## Main Benefits and Features
-* Easy setup from LuCI web interface
- with **Interface Wizard** and **Wireless Station manager**
-* Display a QR code to
- transfer the wireless credentials to your mobile devices

* Fast uplink connections
* Supports routers with multiple radios in any order
-* Supports all kinds of uplinks, including hidden and enterprise uplinks.
- (WEP-based uplinks are no longer supported)
-* Continuously checks the existing uplink quality,
- e.g. for conditional uplink (dis)connections
+* Supports all kinds of uplinks, including hidden and enterprise uplinks (WEP-based uplinks are no longer supported).
+* Continuously checks the existing uplink quality, e.g. for conditional uplink (dis)connections
* Automatically add open uplinks to your wireless config, e.g. hotel captive portals
-* Captive portal detection with a
- 'heartbeat' function to keep the uplink connection up and running
-* Captive portal hook for auto-login configured via uci/LuCI.
- Use an external script for
- captive portal auto-logins (see example below)
-* VPN hook supports 'wireguard' or 'openvpn' client
- setups to handle VPN (re)connections automatically
-* Email hook via 'msmtp' sends notification e-mails
- after every successful uplink connect
-* Proactively scan and switch to a higher priority uplink,
- replacing an existing connection

* Connection tracking logs start and end date of an uplink connection
+* Check router subnet vs. uplink subnet, to show conflicts with router LAN network
* Automatically disable the uplink after n minutes, e.g. for timed connections
* Automatically (re)enable the uplink after n minutes, e.g. after failed login attempts
* (Optional) Generate a random unicast MAC address for each uplink connection
| trm_enabled | 0, disabled | set to 1 to enable the travelmate service (this will be done by the Interface Wizard as well!) |
| trm_debug | 0, disabled | set to 1 to get the full debug output (logread -e "trm-") |
| trm_iface | -, not set | uplink- and procd trigger network interface, configured by the 'Interface Wizard' |
+| trm_laniface | -, lan | logical LAN network interface, default is 'lan' |
| trm_radio | -, not set | restrict travelmate to a single radio or change the overall scanning order ('radio1 radio0') |
| trm_scanmode | -, active | send active probe requests or passively listen for beacon frames with 'passive' |
| trm_captive | 1, enabled | check the internet availability and handle captive portal redirections |
| trm_netcheck | 0, disabled | treat missing internet availability as an error |
-| trm_proactive | 1, enabled | proactively scan and switch to a higher prioritized uplink, despite of an already existing connection |
+| trm_proactive | 0, disabled | proactively scan and switch to a higher prioritized uplink, despite of an already existing connection |
| trm_autoadd | 0, disabled | automatically add open uplinks like hotel captive portals to your wireless config |
| trm_randomize | 0, disabled | generate a random unicast MAC address for each uplink connection |
| trm_triggerdelay | 2 | additional trigger delay in seconds before travelmate processing begins |
| trm_maxwait | 30 | how long should travelmate wait for a successful wlan uplink connection |
| trm_timeout | 60 | overall retry timeout in seconds |
| trm_maxautoadd | 5 | limit the max. number of automatically added open uplinks. To disable this limitation set it to '0' |
-| trm_captiveurl | http://detectportal.firefox.com | pre-configured provider URLs that will be used for connectivity- and captive portal checks |
+| trm_captiveurl | http://detectportal.firefox.com | custom/pre-configured provider URLs that will be used for connectivity- and captive portal checks |
| trm_useragent | Mozilla/5.0 ... | pre-configured user agents that will be used for connectivity- and captive portal checks |
| trm_nice | 0, normal priority | change the priority of the travelmate background processing |
