I got the new hub 4 yesterday, while the WIFI seems stable compared with the Hub 3 I have been unable to get some of my smart light switches connected. With the Hub 3 I just disabled 5ghz to set them up and then re-enabled 5Ghz. They cant even connect to the Hub 4, tried everything. Ended up having to use an old Edimax Access Point/Bridge/Extender device to provide a viable 2.4Ghz network for them, wasting one of the 1gbit ports on the Hub 4 in the process. Annoyingly I was using that Edimax for a wired only device, asked VM to either send an engineer to "attempt" to resolve or pay me the £20 for the replacement wifi/ethernet bridge.. zero help. I only got the 1Gbit for the Hub4 as it was £1.50 a month more than I was paying and £40 for the unit. If you have SONOFF wifi switches I would avoid.
