* usually the pre-configured travelmate setup works quite well and no manual config overrides are needed, all listed options apply to the 'global' section:
* trm\_enabled => main switch to enable/disable the travelmate service (bool/default: '0', disabled)
* trm\_debug => enable/disable debug logging (bool/default: '0', disabled)
* trm\_automatic => keep travelmate in an active state (bool/default: '1', enabled)
* trm\_captive => enable/disable the captive portal detection (bool/default: '1', enabled)
* trm\_minquality => minimum signal quality threshold as percent for conditional uplink (dis-) connections (int/default: '30')
* trm\_maxwait => how long (in seconds) should travelmate wait for a successful wlan interface reload action (int/default: '30')
* trm\_maxretry => how many times should travelmate try to connect to an uplink, '0' means unlimited retries. (int/default: '3')
* trm\_timeout => timeout in seconds for "automatic mode" (int/default: '60')
* trm\_minquality => minimum signal quality threshold as percent for conditional uplink (dis-) connections (int/default: '35', valid range: 20-80)
* trm\_maxwait => how long (in seconds) should travelmate wait for a successful wlan interface reload action (int/default: '30', valid range: 20-40)

* trm\_timeout => timeout in seconds for "automatic mode" (int/default: '60', valid range: 30-300)
* trm\_radio => limit travelmate to a dedicated radio, e.g. 'radio0' (default: not set, use all radios)
* trm\_iface => main uplink / procd trigger network interface (default: trm_wwan)
* trm\_triggerdelay => additional trigger delay in seconds before travelmate processing starts (int/default: '2')

**A:** In "trigger" 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**Q:** What happen with misconfigured uplinks, e.g. due to outdated wlan passwords?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. To disable this functionality at all set the Connection Limit ('trm\_maxretry') to '0', which means unlimited retries.
