ROUTING FAILS between 2.4Ghz and 5Ghz networks after a few days. RT-AX86U Pro

This router CONSTANTLY stops routing traffic between the two wireless networks. Only a reboot or turning off/on one of the radios causing the routing to start up again. Using latest firmware.

 Hard reset then reconfigure from scratch

Hi @Freddypop ,

Thank you for contacting us. To better assist you in resolving the issue, we would like to gather some additional information:

  1. Channel settings: Have you tried manually setting the 2.4GHz and 5GHz channels on your wireless router? It's recommended to choose less crowded channels to reduce interference from other wireless devices.
  2. DFS channels: Does your wireless router support DFS (Dynamic Frequency Selection) channels? DFS channels can automatically select less congested channels, but there may be restrictions in some regions. We suggest you try enabling or disabling DFS channels to see if it improves the issue.
  3. Environmental interference: In addition to wireless routers, Bluetooth devices, cordless phones, microwaves, and other appliances can also use the 2.4GHz band. These devices may interfere with the wireless signal. We recommend checking if there are any other devices around the router that could cause interference and try to move them away from the router.

Check your IP/Subnet/Default gateway setting from DHCP for the two networks and respective clients to determine how different or if overlapping, etc.
