Yea I'm not sure why your router has that issue, I've searched and searched and don't see it and I have no other reports of it.

 

[Ranger802004]

Published some minor clean up of syntax and adjustments regarding WAN0IFNAME and WAN1IFNAME variables and published as beta6.

 

[Stephen Harrington]

and published as beta6.

Just whilst I was trying to check if I had latest beta 5, spun me out ...

Update from V2.0.0-beta5 to V2.0.0-beta6, appears to be working, different line error in the last part of the script:

[Ranger802004]

Minor addition to v2.0.0-beta6 that will create an additional IP Route in each WAN specific routing table for the Target IPs accordingly, this is in addition to the script already creating default routes in each of these tables.

Yep I got that too - seemed to fix itself after I forced another update?

That is because I changed the code so it was failing checksum with the available code on the repo ( don’t match).

Hello @Ranger802004
I tested your last script on AC86U and AC68U with firmware 386.9 and didn't work.
Someone tried the script on the same models as me ?

I'm searching buying AX88U

 

[Weston]

Let me check.

If you’re having lock ups try turning on Check NVRAM.

Works like a charm on my AC86U from inception. Just minor bugs that @Ranger802004 took care of relatively quickly. Note I use mine configured in HA mode active/passive, not load balancing active/active.

I am considering forcing AC86U to have NVRAM checks on since it is highly prone to the stuck commands issue.

@Ranger802004 , how to do that ?

It's an option in the configuration menu.

I just got my new AX86U delivered today and tried the beta 6 of this script. The failover to 2nd WAN is working, but recovery back to primary WAN doesn’t work automatically. I have to do the switch back manually. And the log capture showing strange error “WAN Failover is currently disabled”. Where the status shows it is enabled

Attached is the log and the script status when it was on 2nd WAN.

Is there anything wrong? The only other 2 script I have are FlexQOS and Adguard Home

This seems similar with my case when the WAN0 got 100% packet loss after it got down and the ping stopped working. @Ranger802004


@wolvenstein when this happens. Restarting Wan-Failover using the option should make the WAN0 ping work again and it should move it back to WAN0. Also what happened with the internet? Did you try it on purpose? Or was it actually down? Did you unplug the wan connection for the WAN0? Or did you just make the internet stop without the WAN port actually getting unplugged? (Let's say you unplugged the coax of the modem. The modem itself is still on and connected to the router but the internet just goes down)

For testing purpose, I switch off one of my internet modem to see if the router will failover to my 2nd internet. And then switch on that modem again, but the router unable to switch back to it.

And yes, I noticed restarting the script do the trick. It will switch back to the primary internet connection

Yeah. Does it fail to fallback if you keep the modem turned on and connected. But you cut the internet off by for example unplugging the coaxial cable?
