RT-AC68P & FiOS: WAN dropouts on 386.x

[MamaLing]

The vlan 56-62 entries make no sense. They’re bridging LAN directly to WAN in like 3 places.

factory reset time. Do not restore a backup.

Hey! I restored to the router factory defaults, additionally, I went back to 384.19 firmware, then I had to restore factory defaults again, because of the password wasn't working for the admin account. Something is still going on, on my iPhone I can't make the Wireguard VPN to work. The phone connects to the VPN, but the internet is dropping frequently. So at this point I'm out of my plans.

This is what I get back when I ssh to the router.

That I do not know. It’s possible the VLAN 501/502 is used to backhaul guest traffic over the mesh. If you use aimesh, you might want to modify the script to leave the VLANs on the bridge but take the WAN port off:

robocfg vlan 501 ports “1t 2t 3t 4t 5t”
robocfg vlan 502 ports “1t 2t 3t 4t 5t”

And remove the brctl lines. I do not know if this will work as I have no way to test it.

edit to add, only do this on the router connected to the WAN. You want to leave the vlans on the WAN port for the mesh nodes, especially if you use Ethernet backhaul. I think the bug in ASUS’s code is they add the WAN port in router mode. It should only be added in AP mode.

@CoyoteDen I followed your work, and tested it on 2 of my RT-AC5300 (meshed). It solved the Guest Network 1 issue with this:

robocfg vlan 501 ports "1t 2t 3t 4t 7t 8t"

Removed "0t" from the 501 vlan.

@ASUSWRT_2020 and @RMerlin Hope you folks are watching and will consider making adjustments to the firmware. Kudos to @CoyoteDen!

Thanks

Reproduce it on stock firmware, then report it to Asus using their Feedback form if it still occurs on the latest stock firmware. I don't touch that code because I don't understand any of it.

Sure, will do it via my AC68.
