Hello @Aaron_Brooker.
There was an issue for some of a very early batch of the Balance One routers with a “RAM Timing Process”, you can see the official announcement here and notes on the fix.
Since then, we have deployed countless numbers of these, and they have kept on working and have firmware 8.1.1 or later on them.
Follow with a support ticket if you are still having issues as recommended by @MartinLangmaid above.
Happy to Help,
Marcus
