Wifi dongle won't associate and broadcast as AP

Installing and Using OpenWrt Network and Wireless Configuration
1

Hi everyone,

I'm hoping you can help me solve an issue I'm having with upgrading my OpenWRT raspberry pi to 18.06.

When I upgraded my Rpi to 18.06 and imported the configuration it broke the wireless connectivity. The dongle is still able to detect wifi networks and connect in client mode, but can't operate in AP mode. I've since re-inserted the backup Chaos Calmer SD card back into the RPi and it functions as normal. I've been trying to troubleshoot with an identical dongle in another RPi and haven't been able to get very far. Every time I try to start the wifi AP in Luci it just says "Wireless is not associated".

The system log when I try to start the wifi dongle in AP mode is as follows:

Are you certain that the dongle you're using is capable of AP mode?

Yes - as stated it did so on Chaos Calmer and I'm using an identical dongle on another RPi in AP mode.
