Some devices not connecting to Hub 4
Recently one of the devices I have connected to wifi dropped out and would not let me reconnect it to wifi. It's a datalogger for my PV inverter and had worked fine since it was installed 3 months ago. While investigating I found that my phone wouldn't connect to the 2.4GHz wifi that the datalogger and many other devices are on although it's fine on the 5Ghz band (I have both running with different names). Then when trying to resolve that I found that the phone would connect to 2.4 wifi if I set it to use phone MAC instead of random MAC. Anyway this option isn't available to me for the datalogger but I'm thinking this might not be connecting for the same reason. And then when I was talking to the datalogger tech support guy he said he was with VM and had heard of hub DHCP issues with multiple devices connected. I'm hoping someone clever on here has a suggestion. I tried calling VM to see if I could upgrade to Hub 5 but didn't manage to talk to a human. (This problem seems similar to the one reported here for Hub 3 that is marked as solved, although I'm not sure it really was. Anyway I have a Hub 4).
