WUSB600N + WPA and Windows 7 RC1
I recently updated my personal Media Center PC to the latest build of Windows 7 Ultimate. Upon upgrading, my Linksys WUSB600N Ver1 USB dongle stopped working. Well, let me specify…
Explanation:
Windows 7 did recognize the WUSB600N, however everytime I entered my WPA TKIP encryption key it would comeback as incorrect. Upon further investigation, I realized that Windows 7 was thinking that the WPA encrypted network was actually using WEP, which of course was incorrect.
Upon even further investigation, I realized Window 7 was installing the driver for the Version 2 of the WUSB600N. I had the Version 1.
How to fix
- Download the correct driver from http://nmiller.net/downloads
- Navigate to \Windows\System32\drivers
- Find netr28u.sys
- Rename the file to netr28u.old
- Unplug the USB dongle
- Reboot
- Copy the downloaded netr28u.sys to the \Windows\System32\drivers directory
- Reboot
- Plug in the USB Dongle
- The correct driver should now be autoinstalling ENSURE IT DOES NOT SAY INSTALLING “WUSB600N…VERSION 2” It should simple say installing WUSB600N (no version number).
- You should now be able to connect to WPA networks.
Intel 3945ABG, generic kernel 2.6.27 and Update Manager failure
This post refers to the following items:
Lauchpad Bug 285280
Ubuntu Forums Post
I applied a kernel update on October 15, 2008 which somehow didn’t have the updated nic-firmware package installed. Thus, my Intel 3945ABG wifi card stopped working…in the middle of work.
So after a couple minutes of research, I found this nifty little thread in the Ubuntu Forums. Following the instructions on the page, I indeed got my card to work.
Problem:
Upon the release of the next update they included the proper firmware in the package linux-firmware. This fails package updater and Update Manager. When I attempted to remove the package via Terminal I would get the following error:
$ sudo apt-get remove nic-firmware
Reading package lists… Done
Building dependency tree
Reading state information… Done
You might want to run `apt-get -f install’ to correct these:
The following packages have unmet dependencies:
linux-image-generic: Depends: linux-firmware but it is not going to be installed
E: Unmet dependencies. Try ‘apt-get -f install’ with no packages (or specify a solution).
Fix:
Open the terminal and run the following:
# apt-get remove linux-image-generic
# apt-get remove linux-firmware
# apt-get remove nic-firmware
Then run updater and should update.
What was learned:
Packages have dependencies, and installing a dependency may not be the answer. You may need to work backwards. I had to remove all the packages that DEPENDED on nic-firmware before I could fix the problem. Seemed a bit backwards in my mind, but it worked.
