then

$ ls -l /lib/modules/`uname -r`

those above are ``back-ticks`` (or grave accent, or whatever you want to call them).

if you don't manage to run the last command, do this:

$ uname -r

you should see something like "3.2.0-32-generic" (more likely 2.6.28-bla-bla). Then

$ ls -l /lib/modules/2.6.28-bla_bla (i.e. what uname -r returned)

If you post the output of the above commands, we will know which kernel you are running and which modules are available. We can take it from there.

sir plz help...:(

Re: ifconfig wlan0 up failed
 

OK. Apparently the stock kernel doesn't have the cfg80211 module (maybe it's built-in, or maybe it's just not used, I don't know).

One way to get this to work would be to install kernel-power, but the obvious question is first: why do you need to run "ifconfig wlan0 up". Is your WLAN not working?

Re: ifconfig wlan0 up failed
 

i want to use wifi on my phone....my phone does not detect the available wi-fi connections...i dont know the reason behind this....
jst wanted somebody to help...

i think u have understood the problem and just want you to provide the solution....that's all...


thanks for your concern sir...


:(

Re: ifconfig wlan0 up failed
 

Wifi should work in any case (stock or power kernel), and you definitely don't need to do anything with ifconfig.

I guess it's time for a reflash (if in doubt, complete reflash). You haven't played with Nitdroid lately, or?

Re: ifconfig wlan0 up failed
 

Wasn't wifi-switcher deemed broken/unstable a while ago?

I would reflash the kernel.

Re: ifconfig wlan0 up failed
 

sir thnx for your concern.
i am ready to do anything that you will suggest me to do....

let me tell you one thing nearly 6 months ago i sent my phone to nokia care center to reinstall the maemo in it....when i got my phone back everything was deleted from it...i dont know whether they refleshed hi aur what so ever they did....

you please provide me with the solution as what should i do next...
if after reflashing i will be able to use wifi then i am ready to do that thing as well...

you just tell me what to do next...

Re: ifconfig wlan0 up failed
 

no sir i havenot used nitroid...
and i havenot used wifi on my phone for last 1 year....

Re: ifconfig wlan0 up failed
 

To reflash follow the procedure on
http://wiki.maemo.org/Reflash

Re: ifconfig wlan0 up failed
 

After reflashig is it for sure that i will definitely be able to use the wi-fi in my mobile phone...
if YES then i am ready to do so...
or you still need to check some other things in my phone.???

Re: ifconfig wlan0 up failed
 

Yes, you will be able to use wifi after reflash for sure IF its not a hatdware fault. I think you will be fine. Good luck !

Re: ifconfig wlan0 up failed
 

If it is not a hardware fault then yes.
You have no option other then a full reflash to find out.
