You might not have enough posts yet to be able to get attachment rights *shrug*.

You can add attachments in the web interface with the "Attach Files" area below the edit box as well. In some instances the toolbar above the text doesn't show for some people. (Skin dependent I think.) But the Attach Files box in the Additional Options area on hitting Quote & Reply to an article is always there.

Edit: StefanL may be right too... I think attaching happens after post 10? Dengo, you may need to post a few times to dummy-up you post count.

So i copy here the outputs of codes

the dmesg output is

wl1251: WARNING WLAN not ready
[ 135.171203] wl1251: ERROR unsupported chip id: 0x0

Please use logs. How is anyone supposed to see what's happening on your machine if you don't provide info?

I would like to see in your dmesg if your wireless module stops being recognized after you try to connect or if it always is.

I have not seen the output of lsmod either.

Sorry I attached my txt files by txt uploader because my posts not enough to attach something.

here is dmesg output :

and here is the lsmod output :

Thanks, that's better.

Could you try removing the module with modprobe by running this as root?

This should remove the wireless module from your kernel.

After that add it back with

the output of modprobe -v -r wl12xx is

FATAL: Module w112xx not found.

Of course, my mistake. If the module wasn't found in the first place, how could we possibly remove it. right?

So, without trying to remove it, have you tried to add the module with the second command?

I am not sure, but something tells me you may have a hardware problem with your N900. Hopefully someone more knowledgable reads the thread here and is able to shed some more light.

when i try to add module it gives me same output

FATAL: Module w112xx not found

Have a look at the following

and make sure there is actually a module file name w112x.ko in the directory.
