Hello. I bought this router (Archer C6 US) back in March 2020 and since then I've been facing this issue where devices connected to the 2.4 Ghz wifi would loose connection while 5 Ghz wifi faces no issues at all. When this happens, the SSID of 2.4 Ghz wifi is visible on client devices but the devices are unable to connect to it. All devices are relatively new and include cellphones and laptops. Connection is lost on all devices at the same time. This happens multiple times a day.
I have already tried resetting the router, reinstalling the firmware and downgrading the firmware to an older version but nothing seems to fix the issue. I have also tried the things mentioned here:
A temporary fix is to either restart the router or just restart the wifi (on the router). Are you guys planning to release a new firmware to fix this issue like you have done for the EU version of the same router model? Is there a beta driver available for testing?
