Hi

I have a simple AIMesh network with an RT-AX88U as my main router and an RT-AC86U as the only AIMesh node. I was a bit disappointed to find that Guest networks were not supported using AIMesh, and then happy to find out that this functionality had been added with a firmware update.

I upgraded the firmware on the main router to 3.0.0.4.386_42820-gae9dd15 and the node to 3.0.0.4.386_42820-gae9dd15. These are as far as I know the latest versions.

I set up my guest network as described here https://www.asus.com/support/FAQ/1045327/

The guest network works fine providing I am in range of the main router, It gets an IP address on a different subnet. My main network is 192.168.1.XX. Connecting to the 2.4GHz Guest network assigns an IP address on 192.168.101.XX, and the 5GHz Guest network gets an IP address on 192.168.102.XX.

The problem is this only works if in range of the main RT-AX88U router, If I am range of the RT-AC86U node, it fails to assign an IP address.

Can anyone make any suggestions as to what the issue might be.

Cheers

Did you try resetting all firmware and configuring from scratch? Some firmware updates need this reset, so that would be the next thing to try.

Do you have sync to nodes enabled in guest 1?
Use only WPA2 in the AX WIFI.

This is how I have them set.

I don't want to do that unless I really have to. I assume that would set everything back to default settings?

A reset will set everything back to the defaults values that are defined in the new firmware, not the old firmware. Without the reset, you are using the default values of the old firmware... but running on the new firmware. Hence the potential for glitches.

Would it work if I saved my current settings, then did a reset and then restored the settings. Or would that just potentially reintroduce my current issue? I have all my DHCP reservations as I want them and would be a pain to have to manually do them all again. Cheers

Save your configuration first. Reset the routers, do manual configuration with automatic DHCP, test if AiMesh guest network issue is gone. If it is - add your DHCP reservations manually, don't restore anything. If it isn't - restore your configuration files and wait for Asus to fix the issue. In my experiments with AiMesh I found mixing routers in AiMesh may result in unexpected behavior.

Thanks for the links OE. It is something I will try but will have to wait until I am a little less busy. Can I just ask if this is a known issue, that has been known to be fixed by doing a reset?
Thanks for everyone's assistance

Asus introduced guest networks on nodes recently. It is possible that there is an issue, but I don't recall a specific report of a confirmed issue on any particular models/firmware.

Since you updated firmware with significant revision, it is most likely that you need to just finish commissioning your network, starting with a firmware reset, to eliminate the likely culprit. This is the recommended next troubleshooting step.

And ask yourself, do I really need all of those DHCP reservations... do I really need them so bad that I will maintain them for the rest of my life? If not, then let the DHCP server manage most of them for you.

Get on with it or live with it, imo. :)
