[SOLVED] Wireless [WiFi] in ubuntu 9.10-10.04

I just bought a new laptop. OK I had the similar problems. The network applet shows “Device not Ready”. Then all the technique that was shown in the Ubuntu forums was not helpful. The solution was not that big as the big is the problem. And with the similar solution, I helped my 2 friend’s with the same.

Requirements:

1. Your Laptop/PC
2. Internet Access
   This is required to install the drivers. Or may not be required in another process as shown below

You have your PC/Laptop and you have the problem, So I hope that you have the Wireless problem. Here is the thing you can do:

• Goto your Administration>Hardware Drivers
• Then it searches for the missing drivers.
  Install + Activate the missing Wireless Driver from you existing INTERNET.

But what if I am not able to use INTERNET at any cost in my Ubuntu?

Then this is the thing you got to do:

• Goto your Administration>Hardware Drivers
• Then it searches for the missing drivers.
• Click on Activate by selecting your wireless device.
• Then it tries to download the files that are required for the installation of wireless.
• But click Cancel.
• It gives you the error log in the same window.
• Then select all and copy in some text editor.
• After that get only the URL part, i.e. the Debian file part.
• Save the file and get the file from a place where INTERNET is available.
• I don’t need to say the process to download the files.
• [NOTE] Sometimes you may see multiple driver activation (As far from my one friend’s), you may repeat the similar steps and get your Wireless active.

[MORE:] Some of the people might be so lucky that they have already the drive installed but might not be active.

What to do with those files?

You need to run Ubuntu again after you download and run the debian file.  Then it will install all the requirements that you need. But make sure if there are multiple files to be installed, there might be the condition to manage the order to install. Don’t  worry about the order, the installer will itself guide the order.

If you get the problem continuously try this:

• Open this /etc/modprobe.d/blacklist-ath_pci.conf in root mode in text editor.
• Then keep a “#” sign in front of your device. Like: “#blacklist ath_pci” in case of mine.
• The above file may not be existing in case of yours. The file name might be in the name of your device.
• Just a simple reboot and in terminal “sudo ifup wlan0“.

Well nothing’s works for you? If no just buy a router and connect to INTERNET and then connect it via cable.

Have fun with the INTERNET.
