Wifi Disconnects and it is Unable to Reconnect, “device not ready” on Debian and Ubuntu
April 4, 2014 4 Comments
On both Ubuntu and Debian I’ve faced a problem with the Wifi that would get disconnected and would not be able to reconnect. On some circumstances, even brand-new Debian Jessie, Network Manager 0.9.8 would show a “device not ready” message instead of a list of wireless networks.
On both Debian Jessie and Ubuntu 10.04 I’ve solved that by removing and reloading modules, though different modules were targeted.
Ubuntu 10.04 (and it will probably work for newer versions):
sudo rmmod iwlagn sudo rmmod iwlcore sudo modprobe iwlcore sudo modprobe iwlagn
rmmod iwlmvm rmmod iwlwifi modprobe iwlmvm modprobe iwlwifi lln_disable=1 swcrypto=1
