My network broadcasts 2.4GHz and 5GHz. The 2.4GHz is named ‘Hast Wireless’, the 5GHz is named ‘Hast Wireless 5GHz’. For reasons other than the Emonpi, I need to change the Hast Wireless 5GHz to match the 2.4GHz name. I also use an Airport Express to extend the network. The reason for having both names the same is so that my phones and other computers can move more reliably between the extender/main router and between the 2.4 and 5GHz networks.
The only issue I have is that the Emonpi will not connect to Ethernet or Wifi when I change Hast Wireless 5GHz to Hast Wireless.
Is there a procedure to perform within the Emonpi so that it connects to Wifi after the name change?
I have a similar setup with both 2.4 and 5 WiFi both have their own SSID if you connect to both SSID from your phone and Computer with them set to auto connect the devices will roam between the two without any intervention.
Some 2.4GHz devices just will not connect reliably to a specific brand of AP especially if the SSID is the same for both bands. I have Ubiquiti AP and one of my Android tablets simply will not hold the connection longer than a couple of minutes. Connect it to another (cheap) AP and it is fine.
