TUF-AX3000 V2 and AIMesh wireless backhaul not working

[ajlapina]

So I have a TUF-AX3000 V2 as my main router, along with 3x XD5 and a RP-AX58 range extender, all working as access points with AIMesh. The XD5 all use ethernet backhaul, while the RP-AX58 is wireless on 5ghz. I have had no issues with any of the nodes or coverage in this setup, until I updated firmware on all devices a couple of days ago. Current firmware levels:
TUF-AX3000 V2 = 3.0.0.4.388_23859
XD5 = 3.0.0.4.388_24021
RP-AX58 = 3.0.0.4.388_24694

After firmware updates, the XD5 all functioned fine (ethernet backhaul), but the RP-AX58 dropped out of the AIMesh and would not reconnect. I factory reset it countless times and tried to re-add back to my AIMesh. The only way I could get it to connect is if it was placed within about 3 feet of my main TUF-AX3000 router, and it would only connect via 2.4ghz showing a weak signal. As soon I move it back to its origional location, it would fail to connect and never connect to any of the XD5. I was pretty convinced the RP-AX58 firmware broke it. The main TUF-AX3000 V2 has strong wifi signal, as numerous devices around the house are currently connected directly with both 5ghz and 2.4ghz. Today I plugged in the RD-AX58 with ethernet to my router, joined it to the AIMesh, and it worked fine. When removing the ethernet, it will not failover to wireless backhaul at all. I then unplugged the ethernet backhaul from a couple of my XD5, and they would not join AIMesh via wireless. I'm starting to think the issue is with the main TUF-AX3000 V2, and wireless connection to AIMesh nodes no longer working. All AIMesh nodes are only functioning and visibile when connected with ethernet. They are all set to Auto for the backhaul connection priority, and the main router has Ethernet Backhaul Mode disabled. Any suggestions on what I can do next? Is it possible to rollback firmware to the previous version? It seems like 3.0.0.4.388_23859 may have broken wireless AIMesh backhaul?

Yes you should be able to manually install an older firmware version.  If you roll back one model's firmware and find it corrects the problem you've definitely found fault in the latest firmware.

Hi @ajlapina ,

Thank you for your inquiry. 

Regarding the connection issues you are experiencing with your AIMesh network nodes, we recommend that you try the following steps for troubleshooting:

1. Restore factory settings: Please restore all your AIMesh nodes, including the TUF-AX3000 V2, XD5, and RP-AX58, to their factory default settings.
2. Step-by-step configuration and testing:
   First, configure the TUF-AX3000 V2 as the main router and ensure it is operating correctly.
   Next, add the XD5 nodes one by one, and confirm that each node can connect to the AIMesh network normally via Ethernet backhaul.
   Then, place the RP-AX58 close to the main router and attempt to add it to the AIMesh network wirelessly. Once the connection is successful and stable, gradually move it to its intended location and check the connection stability.
3. Check wireless channel settings: Please check the wireless channel settings of your main router to ensure that the 5GHz band is not being occupied by other devices or interference sources. You can try manually setting a channel with less interference.

If the problem persists after trying the above steps, please use the problem reporting function built into your router's system to submit relevant logs for our further analysis.

Please follow the steps below to report the issue, and we will assist you:

1. Connect your device (PC, laptop, etc.) to the router, then open the Web management interface (http://router.asus.com/) and log in to your router.
2. Click on "System Administration" and select "Problem Report."
3. Fill in your region, email address (required), ASUS service/case number, issue type, and a description of the issue.
4. Please read and agree to the privacy policy and relevant service terms.
5. Click "Send" to submit your form.

Additionally, please send us the following information via private message: product serial number, the time the problem report was submitted, the email used for the problem report, the time the issue occurred, the MAC address of your device, and a network architecture diagram of your current environment.
