To clarify, the white premium discs run firmware SGAB208326 and the dark grey wi-fi 6 ones run SGAC208326, I run both. I believe this thread relates to the release of both firmwares as per the thread subject title. They appear to be highly related versions of the same although for different hardware.
I had issues a couple of firmware releases back when plugging all discs in via Ethernet, the BT helpline suggested removing the hard wiring and allowing the discs to do their backhaul over Wi-Fi, which did indeed resolve the issues. I’ve not re-tried tried Ethernet since, and to be honest the speed performance over Wi-Fi backhaul is superb anyhow. Over the first few hours and days the discs will adjust to the most efficient topology.
I appreciate that hardwiring may be necessary to get through thick sandstone walls for example, but going Wi-Fi is worth a try if it suits your location. Hope this helps.
