Question

Good Morning all,

In previous deployments of mine, abuse of a mobile internet connection has been an
issue. Not by mobile workers I might add! but by bored office colleagues when the
vehicle was stationary at company premises.

I appreciate that on the RUT955 I can fit a wifi client bridge to the ethernet WAN port
and use the health check function to detect the presence of an upstream router IP to
force WAN Selection (a pity this option cannot check for the presence of MAC address
too!) but what concerns me is that there are a LOT of public wifi hotspots around the UK
(e.g. BT Wifi, Virgin Media wifi , hotel wifi etc ) which are open & unencrypted but with
an upstream captive portal.

If the vehicle were to stop in range of one of these captive portals and the upstream private
IP was identical to that used at one of our depots, then my LTE WAN would be interrupted
which for continuity of service I would like to avoid.

I wondered therefore if there was a way to GPS "geofence" locations for WAN selection ?

Thinking like a programmer:

IF %GPSlocation <> (50.0**N, 1.0**E) OR
IF %GPSlocation <> (51.5**N,2.**W) OR
<<more IF / OR statements here>>
THEN
WAN = ethernet WAN
ELSE
WAN = LTE WAN
ENDIF

I also appreciate that careful selection of the upstream wifi bridge I can potentially
lock to a specific ESSID but budget for this programme is EXTREMELY tight at this
phase of the project and were probably going to be constrained to something like
one of those GL Series "Travel routers"  for the upstream WiFi WAN bridge as were hoping the
DC power from the RUT955 USB or a small USB hub will be sufficient to drive it .

If this isn't possible today , can I request it as a future feature please ? or can MAC address
also be added to the upstream health check for dynamic WAN selection please ?

Seasons greetings

Hi,

Unfortunately router do not have such feature.

But you could try to develop it by itself if you have programming skills. Router use RutOS which is based on OpenWrt. It support these languages: Busybox shell, Lua, C, C++.

GPL package you can find here:

Hi,

If you want to avoid programming, you can try to use this solution:

1. In Services -> GPS -> GPS geofencing create zones where you want to activate wifi WAN (https://wiki.teltonika.lt/view/RUT955_GPS#GPS_Geofencing);
2. Create two different profiles (system profiles): One with only LTE WAN enabled and other with LTE WAN and Wifi WAN enabled (https://wiki.teltonika.lt/view/RUT955_Profiles);
3. In Status -> Events Log -> Events Reporting create GPS rule, which will send SMS message with text <admin_password> pr <profile_name> when router enters or leaves zone. This will change from one profile to other (https://wiki.teltonika.lt/view/RUT955_Events_Log#Events_Reporting) (https://wiki.teltonika.lt/view/RUT955_SMS_Utilities#Change_profile).

Other wise you will need to create custom script, which will monitor GPS coordinates and accordingly select WAN source.

SUPERB idea Tomas! thank you so much!

Ive been tied up on another project since the new year but I will definitely give this a go

Its a pity that the event reporting cannot select a geofence by name  - i.e
ON ENTER "LondonOffice" or ON EXIT "ManchesterDepot"
(Teltonika  -  can this please be added in a future release ?)

But your suggestion will achieve my initial goal 100%
Many thanks again

Regards
