Last night, the 2.4GHz band on my XR500 router suddenly stopped showing up, while the 5.0GHz band continues to work fine. I attempted to resolve the issue by rebooting the router through the interface, disabling and reenabling both the 2.4GHz and 5.0GHz connections, and changing the channel to a less congested one. Despite the router's indicator showing the 2.4GHz light as blue, the system information tab indicates it as disabled.
I'm not using smart connect since I specifically need the 2.4GHz band for certain devices at home. I've been running on XR500 V2.3.2.134-dumaos33-rc14 for a few months without encountering any issues until yesterday. Any suggestions on what I can do to resolve this?
