wlan und routening

[Voyager_MP]

Hier ein kleines script, welches für laptops gedacht ist, und beim systemstart (rcS)
gestartet werden soll um zu proben welche netzwerke verfügbar sind und dann automatsch conneted.

leider bekomme ich das routeing nicht so perfekt hin. wenn jemand helfen will, gerne.

Bin für verbesserungen gerne offen
