Rainbird irrigation system has a plug in module that fits into the control panel outside. You are suppose to access the module remotely via pc, cellphone, tablet, etc. I can set it up by it keeps dropping the connection after a short time. I am using the new Cox router that shifts between 5ghz and 2.4ghz. Looks like the router stays at 5ghz. Rainbird says I need to switch to 2.4ghz, but I see no way of doing that on this new router. Any suggestions besides turning the module back in and manually controlling Rainbird system?
Have you tried checking the box for "use different names and passwords for 2.4 GHz and 5 GHz WiFi". See step 5 of link below for more info.
