Losing WAN in 380.68_x in AC 3100

[Juan Robles]

I am experiencing a weird issue with all releases in 380.68_x, my ISP modem is configured as bridge and basically my router just makes a DHCP request and gets the IP and everything works.
With 380.66_X it just works, I barely have issues and my router is stable for weeks, with any releases of 380.68_x I always find out next day that the WAN link is down, the DHCP Renewal fails and bringing the interface down and up again fixes the issue.
Is anyone else experiencing a similar behavior? I'll just decide to stay in 380.66 but I am worried about KRACK and if the patch when released will be backported or not.

Did you see and read this post?
Especially the DHCP option being set to standard.

ok I just applied the settings change and I am going to wait for a day to see if the situation improves.
Thanks for the suggestion

Gave it a try but I am still experiencing the same issue, changing the settings to Normal mode didn't work.
