AX3000 Drops WAN

[Rob R]

I have an occasional issue with my otherwise great RT-AX3000. It will decide that Internet is disconnected when my AT&T Gb gateway (Arris BGW210-700) shows as up. My fix has been a reboot to the AX3000, which fixes all. (I'm open to other suggestions.) Logs did show only one WAN_Connection error: "ISP's DHCP did not function properly". Any thoughts?

Here is a thread on that with links to other similar posts and some solutions - one at the very end may work.

My gateway's DHCP lease is 10 minutes. When the WAN link fails, it remains down indefinitely until I reboot. I provided that error because it's the only one I saw related to WAN and occurring around the time of the WAN failure. Anyhow, it's a rare failure, so I'll hold off on command line tweaks unless it happens again.

Thanks for the reference.

I fixed mine creating a special route table for the arris So my IPTV wont make me lose WAN.

There's also a known issue with DHCP renewals from the ISP router when using Adaptive QoS - if you use it try disabling QoS, if this fixes it there is a workaround and detailed information describing the diagnosis on the Wiki https://github.com/RMerl/asuswrt-merlin.ng/wiki/Adaptive-QoS-Optimization
