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
