Yes, but a number of us are now seeing this (where we hadn't before) and don't have the supposed culprits of wan status testing enabled... when we upgraded from .13 to .14, where .13 didn't show this problem and .14 does.
I think I found what's causing it (well, the high level cause though not a specific patch)... in that on the .13 firmware, the wanduck daemon is running, while on the .14 firmware it isn't at all, and that's why the link_internet nvram setting hasn't been updated.
I compiled the current .15 alpha and noticed that that firmware does get wanduck started up and running and so the problem is gone there as well, or at least I haven't seen it there.
Here's .14:
admin@RT-AC68U-77D8:/tmp/home/root# nvram show|grep link_internet
size: 56686 bytes (8850 left)
link_internet=0
admin@RT-AC68U-77D8:/tmp/home/root# ps -w|grep wanduck
3531 admin 4492 S grep wanduck
admin@RT-AC68U-77D8:/tmp/home/root#
And here's my personally compiled .15 alpha:
admin@RT-AC68U-77D8:/tmp/home/root# nvram show|grep link_internet
size: 56699 bytes (8837 left)
link_internet=2
admin@RT-AC68U-77D8:/tmp/home/root# ps -w|grep wanduck
237 admin 5096 S /sbin/wanduck
2471 admin 944 D grep wanduck
So it appears there's something in the .14 firmware (at least on the rt-ac68u with certain config?) where something is causing wanduck not to be started and this causes the internet status to be left showing "disconnected" when it's actually working fine.
