C6300 2.4GHz wifi radio stops working and requires reboot

I have a new c6300 that I bought and installed a few weeks back with firmware V2.01.14 and configured to only operate the 2.4GHz wifi radio, i.e. I have the 5.0GHz wifi radio unchecked/disabled in advanced | advanced setup | wireless settings because i only need/use the 2.4GHz wifi radio.

What im finding is that every week or so, seemingly after making use of wifi network by my mobile devices to carry out mobile OS updates, that the 2.4GHz wifi radio stops working.

By that i mean the SSID no longer shows up in available wifi networks on my laptops, tablets and phones and for those that are already configured with that wifi network ssid & password they are unable to connect.

The only resolution Ive been able to arrive at is to visit the c6300s administration web UI advanced view and select the "reboot" option after which the 2.4GHz wifi radio starts showing up and working again for all my devices configured to use it.

Does this sound like something others have also experienced b4 that has a known fix or a firmware update that addresses it?

Thanks, Robert.
