A bit of a strange issue here. I have BT Whole Home WiFi (white discs) installed with all 4 discs using Gbit ethernet backhaul (with one via homeplug adapter). The master disc is plugged into the (non-BT) router and serves the TV, Apple TV, etc. over 5GHz WiFi. These devices are all within 1m of the master disc.
After a period of between one to six weeks, the master disc stops accepting 5GHz clients. All the 3 other discs still are happy to access 2.4 & 5 GHz clients but the master disc stubbornly only accepts 2.4GHz. The consequence of this is that the TV, etc. either connects to a (remote) disc over 5GHz or falls back to 2.4GHz. This make the streaming experience (NetFlix, etc.) much slower.
I have:
- factory reset all discs
- switched the physical master disc with one of the others
with no effect. If I then do a soft restart via the App, all is well for next few weeks.
Looking at the log for the master disc, I can see the transition from a mixture of "IF[5G]:STA" and "IF[2.4G]:STA" records as new clients come and go, to a period where all you see is the 2.4GHz only client records e.g. "IF[2.4G]:STA". For the current period, this regression happened after 3 weeks.
I am puzzled 😞
