All four units are XT8 v1 and if I've read the previous posts correct, I should have selected 5GHz-2 channel for backhaul, which I don't remember having done. Is that a setting I can adjust now or should I reset the router and do a re-installation (I don't mind)?
I've had stable operation with decent performance for all wireless and wired devices for 64 days now, which is a personal record for this gear. I spent over a year trying various combinations of firmware (stock and Gnuton) and settings.
Happy to share my settings. To avoid writing a book or loading lots of screen shots, I've only included the settings that I think are pertinent to stable operation (or that might raise questions). If you want screen shots, I can send you those too. The key things of interest are that I set the XT8's to auto-reboot every morning at 3:00am and have hard set the wireless backhaul bandwidth to 80 MHz.
My home setup is an XT8 v.1 primary mesh node connected to a Ziply Fiber symetrical 1 Gbps up/down Internet connection. The primary is connected using wireless backhaul to two XT8 v.1 secondary mesh nodes, one about 30 feet away from the primary and one about 40 feet away from the primary. Wireless backhaul only. All three XT8's running 3.0.0.4.388_23285
