 **A:** In "manual" mode travelmate will be triggered solely by procd interface down events, whenever an uplink disappears travelmate tries n times (default 3) to find a new uplink or reconnect to the old one. The 'automatic' mode keeps travelmate in an active state and checks every n seconds the connection status / the uplink availability regardless of procd event trigger.  
 
 **Q:** What happen with misconfigured uplinks, e.g. due to outdated wlan passwords?  
-**A:** Travelmate tries n times (default 3) to connect, then the respective uplink SSID will be marked / renamed to '_SSID_\_err'. In this case use the builtin wireless station manager to update your wireless credentials.

In this case use the builtin wireless station manager to update your wireless credentials. To disable this functionality at all set the Connection Limit ('trm\_maxretry') to '0', which means unlimited retries.  
 
 **Q:** Is travelmate compatible with CC/Openwrt?  
 **A:** Travelmate was never tested with an ancient CC/OpenWrt release ... it should still work, but no promises.
