Network issues with ASUS AiMesh, signal loss on RT-AX88U and RT-AX92U models.
Network issues with ASUS AiMesh, signal loss on RT-AX88U and RT-AX92U models.
In summary, over the past year I've been clashing with Spectrum about frequent internet interruptions. After a supervisor finally addressed the matter, I dug deeper into my internal network and noticed inconsistent connectivity—both Wi-Fi and Ethernet. My setup included an ASUS RT-AC1900P router, two RT-AX92U mesh nodes linked via Ethernet, and a 10-port gigabit switch connecting them. The problem seemed to stem from the mesh system or possibly a faulty node. I replaced my main router with an RT-AX88U, which initially worked for 12 hours before issues returned when adding a node. After turning it off, stable connections lasted another 24 hours. This suggests the issue might relate to the AIMESH system or network configuration. I've attached a basic network diagram and router settings to help troubleshoot. I prefer a single SSID for easier integration with Google Home, so I switched from three separate SSIDs across different routers. The network runs on 2.4GHz (5GHz radio off), which may be contributing to the instability. This isn’t a confirmed known problem, but it’s definitely solvable with adjustments. Thanks for your support!
@eddie200112 Hopefully, you've seen the AiMesh setup process done before. If not, here's a good guide. Wanted a few clarifications: 1. Is the 'Netgear Modem' just a modem, or is it a gateway device? 2. Are the AiMesh nodes connected to the switch via their respective WAN ethernet ports? 3. If you bypass the switch and run individual ethernet uplinks from the AiMesh nodes directly to the primary Asus router, do you still experience the problem? I understand an intervening unmanaged switch is not supposed to affect wired backhaul from working properly but, according to your explanation of the issue, introduction of this particular switch in this configuration seems to create the problem.
Yes the modem functions as a standard modem.
Yes they are linked to the WAN ports on each node.
Yes I've attempted to run the ethernet backhaul directly to the main router for both nodes, but the same problem continues. I also upgraded to an ASUS AX88U and set it as the primary router, yet the issue remains. I swapped one of the AX92U nodes with the old Asus router in AIMesh mode, and when connected it still fails. I believe this points to a bug within the Aimesh framework. I'm unsure what else to try at this stage.
