Is there a way to downgrade the Flint 2 firmware to a version prior to 4.7.0? The 4.7.0 update has been completely unusable for me.
Without hardware acceleration, my connection speeds drop to 100 Mbps on WAN1 and 30 Mbps on WAN2. Previously, I was able to get full speeds for both of my ISPs: 100 Mbps on WAN1 and 200 Mbps on WAN2.
When I enable hardware acceleration, the speed returns to normal. However, WAN2 constantly disconnects, forcing me to rely on a single WAN port.
Just install an older firmware found here: GL.iNet download center
But please keep in mind you should not keep your settings, so a reset is mostly required.
But before, try also the 4.7.0-op24

I had to not only install a previous firmware version but also reset the router to factory settings to get it working properly again. After that, I was able to upgrade to version 4.7.0 without any issues. Please ensure more thorough testing before releasing new firmware updates
It highly depends from which firmware you are coming and what you changed.
Reseting the device is a usual troubleshoot step and mostly successful.
