I have the RUT955 and ever since I updated it to the latest firmware RUT9XX_R_00.06.04.3 I get the following error when trying to access the mobile data config page:

/usr/lib/lua/luci/dispatcher.lua:217: Failed to execute function dispatcher target for entry '/admin/network/mobile'.

The called action terminated with an exception:

/usr/lib/lua/luci/dispatcher.lua:217: Failed to execute cbi dispatcher target for entry '/admin/network/mobile/general'.

The called action terminated with an exception:

...b/lua/luci/model/cbi/admin_network/ifaces_mobile.lua:1: attempt to concatenate a nil value

stack traceback:

[C]: in function 'assert'

/usr/lib/lua/luci/dispatcher.lua:217: in function 'dispatch'

/usr/lib/lua/luci/dispatcher.lua:93: in function </usr/lib/lua/luci/dispatcher.lua:93>

This has rendered the device useless as I cannot configure any SIM settings in order to get a mobile data connection.

I've tried re-applying the firmware without keeping configuration settings and downgrading to earlier firmware versions, nothing appears to fix this issue. Please advise.

Right now latest firmware is RUT9XX_R_00.06.04.5, could you try upgrading and check if issues are fixed?

Sorry, yes - I have already tried this - the firmware is currently on 04.3 from my downgrade - the issue began when I flashed 04.5 and is now present regardless of firmware version.
Have you tried opening routers WebUI in private (incognito) browser window? This will ignore all cached information from router.
Thanks for the update, I've just tried this but the same issue persists.
Please generate troubleshoot file and send it to me via Private message.

Also, could you try reflashing firmware via bootloader? You can find more information here:


Did this get resolved having same issue?
