Bad Password Asus-n13

[max1e6]

Followed all the posts to configure. I'm fairly confident I got it right. Network manager shows my wireless ssid connection just fine (also shows using wicd, with all green bars).

When I try to connect to my network it struggles for a while then pops-up with "Bad Password". (I positively have the password entered correctly.) This has been reproduced in two separate machines (Lucid & Natty). It has also reproduced on the Lucid machine after a reinstall.

So, I decided to wepcrack the connection and I found that when I monitor my wireless network ssid, it repeatedly dropped-out... failing to secure a handshake. Again, my signal is very strong.

Although it's of no use to me, this adapter connects without a glitch on Windows.

I saw a similar post @ thread t=182398. No resolution there.

Any ideas?

Hi,

network-manager and wicd dont work in parallel. Deactivate NM, login again and try it again. Does your router work in DHCP-mode? Firmware is up-to-date?

You might want to take a look at post #5 on the following thread if you are getting "Bad Password" errors (and you are certain that your password is correct- including CaSE).

Network-manager completely uninstalled. WICD installed.

Tried the other fixes in the recommended post.

Still see the network with the usb but "bad password."

Then, turned off, removed usb, installed an old pci wireless. It finds network and connects. Same password.

I've been reading about all sorts of issues with various USB wireless interfaces under Ubuntu lately. The fact that the old PCI wireless card worked relatively painlessly leads me to believe there is a bug, conflict, disconnect, or 'void' in your ASUS N13 USB driver module with either the wpasupplicant or wireless-tools packages somewhere in the router authentication process. I'm not certain why that is manifesting as a "bad password" though- perhaps that is the 'default case' when wpasupplicant gets confused and/or times out.

For the benefit of Ubuntuforums readers, here are links to some of the documentation and packages involved. It might be worth re-installing those 2 packages to see if that somehow helps get connected. I'd also consider contacting the wireless interface manufacturer, but Broadcom and Realtek are the only 2 OEM's that have reasonably good wireless support from what I've seen personally.

After reviewing posts in this and other forums it is clear that this device can be configured with certain distributions running certain kernels. Setup and configuration varies considerably. There are many posts where a user lost the device when upgrading kernels or distributions. If you mix and match your intuition and selected recommendations, you can often stumble upon a workout. Performance is marginal.

I pulled out several old and new Ubuntu install DVDs and installed them in VBOX machines. Sure enough, if you reproduce the kernel and distribution of a poster's machine, you can fly the device using some modification of his/her recommendations... failing utterly in most other cases. Sometimes WICD works, sometimes not. Sometimes versions of installed packages have to be forced to earlier versions. In recent kernels the native rt2870sta works. Other times installing 3rd party drivers works but you will need to edit several files before the make and move/rename files afterwards. Performance is never very good.

For example in a Natty VM, use the native rt2870sta, blacklist rt2800usb and rta2x00usb, and see t=1419504&page=6 post 58. This produces a working device with network-manager. You can obtain a marginal connection provided your signal is strong. The latency will be poor (pinging the router with 64 bytes will take 50 to 3000 ms... a Windows XP VM will take 0.5 to 5ms). Tweaking the limited iwconfig options will be unsatisfying. There will be no rt2870sta.dat file to edit.

I could fly this device on a native install, but why bother. It's a great Windows device but it's not ready for Ubuntu primetime. I'm not mad though. Where else can you get 4 or 5 days of fun for $30. If you just want to use a wireless usb then avoid this one.

Hi max,

If you still have that Asus-n13 nearby, could you plug it in, restart ubuntu, and paste the output of the following commands if/when you get time (the diagnostic output might help someone here on the forum eventually):

lsusb
ifconfig
iwconfig
dmesg | grep rt28
nm-tool
sudo lshw -C network
sudo iwlist scan
cat /etc/lsb-release
cat /etc/modules
rfkill list all

EDIT: More as a note to myself, here is the Wicd forum (but I don't have an account there yet):

Here's the output from the Natty VBOX machine (that is connecting poorly). (Minor edits made to suppress false images.) Let me know if somethings amuck.
