Won't connect to wireless access point unless disconnected then reconnected

[Drivas]

Binary package hint: wireless-tools

Upon startup, will attempt to connect to a preferred wireless hotspot indefinitely. Will only actually connect once "Enable Wireless" is unchecked then rechecked (usually it will connect after this; it will occasionally take a few more tries).
