hi everyone! first time poster and i just recently converted my laptop (compal FL90) and i'm happily using ubuntu 64 :P

however, one thing i have problems with is the wifi. i installed a Intel 1030N for wifi + bluetooth, however, as of recently i've been encountering issues with it actually connecting to AP's even when they're in the same room. i have a Cisco 1200 LWAPP just about on top of me at work and i do see SSID's but when i try to connect it asks me for encryption key's again. same with my house, cisco 851W in the same room. i also had a netgear N router with DDWRT at one point and i had the same problems.

sometimes it works, sometimes the wifi vanishes (the network widget disappears from the menu bar) at this time i can still see Wlan0


it was working flawless until i started messing with the Sonicwall Netextender. thats when i really noticed something wrong. i couldnt get it to work and on accident removed LIBSSL.0.9.8 and CRYPTO.0.9.8 i was able to restore them from the lib's under the live disk, and its been up and running very well other than wifi.


ive seen others have luck with upgrading their kernel to 2.6.38 (perhaps i think some were at 10.04 at the time though), turning off power save options, and removing networkmanager.state


what can i do to fix this?
if you need me to post up anything like iwconfig, lspci or whatever let me know.

Hi,

please show:


lsb_release -a
uname -a
lspci -nnk | grep -iA2 net
iwconfig
lsmod
dmesg | grep iwl
If the card is "too new" install a new driver version and/or firmware:

Firmware:

wget http://media.cdn.ubuntu-de.org/forum/attachments/2767012/Intel_Firmware.tar.gz
sudo tar xvf Intel_Firmware.tar.gz -C /lib/firmware

Driver:

sudo apt-get install --reinstall linux-headers-$(uname -r) build-essential dkms
wget http://www.orbit-lab.org/kernel/compat-wireless-2.6/compat-wireless-2.6.tar.bz2
tar jxvf compat-wireless-2.6.tar.bz2
cd compat-wireless-20*
make clean
make
sudo make install
Reboot.

If you update the driver, you may need to compile again after a kernel upgrade:


cd compat-wireless-20*
make clean
make
sudo make install

Looks good, I think compiling is not needed. Update the driver via:


sudo apt-get install linux-backports-modules-cw-2.6.39-natty-generic
and reboot. Check:


iwconfig
sudo iwlist scan
iwlist chan
dmesg | grep iwl

Do you have any connection? If no, here are the needed packages:


http://security.ubuntu.com/ubuntu/pool/main/l/linux-meta/linux-backports-modules-cw-2.6.39-natty-generic_2.6.38.11.26_amd64.deb

Install them by double clicking and reboot.

installed the packages and everything went well, however, still unable to connect to a SSID. i can see them, it asks me for encryption, and nothing afterwards.

Does your router send in b+g+n mode? Intel deactivated N-mode per default, better choose b+g mode in your router.

Maybe you can activate the N-mode via:


echo "options iwlagn 11n_disable=0" | sudo tee /etc/modprobe.d/iwlagn.conf
sudo modprobe -rf iwlagn
sudo modprobe -v iwlagn
but normally you need a newer kernel for that.

no N on my router, just B/G would that matter?

The network "CityHallPublic" seems to be hidden. Is it public? Try to "connect to a hidden network" and/or add the hardware address of the network you want to connect to into the field "BSSID".

its not hidden. all of our network SSID's are broadcasting.

will not work via hardware address or hidden network for BSSID either.

Which network dou you want to connect to? Traffic on Channel 8, identical ESSIDs on Cell 1 and 2. I recommend using different ESSIDs and changing the channel.

i figured out my issue. after running the live disc and encountering the same issues i installed my old B/G adapter in, its a lintel too. wireless works fine. is there a way i can just use the Bluetooth module in the other N adapter? when i have 2 cards in they seem to cancel out each other, i "see" both adapters in the network manager, but cant connect or enable anything.

What card is that? Show the "lspci" output again. The Bluetooth module is USB?

hi everyone! first time poster and i just recently converted my laptop (compal FL90) and i'm happily using ubuntu 64 :P

however, one thing i have problems with is the wifi. i installed a Intel 1030N for wifi + bluetooth, however, as of recently i've been encountering issues with it actually connecting to AP's even when they're in the same room. i have a Cisco 1200 LWAPP just about on top of me at work and i do see SSID's but when i try to connect it asks me for encryption key's again. same with my house, cisco 851W in the same room. i also had a netgear N router with DDWRT at one point and i had the same problems.

sometimes it works, sometimes the wifi vanishes (the network widget disappears from the menu bar) at this time i can still see Wlan0


it was working flawless until i started messing with the Sonicwall Netextender. thats when i really noticed something wrong. i couldnt get it to work and on accident removed LIBSSL.0.9.8 and CRYPTO.0.9.8 i was able to restore them from the lib's under the live disk, and its been up and running very well other than wifi.


ive seen others have luck with upgrading their kernel to 2.6.38 (perhaps i think some were at 10.04 at the time though), turning off power save options, and removing networkmanager.state


what can i do to fix this?
if you need me to post up anything like iwconfig, lspci or whatever let me know.

I had this same exact card.

The 3.0 Kernel carries the proper drivers for it. Intel packs all of their drivers into the linux kernel itself. Every time you get a kernel update, you get the latest intel drivers as well.

NOTE:

On Windows 7 with this wireless card, you must disable all power management for it. You do this in power options and advanced. There is a bug with this card and power management, although on the 3.0 kernel it seems to be unaffected.
