Wifi issues

  • Update wireless drivers:
    • TODO
  • Random Disconnection
    • check "dmesg | grep wlan0" will probably be complaining about "wlan0: deauthenticating from MAC by local choice (reason=3)"
    • Arch wiki hints at solution: Wicd#Random_disconnecting
    • My Solution:
      • Disable power management of pci-express in BIOS
  • Wicd cannot obtain IP address
    • Wicd#Failed_to_get_IP_address
    • Use dhclient instead of dhcpcd:
      • packman -S dhclient
      • Set wicd to use dhclient:
      • in wicd-curse press 'P', select external sources, and then select dhclient

Nvidia Optimus issues


  • Boot up issue with UDEV timeout
    • cat /var/log/boot | grep -i pci reveals udevd[169]: seq 1352 '/devices/pci0000:00/0000:00:1c.1/0000:03:00.0' killed
  • Disable annoying system beep
    • Insert "blacklist pcspkr" into /etc/modprobe.d/pcspkr_blacklist.conf
    • Reboot or rmmod pcspkr
