wlan suddenly stopped working ( ubuntu 8.10 )
 
hi, i am running ubuntu 8.10 and i havent ad any problems whatsoever, but in about a few days ago, my wlan stopped working..

i have tried everything(!) but i cant seem to fix it, i have even formatted the entire pc, and rreinstalled the os, so i am really out of answers to what to do next..

i am using a dell xps 1210, with a intel pro wireless card, broadcom chipset..

so, if anyone have a great solution for me, i would really appreciate it..

Did you by any chance do a kernel upgrade just before this happened? It would help to know what was done that caused the interface to stop working. Reinstalling the entire OS seems a bit drastic, unless something else happened that we don't know about.

As root, or using sudo, check:

ifconfig

This will tell you the status of any interfaces that might be working.

iwconfig

Provides status of any wireless interfaces.

lspci

Provides information on the pci hardware devices detected - your wireless NIC should be listed, unless it's USB, in that case try lsusb

lsmod

Will give you a very long list of installed modules. Your wireless driver should be listed.

What driver are you using?

thanks for the response, but i still don`t get why my wlan isn`t working..

and the bigger question is why did my wlan work from the getgo when i installed 8.10, but after it stopped working, and after my re-installation, it did not...

anyways, when i type ifconfig:
##
laptop:~$ ifconfig

typing iwconfig:
##
laptop:~$ iwconfig

all the more confusing, sorry!!

http://bcm43xx.berlios.de/?go=devices this will get you in the right direction . if you were using a ndis wrapper and 810 updated then that is a isuue start over. I will let you know the new kernels 2.6.24 and up have the old bcm43xx blacklisted. why it is not compatable with the new 32 bit runing 64 bit stuff. and I know yours worked before so I guess you better use the ndiswrapper.

Did you try it with any other operating sistem?

I am also running an dell xps, one day we had a small power bump and it somehow changed the last octet in my router by one digit, it had changed from 255 to 254. when it happened it said i was connected but i could not browse. i changed it back and everything was fine.

this is me thinking out loud

min_sin 12-21-2008 07:22 PM

wtf, hardware issue??
 
thanks for the response!!

but in my frustration i installed xp, and my wlan is still non-functional!!

after that, (and after installing the drivers) i flashed the bios, and just when the pc was booting, the indicator for my bluetooth device lit up...

when i got in, i shut down, and i have been trying to launch the wlan radio in every concieveble way, but it wont respond!!

my question in this regards is, is it possible that a "kernel" or another "thingy" in ubuntu could have changed some of the hardware configuration in the extent that it affects my laptop regardless of OS`s??

or is it just my networking card that has finally dicided to have a breakdown after much beating.. =)

oh, and yeah, i will try those links, but that won`t happen 2day!! g`night!
