Wifi stops working intermittently during active usage and *always* after screen off. Syslog shows this message just before it happens: kernel: [ 4832.867113] wlan0: AP XX:XX:XX:XX:XX:XX changed bandwidth, new config is 2412 MHz, width 1 (2412/0 MHz) This happens regularly. I have tried some tweaks suggested to users facing wifi problems in Ubuntu 14.04. My iwlwifi.conf is this: # /etc/modprobe.d/iwlwifi.conf options iwlwifi bt_coex_active=0 swcrypto=1 11n_disable=8 This does not solve the issue.
