When I click "EDIT" on the marked WAN link I get this message:
/usr/lib/lua/luci/dispatcher.lua:217: Failed to execute cbi dispatcher target for entry '/admin/network/wan/edit/wwan0v6'.
The called action terminated with an exception:
...usr/lib/lua/luci/model/cbi/admin_network/wanEdit.lua:8: attempt to index local 'h' (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>
I guess that this has something to do with IPv6 enabled on WAN and it is trying to get IP from my ISP but fails. But I hope that this can help in any way to get IPv6 on WAN (both wired and mobile) as soon as possible.
By the way, I am running: FW ver.: RUT9XX_R_00.06.06.1
