I have a RUT240 router which suddenly stopped working. Can't connect to mobile network.

The problem is that in setup wizard second step (2. Mobile) is not accesible and it gives following status:

"/usr/lib/lua/luci/dispatcher.lua:532: Failed to execute cbi dispatcher target for entry '/admin/system/wizard/step-mobile'.

The called action terminated with an exception:
...usr/lib/lua/luci/model/cbi/cfgwzd-module/step_3g.lua:8: attempt to concatenate a nil value
stack traceback:
	[C]: in function 'assert'
	/usr/lib/lua/luci/dispatcher.lua:532: in function 'dispatch'
	/usr/lib/lua/luci/dispatcher.lua:272: in function </usr/lib/lua/luci/dispatcher.lua:271>"
Under  Network -> Mobile there is an error: "Modem not detected" at top of page.

I tried rebooting, factory reset, updating firmware via bootloader to version RUT2XX_R_00.01.14.5.

But still have the same problem.

Can somebody help me with this error?

Best regards

Thanks for contacting TELTONIKA | Crowd-support forum.

It is recommended that you upgrade the router's Firmware whenever there is a new version.

Please try to upgrade your router’s firmware to latest one RUT2_R_00.07.01.2, without keep setting.

Firmware can be upgraded either from server or from an image uploaded from your computer.
