* STA interfaces operating in an "always off" mode, to make sure that the AP is always accessible
* easy setup within normal OpenWrt/LEDE environment
* fast uplink connections
+* support multiple radios
* procd init system support
* procd based hotplug support, the travelmate start will be triggered by interface triggers
* status & debug logging to syslog
## OpenWrt / LEDE trunk Installation & Usage
* download the package [here](https://downloads.lede-project.org/snapshots/packages/x86_64/packages)
* install 'travelmate' (_opkg install travelmate_)
-* configure your network to support (multiple) wlan uplinks and set travelmate config options (details see below)
+* configure your network to support (multiple) wlan uplinks and set travelmate config options (see below)
* set 'trm\_enabled' option in travelmate config to '1'
* travelmate starts automatically during boot and will be triggered by procd interface triggers
* trm\_maxwait => how long (in seconds) should travelmate wait for wlan interface reload action (default: '20')
* trm\_maxretry => how many times should travelmate try to find an uplink after a trigger event (default: '3')
* trm\_iw => set this option to '0' to use iwinfo for wlan scanning (default: '1', use iw)
+ * trm\_radio => limit travelmate to a dedicated radio, e.g. 'radio0' (default: not set, use all radios)
* trm\_iface => restrict the procd interface trigger to a (list of) certain wan interface(s) or disable it at all (default: not set, disabled)
