ubuntu 12.10, broadcom4313 "device not ready"

**learst** · October 19th, 2013

Hello,

I've been using ubuntu12.10 for a few months, and everything seems to be working fine. Bout a week ago, I started having some problems with my wireless network. The connection keeps dropping for some reason, and I changed the MTU, disconnect/reconnect etc, and changing the network manager to wicd (have since reverted back to gnome-network manager).

Recently though, after disconnecting the wireless (of if it gets disconnected by itself), I can't reconnect. Right-clicking on the wireless icon - it says "device not ready". If I reboot the computer, it's automatically connected. I don't want the hassle to restart my laptop each time it gets disconnected or if I want to reconnect/disconnect.

*I have to note that just this morning it got disconnected, and "device not ready" appearead. I was about to restart my laptop but noticed the website finished loading. So apparently it reconnected by itself, though the wireless icon looks like it is turned off.

Here's some info and things I've tried:

Code:

And oh, I'm running ubuntu 12.10 on a macbook pro. Thanks for your help!

Hope this information helps. Thanks!

Change the encryption mode to pure WPA2-AES (CCMP) in you router interface. Also a fixed channel and 20MHz bandwidth instead of 20/40MHz.

**learst** · October 19th, 2013

Thing is I lived in a shared apartment, so it's not easy to make those changes to router.

Anyway, how does that solve the problem of the "device not ready" after disconnected? Isn't that a problem with my Ubuntu?

**praseodym** · October 19th, 2013

No, its coming from mixed encryption. Try Wicd instead of the network-manager:

Code:

wget http://www.elektronenblitz63.de/download/wicd-1.6.x_addon01441.tar.gz
sudo apt-get install --reinstall wicd
tar xvf wicd-1.6.x_addon01441.tar.gz
cd wicd-1.6.x_addon01441
sudo ./install_wicd_addon
sudo service network-manager stop
sudo killall wpa_supplicant
sudo service wicd restart

Choose wlan0 as interface name and wext as driver

Well I managed to change the encryption mode to pure WPA2 (CCMP), but could not find any settings change to 20 Mhz bandwidth. Hopefully my connection is more stable now.

I also reinstalled wicd as suggested above. I have no idea though how to set the wlan0 and wext thing?

Using wicd, I could disconnect and reconnect now. Thanks!

**learst** · October 23rd, 2013

Well, the wicd didn't last very long. In fact it feels worse now.

Although I remain "connected", after a while I can't load any web pages. And this can be fixed just by disconnecting/reconnecting. This could happen after a few hours, or just within minutes.

It shouldn't be a problem with my connection as I don't have a problem on Mac OS on the same macbook that I'm running ubuntu with.
