ASUS ZenWiFi AX Whole Home Tri-Band Mesh WiFi 6 System Not sure if this is the right place to ask…. I am thinking of upgrading my Google Mesh wifi to the above. Has anyone used this and does it...

Great news, hopefully a bug with AiCloud ASUS can resolve going forward.

Manually updated to 3.0.0.4.388_24709 this evening, and all good so far.

At the end of a long day, I had to read the release notes a few times to fully grasp that they added AES as an option to WPA (WPA/WPA2). With WPA2 now 20+ years old, I’m honestly surprised that Asus still supports WPA at all.

I’ve been using WPA2/WPA3 AES on 2.4 & 5G-1 for years and have never had any connection issues with Google/Nest, Kasa, or Phillips IoT devices.

5G-2 backhaul is set to WPA3 AES

Well spotted and yes WPA2 has been around for a while now, does seems as though Wireless speeds increase exponentially, but less so the Encryption side I assume for the sake of backward compatibility.

I still remember WEP (Wired Equivalent Privacy) back in the day and the jump to WPA was a big step (improvement) back in those days.

I have “fallen” on an interesting issue related to static routes.  The same issue occurs both in stock XT8 software and 3004.388.8_4-gnuton1.

What I am trying to do is add a static route to a router connected to VLAN 503 on Guest Network 1.

If I add a static route using the web gui to an IP address on the “Non Guest” part of the router (say 192.168.48.4) then every thing works normally. A route is created in the gui and a matching entry created in the route table.  If however I point a static route at a device in the guest 1 network (in this case 192.168.103.250) the route appears to be created in the gui (see attached) however looking at route -n no route is actually created and a bunch of the following error is generated.

Jun 2 06:54:07 kernel: ^[[0;33;41m[ERROR mcast] bcm_mcast_netlink_process_snoop_cfg,1015: interface 24 could not be found^[[0m
Jun 2 06:54:07 kernel: ^[[0;33;41m[ERROR mcast] bcm_mcast_netlink_process_snoop_cfg,1015: interface 24 could not be found^[[0m
Jun 2 06:54:07 kernel: ^[[0;33;41m[ERROR mcast] bcm_mcast_netlink_process_snoop_cfg,1015: interface 24 could not be found^[[0m

If however, I delete the static route from the gui and add it via ssh with:

ip route add 192.168.20.0/24 via 192.168.103.250

The route is created correctly and everything works correctly.  As expected the web gui is “unaware” of this route (even though it works just fine).

Here is a snippet from the route table (route -n) (note the 81.0 subnet is created by OpenVPN):

192.168.20.0    192.168.103.250 255.255.255.0   UG    0      0        0 br3
192.168.48.0    0.0.0.0         255.255.252.0   U     0      0        0 br0
192.168.81.0    0.0.0.0         255.255.255.0   U     0      0        0 tun21
192.168.102.0   0.0.0.0         255.255.255.0   U     0      0        0 br2
192.168.103.0   0.0.0.0         255.255.255.0   U     0      0        0 br3

It appears that the gui is getting “confused” when it tries to create the route however the rest of the system is “happy”.

Any thoughts appreciated.

Welcome to the world of GUI vs CLI (CLI always wins out)

It’s a common problem across various router models and firmware platforms where you add a valid static route via the web GUI

• But the router firmware fails to commit the route because the VLAN interface is misunderstood, not fully accessible, or treated specially (e.g., as isolated/guest).

• The underlying Linux system is totally capable of handling the route, it’s just the GUI that is not working as it should.

I used to have this issue all the time when I was working with Cisco kit back in the day.

I cannot tell, does the route remain persistent when you enter via CLI ? (after reboot)

No it does not, the “custom” static ip route entry is lost on reboot or if the static route table is changed via the GUI.

I added the ip route add command from my post above to services-start and that works just fine (though this does not cover all potential failure cases based on what I’ve read). 

The services-start addition gives me a workable solution using Merlin/Gnuton but I’m not aware of one for stock software.

Any chance you can pass this “upstairs” to ASUS to see if they have any interest in fixing it?

BTW as someone who also worked on Cisco stuff back in the mists of time, “Cisco had a GUI?”

The Cisco GUI had its challenges also, back in the day

Can I ask you to send a feedback, then if you use the same email address as you have used when you registered with this forum, ASUS can locate your feedback easier and I can chase them if needed ?

Feel free to mention you have spoken with ‘UK Sentinel’ in the feedback message as this will hopefully help encourage investigation.

I will certainly do a feedback. What is the correct link to use?

I’ve submitted the feedback via the GUI.  No idea if it actually made it since the XT8 crashed about 20 secs after submitting the Feedback.  I did use the same email address as I use here.

This is what I got in the logs:

Bad luck, it looks like your Feedback was sent or at least started to send and then a QoS (Port Shaper) issue happened which caused the crash, the Routers Internal clock then resets to default while it sorts itself out (Dec 31).

If you do not hear from ASUS in say a week or two, try running the static routes using the web gui again and then send another feedback.

I tried it again this morning and this time the feedback appears to have submitted successfully.
