WAX 610 Slow, Rebooting Mitigates Issue

Hi again everyone, an update on the issue:

Good news, I haven't experienced the issue since downgrading and upgrading again.  Speeds have been solid.  Performing the same test as before (running Speed test from my phone, about 1.5m from the AP) I just got 545Mb/s down and 553Mb/s up.  That's great!

Some things to note:

my AP is configured to reboot itself twice a week (Sunday and Wednesday).  Previously I had it configured to reboot only once a week, then increased it to twice a week when I started experiencing the problems.  The scheduled reboots didn't seem to help.  I've left it set to reboot twice a week.

After downgrade and upgrade I also changed a few settings.

I enabled band steering on one of my wireless networks and left it disabled on another.  I tried testing both but after realised I may have made a mistake in my testing.

I also enabled rate limiting on my third wireless network, which is 2.4Ghz only for IoT devices.

I'll keep monitoring and report back if I notice anything interesting.
