Important update! 4th channel/frequency, in case you may need it
But most importantly, the random disconnects are fixed. And i thought i did something wrong.
Very happy with this update, good job!
Update:
After a night of sleep, 7 link downs. Testing in the living room.
Now off to work, see how it goes.
Update 2:
After about 10 hours, no more link downs. Who knows, maybe my living room is haunted during the night.
Will keep testing!
Update 3:
Link downs from 8 to 23 during day time.
So yeah, the fix is not 100% yet.
Hope the developers read this.
