2. What I can do: Connect to unsecured signal - both guest signal anytime and removed security mode WPA-personal
3. Router security: Security Mode: WPA-Personal, WPA Mode Auto(WPA or WPA2)

OS: Windows 7
1. Connects to both guest mode and secure wireless properly
2. Speed n connection

Varun,
Since the original post, 2 non-pae computers have had LUBUNTU installed and both login to the system properly (first try).
This computer is 64 bit and had a wireless driver added (not necessary on the 2 non-pae computers) using additional drivers from the menu. Only one wireless driver appeared on the additional drivers menu.

Thankd for your help.

I assume the new installations are also the latest supported versions of Lubuntu, using kernel 3.11.

Your above installation is an older one, which is using an older kernel despite being updated regularly.

Without going into possibly confusing details, I would suggest to purge the sta driver (that comes from "Additional Drivers") and install either the latest kernel as suggested here (this link also explains why you still have an older kernel), or just the driver from one of the latest kernels.

If you are happy with everything else in the current installation, I would recommend you install only the driver instead of upgrading the whole enablement stack. Here's how -

1) Open a terminal (Ctrl-Alt-T) and install the basic requirements first -

Code:

sudo apt-get install linux-headers-generic build-essential

2) Download the "backports-3.12.8-1" package from here : http://drvbp1.linux-foundation.org/~...tml/backports/

3) Right-click the downloaded package > click "Extract here".

4) Assuming the package has been downloaded and extracted in the "Downloads" directory within your 'Home' directory, compile and install the driver with the following commands in terminal -

Code:

cd Downloads/backports-3.12.8-1
make defconfig-brcmsmac
make
sudo make install

Watch out for errors, report back if there are any.

If the above procedure finishes smoothly without errors, purge the sta driver -

Code:

sudo apt-get purge bcmwl-kernel-source

Reboot and test the connectivity.

PS:
I don't understand why your /etc/modules file is showing so many duplicate entries of "lp" and "rtc". Although they are not related, I recommend you delete the duplicate lines. They should be listed only once.

Also, it would be a good idea to delete your current udev rules file for network rules, after purging the sta driver -

Code:

sudo rm /etc/udev/rules.d/70-persistent-net.rules

It'll be automatically regenarated when required, with only relevant entries this time.

Varun,
I could not make this work, it is the same as before (works on unsecured but not on secure system. Rechecked security and both the modem and computer are set on WPA & WPA2 Personal as well as rechecking the password. Between computers and operating systems functioning on the secure wireless, of which there are 6 including windows 7, windows xp, Lubuntu.
I recorded the installation for you to read.

Code:

Note:
You may or may not need to update your initramfs, you should if
any of the modules installed are part of your initramfs. To add
support for your distribution to do this automatically send a
patch against "update-initramfs.sh". If your distribution does not
require this send a patch with the '/usr/bin/lsb_release -i -s'
("Ubuntu") tag for your distribution to avoid this warning.

Your backported driver modules should be installed now.

Please post the current report of wireless_script. And if by "WPA & WPA2 Personal" you mean "WPA/WPA2" mixed mode in the router, please change it to pure WPA2 only with AES (CCMP), avoid TKIP. This has to be done in the router, not in Ubuntu (Ubuntu will automatically change to what the router offers). Reboot the router after saving any changes.

If you can access the wireless card, also check its antenna contacts to make sure they are not loose.

Varun,
Included are screen shots of the D'Link wireless security settings and Ubuntu settings. All the other setups work with this arrangement.
Also, included is the wireless script output.

As the description in your router's web interface suggests, please change the encryption type to pure WPA2 with AES (CCMP). WPA uses TKIP, so avoid both. Leave the settings in Ubuntu as they currently are.

Apart from that, some suggestions based on the wireless_script report -

1) Turn the "Power Management" on the wifi "off", and make sure it remains off. To turn it off -

Code:

sudo iwconfig wlan0 power off

To check its state -

Code:

iwconfig

Check it a few times within 20-30 minutes to make sure it remains off. If it turns back on automatically, we may try a few additional tricks to keep it off.

2) Keep the ethernet cable unplugged while trying to connect to wireless. By default Network Manager may not attempt to connect wirelessly if a wired connection is detected.

3) The module "ssb" is loading for some reason while it shouldn't. Blacklist it to prevent from loading (with "b43" for additional precaution). The following command will do it -

Code:

echo -e "blacklist b43\nblacklist ssb" | sudo tee -a /etc/modprobe.d/blacklist.conf

4) The "NetworkManager.state" file is showing "WirelessEnabled=false", which means the wireless is disabled in Network Manager's drop-down menu. Please make sure it is enabled there (there should be a tick mark before the "Enable Wireless" option in NM menu). Probably this is the first thing you should cross check. If it already seems enabled, check the file again with -

Code:

cat /var/lib/NetworkManager/NetworkManager.state

Does it still show as "false" in the above output? If yes, try manually changing the value to "true". Let me know if you need help with that.

If none of the above could help, could you please try a Live session of whichever latest ISO you have (I guess from your previous post that you should have the latest ISO of "Lubuntu")? I would be interested to know how it performs with kernel 3.11 or later. If it behaves well, we can manually upgrade your kernel and hope for the best.

Varun,
Changing the security settings on the router, as you requested, made the wireless system work properly. For your information, included are screen shots of the router security settings - before and after.
Thanks for your great instructions and help.
